feat: GStackBrain — 16 new skills, resolver, conventions, identity layer (v0.10.0) (#120)

Browse Source 
* feat: migrate 8 existing skills to conformance format

Add YAML frontmatter (name, version, description, triggers, tools, mutating),
Contract, Anti-Patterns, and Output Format sections to all existing skills.
Rename Workflow to Phases. Ingest becomes thin router delegating to specialized
ingestion skills (Phase 2).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add RESOLVER.md, conventions directory, and output rules

RESOLVER.md is the skill dispatcher modeled on Wintermute's AGENTS.md.
Categorized routing table: Always-on, Brain ops, Ingestion, Thinking,
Operational, Setup, Identity. Conventions directory extracts cross-cutting
rules (quality, brain-first lookup, model routing, test-before-bulk).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add skills conformance and resolver validation tests

skills-conformance.test.ts validates every skill has YAML frontmatter with
required fields, Contract, Anti-Patterns, and Output Format sections, and
manifest.json coverage. resolver.test.ts validates routing table categories,
skill path existence, and manifest-to-resolver coverage. 50 new tests.

* feat: add 9 brain skills from Wintermute (Phase 2)

Generalized from Wintermute's battle-tested skills:
- signal-detector: always-on idea+entity capture on every message
- brain-ops: brain-first lookup, read-enrich-write loop, source attribution
- idea-ingest: links/articles/tweets with author people page mandatory
- media-ingest: video/audio/PDF/book with entity extraction (absorbs video/youtube/book)
- meeting-ingestion: transcripts with attendee enrichment chaining
- citation-fixer: audit and fix citation formatting
- repo-architecture: filing rules by primary subject
- skill-creator: create skills with conformance standard + MECE check
- daily-task-manager: task lifecycle with priority levels

All Garry-specific references generalized. Core workflows preserved.
Updated RESOLVER.md and manifest.json.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add operational infrastructure + identity layer (Phase 3)

Operational skills:
- daily-task-prep: morning prep with calendar context and open threads
- cross-modal-review: quality gate via second model with refusal routing
- cron-scheduler: schedule staggering, quiet hours, wake-up override, idempotency
- reports: timestamped reports with keyword routing
- testing: skill validation framework (conformance checks)
- soul-audit: 6-phase interview generating SOUL.md, USER.md, ACCESS_POLICY.md, HEARTBEAT.md
- webhook-transforms: external events to brain signals with dead-letter queue

Identity layer:
- SOUL.md template (agent identity, generated by soul-audit)
- USER.md template (user profile, generated by soul-audit)
- ACCESS_POLICY.md template (4-tier access control)
- HEARTBEAT.md template (operational cadence)
- cross-modal.yaml convention (review pairs, refusal routing chain)

* docs: update CLAUDE.md with 24 skills, RESOLVER.md, conventions, templates

GBrain is now a GStack mod for agent platforms. Updated architecture description,
key files listing (16 new skill files, RESOLVER.md, conventions, templates), skills
section (24 skills organized by resolver categories), and testing section (new
conformance and resolver tests).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add GStack detection + mod status to gbrain init (Phase 4)

After brain initialization, gbrain init now reports:
- Number of skills loaded (from manifest.json)
- GStack detection (checks known host paths, uses gstack-global-discover if available)
- GStack install instructions if not found
- Resolver and soul-audit pointers

Also adds installDefaultTemplates() for SOUL.md/USER.md/ACCESS_POLICY.md/HEARTBEAT.md
deployment, and detectGStack() using gstack-global-discover with fallback to known paths
(DRY: doesn't reimplement GStack's host detection logic).

* docs: v0.10.0 release documentation

- CHANGELOG: 24 skills, signal detector, RESOLVER.md, soul-audit, access control,
  conventions, conformance standard, GStack detection in init
- README: updated skill section with 24 skills, resolver, conventions
- TODOS: added runtime MCP access control (P1)
- VERSION: 0.9.2 → 0.10.0
- package.json + manifest.json version bumped

* docs: add skill table to CHANGELOG v0.10.0

16-row table detailing every new skill, what it does, and why it matters.
Written to sell the upgrade, not document the implementation.

* fix: restore package.json version after merge conflict resolution

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: zero-based README rewrite for GStackBrain v0.10.0

Lead with GStack mod identity. 24 skills table organized by category.
Install block references RESOLVER.md and soul-audit. GBrain+GStack
relationship explained. Removed redundancy (733 -> 406 lines).
All essential content preserved: install, recipes, architecture,
search, commands, engines, voice, knowledge model.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: extract install block to INSTALL_FOR_AGENTS.md, simplify README

The 30-line copy-paste install block becomes one line:
"Retrieve and follow INSTALL_FOR_AGENTS.md"

Benefits: agent always gets latest instructions (no stale copy-paste),
README stays clean, install details live where agents read them.

README now leads with what GBrain does ("gives your agent a brain")
instead of GStack relationship. Removed "requires frontier model" note.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: 3 bugs in init.ts from merge conflict resolution

1. llstatSync typo (merge corruption) → lstatSync
2. __dirname undefined in ESM module → fileURLToPath polyfill
3. require('fs') in ESM → use imported readFileSync

All three would crash gbrain init at runtime. Caught by /review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add checkResolvable shared core function for resolver validation

Shared function at src/core/check-resolvable.ts validates that all skills
are reachable from RESOLVER.md, detects MECE overlaps (with whitelist for
always-on/router skills), finds gaps in frontmatter triggers, and scans
for DRY violations. Returns structured ResolvableIssue objects with
machine-parseable fix objects alongside human-readable action strings.

Three call sites: bun test, gbrain doctor, skill-creator skill.

Cleans up test/resolver.test.ts: removes stale 9-line skip list, imports
from production check-resolvable.ts instead of reimplementing parsing.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: expand doctor with resolver validation, filesystem-first architecture

Doctor now runs filesystem checks (resolver health, skill conformance) before
connecting to DB. New --fast flag skips DB checks. Falls back to filesystem-only
when DB is unavailable. Adds schema_version: 2 to JSON output, composite health
score (0-100), and structured issues array with action strings for agent parsing.

Resolver health check calls checkResolvable() and surfaces actionable fix
instructions. Link integrity check uses engine.getHealth() dead_links count.

CLI routing split: doctor dispatched before connectEngine() so filesystem
checks always run. Fixes Codex-identified blocker where doctor required DB.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add adaptive load-aware throttling and fail-improve loop

backoff.ts: System load checking (CPU via os.loadavg, memory via os.freemem),
exponential backoff with 20-attempt max guard, active hours multiplier (2x
slower during waking hours), concurrent process limit (max 2). Windows-safe:
defaults to "proceed" when os.loadavg returns zeros.

fail-improve.ts: Deterministic-first, LLM-fallback pattern with JSONL failure
logging. Cascade failure handling: when both paths fail, throws LLM error and
logs both. Log rotation at 1000 entries. Call count tracking for deterministic
hit rate metrics. Auto-generates test cases from successful LLM fallbacks.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add transcription service and enrichment-as-a-service

transcription.ts: Groq Whisper (default) with OpenAI fallback. Files >25MB
segmented via ffmpeg. Provider auto-detection from env vars. Clear error
messages for missing API keys and unsupported formats.

enrichment-service.ts: Global enrichment service callable from any ingest
pathway. Entity slug generation (people/jane-doe, companies/acme-corp),
mention counting via searchKeyword, tier auto-escalation (Tier 3→2→1 based
on mention frequency and source diversity), batch enrichment with backoff
throttling, regex-based entity extraction from text.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add data-research skill with recipe system, extraction, dedup, tracker

New skill: data-research — one parameterized pipeline for any email-to-
structured-data workflow (investor updates, donations, company metrics).
7-phase pipeline: define recipe, search, classify, extract (with extraction
integrity rule), archive, deduplicate, update tracker.

data-research.ts: Recipe validation, MRR/ARR/runway/headcount regex
extraction (battle-tested patterns), dedup with configurable tolerance,
markdown tracker parsing/appending, quarterly/monthly date windowing,
6-phase HTML email stripping with 500KB ReDoS cap.

Registers data-research in manifest.json (25th skill) and RESOLVER.md.
Fixes backoff test robustness for high-load systems.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: update project documentation for v0.10.0 infrastructure additions

CLAUDE.md: added 6 new core files (check-resolvable, backoff, fail-improve,
transcription, enrichment-service, data-research), 6 new test files, updated
skill count to 25, test file count to 34.

README.md: updated skill count to 25, added data-research to skills table.

CHANGELOG.md: added Infrastructure section documenting resolver validation,
doctor expansion, adaptive throttling, fail-improve loop, voice transcription,
enrichment service, and data-research skill.

TODOS.md: anonymized personal references.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: doctor.ts use ES module imports, harden backoff test

Replace require('fs') with ES module import in doctor.ts for consistency
with the rest of the file. Backoff test made resilient to parallel test
execution leaking module-level state.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: README rewrite with production brain stats, sample output, new infrastructure

Lead with the flex: 17,888 pages, 4,383 people, 723 companies, 526 meeting
transcripts built in 12 days. Show sample query output so readers see what
they'll get. Document self-improving infrastructure (tier auto-escalation,
fail-improve loop, doctor trajectory). Add data-research recipes to Getting
Data In. Update commands section with doctor --fix, transcribe, research
init/list. Fix stale "24" references to "25".

* fix: rename political-donations recipe to expense-tracker (sensitivity)

Renamed the built-in data-research recipe from political-donations to
expense-tracker across README, CHANGELOG, SKILL.md, and reports routing.
Same extraction patterns (amounts, dates, recipients), neutral framing.
Also renamed social-radar keyword route to social-mentions.

All notable changes to GBrain will be documented in this file.
## [0.10.0] - 2026-04-14
### Added
- **Your agent now has 24 skills, not 8.** 16 new brain skills generalized from a production deployment with 14,700+ pages. Signal detection, brain-first lookup, content ingestion (articles, video, meetings), entity enrichment, task management, cron scheduling, reports, and cross-modal review. All shipped as fat markdown files your agent reads on demand.
- **Signal detector fires on every message.** A cheap sub-agent spawns in parallel to capture original thinking and entity mentions. Ideas get preserved with exact phrasing. Entities get brain pages. The brain compounds on autopilot.
- **RESOLVER.md routes your agent to the right skill.** Modeled on a 215-line production dispatcher. Categorized routing table: always-on, brain ops, ingestion, thinking, operational. Your agent reads it, matches the user's intent, loads the skill. No slash commands needed.
- **Soul-audit builds your agent's identity.** 6-phase interactive interview generates SOUL.md (who the agent is), USER.md (who you are), ACCESS_POLICY.md (who sees what), and HEARTBEAT.md (operational cadence). Re-runnable anytime. Ships with minimal defaults so first boot is instant.
- **Access control out of the box.** 4-tier privacy policy (Full/Work/Family/None) enforced by skill instructions before every response. Template-based, configurable per user.
- **Conventions directory codifies operational discipline.** Brain-first lookup protocol, citation quality standards, model routing table, test-before-bulk rule, and cross-modal review pairs. These are the hard-won patterns that prevent bad bulk runs and silent failures.
- **`gbrain init` detects GStack and reports mod status.** After brain setup, init now shows how many skills are loaded, whether GStack is installed, and where to get it. GStack detection uses `gstack-global-discover` with fallback to known host paths.
- **Conformance standard for all skills.** Every skill now has YAML frontmatter (name, version, description, triggers, tools, mutating) plus Contract, Anti-Patterns, and Output Format sections. Two new test files validate conformance across all 25 skills.
- **Existing 8 skills migrated to conformance format.** Frontmatter added, Workflow renamed to Phases, Contract and Anti-Patterns sections added. Ingest becomes a thin router delegating to specialized ingestion skills.
### The 16 new skills
| Skill | What it does | Why it matters |
|-------|-------------|----------------|
| **signal-detector** | Fires on every message. Spawns a cheap model in parallel to capture original thinking and entity mentions. | Your brain compounds on autopilot. Every conversation is an ingest event. Miss a signal and the brain never learns it. |
| **brain-ops** | Brain-first lookup before any external API. The read-enrich-write loop that makes every response smarter. | Without this, your agent reaches for Google when the answer is already in the brain. Wastes tokens, misses context. |
| **idea-ingest** | Links, articles, tweets go into the brain with analysis, author people pages, and cross-linking. | Every article worth reading is worth remembering. The author gets a people page. The ideas get cross-linked to what you already know. |
| **media-ingest** | Video, audio, PDF, books, screenshots, GitHub repos. Transcripts, entity extraction, backlink propagation. | One skill handles every media format. Absorbs what used to be 3 separate skills (video-ingest, youtube-ingest, book-ingest). |
| **meeting-ingestion** | Transcripts become brain pages. Every attendee gets enriched. Every company discussed gets a timeline entry. | A meeting is NOT fully ingested until every entity is propagated. This is the skill that turns a transcript into 10 updated brain pages. |
| **citation-fixer** | Scans brain pages for missing or malformed `[Source: ...]` citations. Fixes formatting to match the standard. | Without citations, you can't trace facts back to where they came from. Six months later, "who said this?" has an answer. |
| **repo-architecture** | Where new brain files go. Decision protocol: primary subject determines directory, not format or source. | Prevents the #1 misfiling pattern: dumping everything in `sources/` because it came from a URL. |
| **skill-creator** | Create new skills following the conformance standard. MECE check against existing skills. Updates manifest and resolver. | Users who need a capability GBrain doesn't have can create it themselves. The skill teaches the agent how to extend itself. |
| **daily-task-manager** | Add, complete, defer, remove, review tasks with priority levels (P0-P3). Stored as a searchable brain page. | Your tasks live in the brain, not a separate app. The agent can cross-reference tasks with meeting notes and people pages. |
| **daily-task-prep** | Morning preparation. Calendar lookahead with brain context per attendee, open threads from yesterday, active task review. | Walk into every meeting with full context on every person in the room, automatically. |
| **cross-modal-review** | Spawn a different AI model to review the agent's work before committing. Refusal routing: if one model refuses, silently switch. | Two models agreeing is stronger signal than one model being thorough. Refusal routing means the user never sees "I can't do that." |
| **cron-scheduler** | Schedule staggering (5-min offsets), quiet hours (timezone-aware with wake-up override), thin job prompts. | 21 cron jobs at :00 is a thundering herd. Staggering prevents it. Quiet hours mean no 3 AM notifications. Wake-up override releases the backlog. |
| **reports** | Timestamped reports with keyword routing. "What's the latest briefing?" maps to the right report directory. | Cheap replacement for vector search on frequent queries. Don't embed. Load the file. |
| **testing** | Validates every skill has SKILL.md with frontmatter, manifest coverage, resolver coverage. The CI for your skill system. | 3 skills and you need validation. 24 skills and you need it yesterday. Catches dead references, missing sections, MECE violations. |
| **soul-audit** | 6-phase interview that generates SOUL.md, USER.md, ACCESS_POLICY.md, HEARTBEAT.md. Your agent's identity, built from your answers. | What makes Wintermute feel like Wintermute. Without personality and access control, every agent feels the same. |
| **webhook-transforms** | External events (SMS, meetings, social mentions) converted into brain pages with entity extraction. Dead-letter queue for failures. | Your brain ingests signals from everywhere. Not just conversations, but every webhook, every notification, every external event. |
### Infrastructure (new in v0.10.0)
- **Your brain now self-validates its own skill routing.** `checkResolvable()` verifies every skill is reachable from RESOLVER.md, detects MECE overlaps, flags missing triggers, and catches DRY violations. Runs from `bun test`, `gbrain doctor`, and the skill-creator skill. Every issue comes with a machine-readable fix object the agent can act on.
- **`gbrain doctor` got serious.** 8 health checks now (up from 5), plus a composite health score (0-100). Filesystem checks (resolver, conformance) run even without a database. `--fast` skips DB checks. `--json` output includes structured `issues` array with action strings so agents can parse and auto-fix.
- **Batch operations won't melt your machine anymore.** Adaptive load-aware throttling checks CPU and memory before each batch item. Exponential backoff with a 20-attempt safety cap. Active hours multiplier slows batch work during the day. Two concurrent batch process limit.
- **Your agent's classifiers get smarter automatically.** Fail-improve loop: try deterministic code first, fall back to LLM, log every fallback. Over time, the logs reveal which regex patterns are missing. Auto-generates test cases from successful LLM results. Tracks deterministic hit rate in `gbrain doctor` output.
- **Voice notes just work.** Groq Whisper transcription (with OpenAI fallback) via `transcribe_audio` operation. Files over 25MB get ffmpeg-segmented automatically. Transcripts flow through the standard import pipeline, entities get extracted, back-links get created.
- **Enrichment is now a global service, not a per-skill skill.** Every ingest pathway can call `extractAndEnrich()` to detect entities and create/update their brain pages. Tier auto-escalation: entities start at Tier 3, auto-promote to Tier 1 based on mention frequency across sources.
- **Data research: one skill for any email-to-tracker pipeline.** New `data-research` skill with parameterized YAML recipes. Extract investor updates (MRR, ARR, runway, headcount), expense receipts, company metrics from email. Battle-tested regex patterns, extraction integrity rule (save first, report second), dedup with configurable tolerance, canonical tracker pages with running totals.
### For contributors
- `test/skills-conformance.test.ts` validates every skill has valid frontmatter and required sections
- `test/resolver.test.ts` validates RESOLVER.md coverage and routing consistency
- `skills/manifest.json` now has `conformance_version` field and lists all 24 skills
- Identity templates in `templates/` (SOUL.md, USER.md, ACCESS_POLICY.md, HEARTBEAT.md)

Read the skill files in `skills/` before doing brain operations. GBrain ships 25 skills
organized by `skills/RESOLVER.md`:
**Original 8 (conformance-migrated):** ingest (thin router), query, maintain, enrich,
briefing, migrate, setup, publish.
**Brain skills (from Wintermute):** signal-detector, brain-ops, idea-ingest, media-ingest,
meeting-ingestion, citation-fixer, repo-architecture, skill-creator, daily-task-manager.
**Operational + identity:** daily-task-prep, cross-modal-review, cron-scheduler, reports,
testing, soul-audit, webhook-transforms.
**Conventions:** `skills/conventions/` has cross-cutting rules (quality, brain-first,
model-routing, test-before-bulk, cross-modal). `skills/_brain-filing-rules.md` and
`skills/_output-rules.md` are shared references.

# GBrain Installation Guide for AI Agents
Read this entire file, then follow the steps. Ask the user for API keys when needed.
Target: ~30 minutes to a fully working brain.
## Step 1: Install GBrain
```bash
git clone https://github.com/garrytan/gbrain.git ~/gbrain && cd ~/gbrain
curl -fsSL https://bun.sh/install | bash
export PATH="$HOME/.bun/bin:$PATH"
bun install && bun link
```
Verify: `gbrain --version` should print a version number. If `gbrain` is not found,
restart the shell or add the PATH export to the shell profile.
## Step 2: API Keys
Ask the user for these:
```bash
export OPENAI_API_KEY=sk-... # required for vector search
export ANTHROPIC_API_KEY=sk-ant-... # optional, improves search quality
```
Save to shell profile or `.env`. Without OpenAI, keyword search still works.
Without Anthropic, search works but skips query expansion.
## Step 3: Create the Brain
```bash
gbrain init # PGLite, no server needed
gbrain doctor --json # verify all checks pass
```
The user's markdown files (notes, docs, brain repo) are SEPARATE from this tool repo.
Ask the user where their files are, or create a new brain repo:
```bash
mkdir -p ~/brain && cd ~/brain && git init
```
Read `~/gbrain/docs/GBRAIN_RECOMMENDED_SCHEMA.md` and set up the MECE directory
structure (people/, companies/, concepts/, etc.) inside the user's brain repo,
NOT inside ~/gbrain.
## Step 4: Import and Index
```bash
gbrain import ~/brain/ --no-embed # import markdown files
gbrain embed --stale # generate vector embeddings
gbrain query "key themes across these documents?"
```
## Step 5: Load Skills
Read `~/gbrain/skills/RESOLVER.md`. This is the skill dispatcher. It tells you which
skill to read for any task. Save this to your memory permanently.
The three most important skills to adopt immediately:
1. **Signal detector** (`skills/signal-detector/SKILL.md`) — fire this on EVERY
inbound message. It captures ideas and entities in parallel. The brain compounds.
2. **Brain-ops** (`skills/brain-ops/SKILL.md`) — brain-first lookup on every response.
Check the brain before any external API call.
3. **Conventions** (`skills/conventions/quality.md`) — citation format, back-linking
iron law, source attribution. These are non-negotiable quality rules.
## Step 6: Identity (optional)
Run the soul-audit skill to customize the agent's identity:
```
Read skills/soul-audit/SKILL.md and follow it.
```
This generates SOUL.md (agent identity), USER.md (user profile), ACCESS_POLICY.md
(who sees what), and HEARTBEAT.md (operational cadence) from the user's answers.
If skipped, minimal defaults are installed automatically.
## Step 7: Recurring Jobs
Set up using your platform's scheduler (OpenClaw cron, Railway cron, crontab):
- **Live sync** (every 15 min): `gbrain sync --repo ~/brain && gbrain embed --stale`
- **Auto-update** (daily): `gbrain check-update --json` (tell user, never auto-install)
- **Dream cycle** (nightly): read `docs/guides/cron-schedule.md` for the full protocol.
Entity sweep, citation fixes, memory consolidation. This is what makes the brain
compound. Do not skip it.
- **Weekly**: `gbrain doctor --json && gbrain embed --stale`
## Step 8: Integrations
Run `gbrain integrations list`. Each recipe in `~/gbrain/recipes/` is a self-contained
installer. It tells you what credentials to ask for, how to validate, and what cron
to register. Ask the user which integrations they want (email, calendar, voice, Twitter).
Verify: `gbrain integrations doctor` (after at least one is configured)
## Step 9: Verify
Read `docs/GBRAIN_VERIFY.md` and run all 6 verification checks. Check #4 (live sync
actually works) is the most important.
## Upgrade
```bash
cd ~/gbrain && git pull origin main && bun install
```
Then run `gbrain init` to apply any schema migrations (idempotent, safe to re-run).

# GBrain
Your AI agent is smart but it doesn't know anything about your life. GBrain fixes that. Meetings, emails, tweets, calendar events, voice calls, original ideas... all of it flows into a searchable knowledge base that your agent reads before every response and writes to after every conversation. The agent gets smarter every day.
Your AI agent is smart but forgetful. GBrain gives it a brain.
> **~30 minutes to a fully working brain.** Your agent does the work. Database ready in 2 seconds (PGLite, no server). Schema, import, embeddings, and integrations take 15-30 minutes depending on brain size. You just answer questions about API keys.
>
> **Requires a frontier model.** Tested with **Claude Opus 4.6** and **GPT-5.4 Thinking**. Likely to break with smaller models.
Built by the President and CEO of Y Combinator to run his actual AI agents. The production brain powering his OpenClaw and Hermes deployments: **17,888 pages, 4,383 people, 723 companies**, 21 cron jobs running autonomously, built in 12 days. The agent ingests meetings, emails, tweets, voice calls, and original ideas while you sleep. It enriches every person and company it encounters. It fixes its own citations and consolidates memory overnight. You wake up and the brain is smarter than when you went to bed.
## Need an AI agent first?
GBrain is those patterns, generalized. 25 skills. Install in 30 minutes. Your agent does the work. As Garry's personal agent gets smarter, so does yours.
> **~30 minutes to a fully working brain.** Database ready in 2 seconds (PGLite, no server). You just answer questions about API keys.
## Install
### On an agent platform (recommended)
GBrain is designed to be installed and operated by an AI agent. If you don't have one running yet:
- **[OpenClaw](https://openclaw.ai)** — Deploy [AlphaClaw on Render](https://render.com/deploy?repo=https://github.com/chrysb/alphaclaw) (one click, requires 8GB+ RAM instance)
- **[Hermes Agent](https://github.com/NousResearch/hermes-agent)** — Deploy on [Railway using this template](https://github.com/praveen-ks-2001/hermes-agent-template) (one click)
- **[OpenClaw](https://openclaw.ai)** ... Deploy [AlphaClaw on Render](https://render.com/deploy?repo=https://github.com/chrysb/alphaclaw) (one click, 8GB+ RAM)
- **[Hermes Agent](https://github.com/NousResearch/hermes-agent)** ... Deploy on [Railway](https://github.com/praveen-ks-2001/hermes-agent-template) (one click)
## Start here
**https://github.com/garrytan/gbrain** — clone this repo into your agent's filesystem. It's home base for docs, skills, upgrades, and recipes. To upgrade later: `git pull origin main && bun install`.
Copy this block into [OpenClaw](https://openclaw.ai), [Hermes](https://github.com/NousResearch/hermes-agent), or any persistent AI agent. The agent reads the docs, does the work, and asks you for API keys. ~30 minutes.
Paste this into your agent:
```
INSTALL:
git clone https://github.com/garrytan/gbrain.git ~/gbrain && cd ~/gbrain
curl -fsSL https://bun.sh/install | bash
export PATH="$HOME/.bun/bin:$PATH"
bun install && bun link
Verify: gbrain --version
(If gbrain is not found, restart your shell or add the PATH export
to your shell profile.)
API KEYS — ask the user for these:
export OPENAI_API_KEY=sk-... # required for vector search
export ANTHROPIC_API_KEY=sk-ant-... # optional, improves search quality
Save to shell profile or .env. Without OpenAI, keyword search still
works. Without Anthropic, search works but skips query expansion.
SET UP THE BRAIN:
gbrain init # PGLite, no server needed
Verify: gbrain doctor --json # all checks pass
The user's markdown files (notes, docs, brain repo) are SEPARATE from
this tool repo. Ask the user where their files are, or create a new
brain repo: mkdir -p ~/brain && cd ~/brain && git init
Read ~/gbrain/docs/GBRAIN_RECOMMENDED_SCHEMA.md — set up the MECE
directory structure (people/, companies/, concepts/, etc.) inside the
user's brain repo, NOT inside ~/gbrain.
gbrain import ~/brain/ --no-embed # import markdown files
gbrain embed --stale # generate vector embeddings
gbrain query "key themes across these documents?"
GO LIVE — read and permanently adopt these docs from ~/gbrain/:
docs/GBRAIN_SKILLPACK.md — the full agent playbook. Save to your
memory: brain-first lookup on every message, entity detection,
back-linking. This changes how you behave permanently.
Set up recurring jobs using your platform's scheduler (crontab,
OpenClaw cron, Railway cron, or a process manager):
- Live sync (every 15 min): gbrain sync --repo ~/brain && gbrain embed --stale
- Auto-update (daily): gbrain check-update --json (tell user, never auto-install)
- Dream cycle (nightly): read docs/guides/cron-schedule.md for the
full protocol — entity sweep, citation fixes, memory consolidation.
This is what makes the brain compound. Do not skip it.
- Weekly: gbrain doctor --json && gbrain embed --stale
docs/GBRAIN_VERIFY.md — run all 6 verification checks. #4 (live sync
actually works) is the most important.
INTEGRATIONS — run gbrain integrations list. Each recipe in
~/gbrain/recipes/ is a self-contained installer: it tells you what
credentials to ask for, how to validate, and what cron to register.
Ask the user which integrations they want (email, calendar, voice,
Twitter). Set up the ones they have credentials for.
Verify: gbrain integrations doctor (after at least one is configured)
UPGRADE: cd ~/gbrain && git pull origin main && bun install

## The 25 Skills
GBrain ships 25 skills organized by `skills/RESOLVER.md`. The resolver tells your agent which skill to read for any task.
[Skill files are code.](https://x.com/garrytan/status/2042925773300908103) They're the most powerful way to get knowledge work done. A skill file is a fat markdown document that encodes an entire workflow: when to fire, what to check, how to chain with other skills, what quality bar to enforce. The agent reads the skill and executes it. Skills can also call deterministic TypeScript code bundled in GBrain (search, import, embed, sync) for the parts that shouldn't be left to LLM judgment. [Thin harness, fat skills](docs/ethos/THIN_HARNESS_FAT_SKILLS.md): the intelligence lives in the skills, not the runtime.
### Always-on
| Skill | What it does |
|-------|-------------|
| **signal-detector** | Fires on every message. Spawns a cheap model in parallel to capture original thinking and entity mentions. The brain compounds on autopilot. |
| **brain-ops** | Brain-first lookup before any external API. The read-enrich-write loop that makes every response smarter. |
### Content ingestion
| Skill | What it does |
|-------|-------------|
| **ingest** | Thin router. Detects input type and delegates to the right ingestion skill. |
| **idea-ingest** | Links, articles, tweets become brain pages with analysis, author people pages, and cross-linking. |
| **media-ingest** | Video, audio, PDF, books, screenshots, GitHub repos. Transcripts, entity extraction, backlink propagation. |
| **meeting-ingestion** | Transcripts become brain pages. Every attendee gets enriched. Every company gets a timeline entry. |
### Brain operations
| Skill | What it does |
|-------|-------------|
| **enrich** | Tiered enrichment (Tier 1/2/3). Creates and updates person/company pages with compiled truth and timelines. |
| **query** | 3-layer search with synthesis and citations. Says "the brain doesn't have info on X" instead of hallucinating. |
| **maintain** | Periodic health: stale pages, orphans, dead links, citation audit, back-link enforcement, tag consistency. |
| **citation-fixer** | Scans pages for missing or malformed citations. Fixes format to match the standard. |
| **repo-architecture** | Where new brain files go. Decision protocol: primary subject determines directory, not format. |
| **publish** | Share brain pages as password-protected HTML. Zero LLM calls. |
| **data-research** | Structured data research with parameterized YAML recipes. Extract investor updates, expenses, company metrics from email. |
### Operational
| Skill | What it does |
|-------|-------------|
| **daily-task-manager** | Task lifecycle with priority levels (P0-P3). Stored as searchable brain pages. |
| **daily-task-prep** | Morning prep: calendar lookahead with brain context per attendee, open threads, task review. |
| **cron-scheduler** | Schedule staggering (5-min offsets), quiet hours (timezone-aware with wake-up override), idempotency. |
| **reports** | Timestamped reports with keyword routing. "What's the latest briefing?" finds it instantly. |
| **cross-modal-review** | Quality gate via second model. Refusal routing: if one model refuses, silently switch. |
| **webhook-transforms** | External events (SMS, meetings, social mentions) converted into brain pages with entity extraction. |
| **testing** | Validates every skill has SKILL.md with frontmatter, manifest coverage, resolver coverage. |
| **skill-creator** | Create new skills following the conformance standard. MECE check against existing skills. |
### Identity and setup
| Skill | What it does |
|-------|-------------|
| **soul-audit** | 6-phase interview generating SOUL.md (agent identity), USER.md (user profile), ACCESS_POLICY.md (4-tier privacy), HEARTBEAT.md (operational cadence). |
| **setup** | Auto-provision PGLite or Supabase. First import. GStack detection. |
| **migrate** | Universal migration from Obsidian, Notion, Logseq, markdown, CSV, JSON, Roam. |
| **briefing** | Daily briefing with meeting context, active deals, and citation tracking. |
### Conventions
Cross-cutting rules in `skills/conventions/`:
- **quality.md** ... citations, back-links, notability gate, source attribution
- **brain-first.md** ... 5-step lookup before any external API call
- **model-routing.md** ... which model for which task
- **test-before-bulk.md** ... test 3-5 items before any batch operation
- **cross-modal.yaml** ... review pairs and refusal routing chain
## How It Works
```
Signal arrives (meeting, email, tweet, link)
-> Signal detector captures ideas + entities (parallel, never blocks)
-> Brain-ops: check the brain first (gbrain search, gbrain get)
-> Respond with full context
-> Write: update brain pages with new information + citations
-> Sync: gbrain indexes changes for next query
```
Every cycle adds knowledge. The agent enriches a person page after a meeting. Next time that person comes up, the agent already has context. The difference compounds daily.
The system gets smarter on its own. Entity enrichment auto-escalates: a person mentioned once gets a stub page (Tier 3). After 3 mentions across different sources, they get web + social enrichment (Tier 2). After a meeting or 8+ mentions, full pipeline (Tier 1). The brain learns who matters without being told. Deterministic classifiers improve over time via a fail-improve loop that logs every LLM fallback and generates better regex patterns from the failures. `gbrain doctor` shows the trajectory: "intent classifier: 87% deterministic, up from 40% in week 1."
> "Prep me for my meeting with Jordan in 30 minutes"
> ... pulls dossier, shared history, recent activity, open threads
> "What have I said about the relationship between shame and founder performance?"
> ... searches YOUR thinking, not the internet
## Getting Data In
Once GBrain is installed, your agent needs data flowing in. GBrain ships integration recipes that your agent sets up for you. It reads the recipe, asks for API keys, validates each one, and runs a smoke test. [Markdown is code](docs/ethos/THIN_HARNESS_FAT_SKILLS.md)... the recipe IS the installer.
GBrain ships integration recipes that your agent sets up for you. Each recipe tells the agent what credentials to ask for, how to validate, and what cron to register.
| Recipe | Requires | What It Does |
|--------|----------|-------------|
| [Public Tunnel](recipes/ngrok-tunnel.md) | — | Fixed URL for MCP + voice (ngrok Hobby $8/mo) |
| [Credential Gateway](recipes/credential-gateway.md) | — | Gmail + Calendar access (ClawVisor or Google OAuth) |
| [Voice-to-Brain](recipes/twilio-voice-brain.md) | ngrok-tunnel | Phone calls → brain pages (Twilio + OpenAI Realtime) |
| [Email-to-Brain](recipes/email-to-brain.md) | credential-gateway | Gmail → entity pages (deterministic collector) |
| [X-to-Brain](recipes/x-to-brain.md) | — | Twitter → brain pages (timeline + mentions + deletions) |
| [Calendar-to-Brain](recipes/calendar-to-brain.md) | credential-gateway | Google Calendar → searchable daily pages |
| [Meeting Sync](recipes/meeting-sync.md) | — | Circleback transcripts → brain pages with attendees |
| [Credential Gateway](recipes/credential-gateway.md) | — | Gmail + Calendar access |
| [Voice-to-Brain](recipes/twilio-voice-brain.md) | ngrok-tunnel | Phone calls to brain pages (Twilio + OpenAI Realtime) |
| [Email-to-Brain](recipes/email-to-brain.md) | credential-gateway | Gmail to entity pages |
| [X-to-Brain](recipes/x-to-brain.md) | — | Twitter timeline + mentions + deletions |
| [Calendar-to-Brain](recipes/calendar-to-brain.md) | credential-gateway | Google Calendar to searchable daily pages |
| [Meeting Sync](recipes/meeting-sync.md) | — | Circleback transcripts to brain pages with attendees |
Run `gbrain integrations` to see status. Dependencies resolve automatically. See [Getting Data In](docs/integrations/README.md) for the full guide.
**Data research recipes** extract structured data from email into tracked brain pages. Built-in recipes for investor updates (MRR, ARR, runway, headcount), expense tracking, and company metrics. Create your own with `gbrain research init`.
## The Compounding Thesis
Run `gbrain integrations` to see status.
Most tools help you find things. GBrain makes you smarter over time.
## GBrain + GStack
```
Signal arrives (meeting, email, tweet, link)
→ Agent detects entities (people, companies, ideas)
→ READ: check the brain first (gbrain search, gbrain get)
→ Respond with full context
→ WRITE: update brain pages with new information
→ Sync: gbrain indexes changes for next query
```
[GStack](https://github.com/garrytan/gstack) is the engine. GBrain is the mod.
Every cycle through this loop adds knowledge. The agent enriches a person page after a meeting. Next time that person comes up, the agent already has context. You never start from zero.
- **[GStack](https://github.com/garrytan/gstack)** = coding skills (ship, review, QA, investigate, office-hours, retro). 70,000+ stars, 30,000 developers per day. When your agent codes on itself, it uses GStack.
- **GBrain** = everything-else skills (brain ops, signal detection, ingestion, enrichment, cron, reports, identity). When your agent remembers, thinks, and operates, it uses GBrain.
- **`hosts/gbrain.ts`** = the bridge. Tells GStack's coding skills to check the brain before coding.
An agent without this loop answers from stale context. An agent with it gets smarter every conversation. The difference compounds daily.
> "Who should I invite to dinner who knows both Pedro and Diana?"
> — cross-references the social graph across 3,000+ people pages
> "What have I said about the relationship between shame and founder performance?"
> — searches YOUR thinking, not the internet
> "Prep me for my meeting with Jordan in 30 minutes"
> — pulls dossier, shared history, recent activity, open threads
## Voice: "Her" Out of the Box
The voice integration is the strongest demonstration of why a personal brain matters.
Call a phone number. Your AI answers. It knows who's calling, pulls their full context
from thousands of people pages, references your last meeting, and responds like someone
who actually knows your world. When the call ends, a structured brain page appears with
the transcript, entity detection, and cross-references.
This isn't a demo. It runs on a real phone number, screens unknown callers, and gets
smarter with every call. Your agent picks its own name and personality. WebRTC works in
a browser tab with zero setup. A real phone number is optional.

The voice recipe ships with GBrain: [Voice-to-Brain](recipes/twilio-voice-brain.md).
Your agent installs it, sets up the voice server, and you have a working AI phone line
in 30 minutes. 25 production patterns from a real deployment included.
## How this happened
I was setting up my [OpenClaw](https://openclaw.ai) agent and started a markdown brain repo. One page per person, one page per company, compiled truth on top, append-only timeline on the bottom. The agent got smarter the more it knew, so I kept feeding it. Within a week I had 10,000+ markdown files, 3,000+ people with compiled dossiers, 13 years of calendar data, 280+ meeting transcripts, and 300+ captured original ideas.
The agent runs while I sleep. The dream cycle scans every conversation, enriches missing entities, fixes broken citations, and consolidates memory. I wake up and the brain is smarter than when I went to sleep. See the [cron schedule guide](docs/guides/cron-schedule.md) for setup.
**PGLite runs locally by default.** `gbrain init` gives you embedded Postgres with pgvector, hybrid search, and all 37 operations. No server, no subscription. When your brain outgrows local (1000+ files, multi-device access, remote MCP), `gbrain migrate --to supabase` moves everything to managed Postgres.
`gbrain init` detects if GStack is installed and reports mod status. If GStack isn't there, it tells you how to get it.

The repo is the system of record. GBrain is the retrieval layer. The agent reads and writes through both. Human always wins — you can edit any markdown file directly and `gbrain sync` picks up the changes.

## What a Production Agent Looks Like
## The Knowledge Model
The numbers above aren't theoretical. They come from a real deployment documented in [GBRAIN_SKILLPACK.md](docs/GBRAIN_SKILLPACK.md) — a reference architecture for how a production AI agent uses gbrain as its knowledge backbone.
**Read the skillpack.** It's the most important doc in this repo. It tells your agent HOW to use gbrain, not just what commands exist:
- **The brain-agent loop** — the read-write cycle that makes knowledge compound
- **Entity detection** — spawn on every message, capture people/companies/original ideas
- **Enrichment pipeline** — 7-step protocol with tiered API spend
- **Meeting ingestion** — transcript to brain pages with entity propagation
- **Source attribution** — every fact traceable to where it came from
- **Reference cron schedule** — 20+ recurring jobs that keep the brain alive
Without the skillpack, your agent has tools but no playbook. With it, the agent knows when to read, when to write, how to enrich, and how to keep the brain alive autonomously. It's a pattern book, not a tutorial. "Here's what works, here's why."
## How gbrain fits with OpenClaw/Hermes
GBrain is world knowledge — people, companies, deals, meetings, concepts, your original thinking. It's the long-term memory of what you know about the world.
[OpenClaw](https://openclaw.ai) agent memory (`memory_search`) is operational state — preferences, decisions, session context, how the agent should behave.
They're complementary:
| Layer | What it stores | How to query |
|-------|---------------|-------------|
| **gbrain** | People, companies, meetings, ideas, media | `gbrain search`, `gbrain query`, `gbrain get` |
| **Agent memory** | Preferences, decisions, operational config | `memory_search` |
| **Session context** | Current conversation | (automatic) |
All three should be checked. GBrain for facts about the world. Memory for agent config. Session for immediate context. Install via `openclaw skills install gbrain`.
## The compounding effect
The real value isn't search. It's what happens after a few weeks of use.
You take a meeting with someone. The agent writes a brain page for them, links it to their company, tags it with the deal. Next week someone mentions that company in a different context. The agent already has the full picture: who you talked to, what you discussed, what threads are open. You didn't do anything. The brain already had it.
## Install
### Prerequisites
**Zero-config start (PGLite).** `gbrain init` creates a local embedded Postgres brain. No accounts, no server, no API keys. Keyword search works immediately. Add API keys later for vector search and LLM-powered features.
**For production scale (Supabase).** When your brain outgrows local, `gbrain migrate --to supabase` moves everything to managed Postgres:
| Dependency | What it's for | How to get it |
|------------|--------------|---------------|
| **Supabase account** | Postgres + pgvector database | [supabase.com](https://supabase.com) (Pro tier, $25/mo for 8GB) |
| **OpenAI API key** | Embeddings (text-embedding-3-large) | [platform.openai.com/api-keys](https://platform.openai.com/api-keys) |
| **Anthropic API key** | Multi-query expansion + LLM chunking (Haiku) | [console.anthropic.com](https://console.anthropic.com) |
Set the API keys as environment variables:
```bash
export OPENAI_API_KEY=sk-...
export ANTHROPIC_API_KEY=sk-ant-...
```
The Supabase connection URL is configured during `gbrain init --supabase`. The OpenAI and Anthropic SDKs read their keys from the environment automatically.
Without an OpenAI key, search still works (keyword only, no vector search). Without an Anthropic key, search still works (no multi-query expansion, no LLM chunking).
### GBrain without OpenClaw
GBrain works with any AI agent, any MCP client, or no agent at all. Three paths:
#### Standalone CLI
Install globally and use gbrain from the terminal:
```bash
bun add -g github:garrytan/gbrain
gbrain init # PGLite (local, no server needed)
gbrain import ~/git/brain/ # index your markdown
gbrain query "what themes show up across my notes?"
```
Run `gbrain --help` for the full list of commands.
#### MCP server (Claude Code, Cursor, Windsurf, etc.)
GBrain exposes 30 MCP tools via stdio. Add this to your MCP client config:
**Claude Code** (`~/.claude/server.json`):
```json
{
"mcpServers": {
"gbrain": {
"command": "gbrain",
"args": ["serve"]
}
}
}
```
**Cursor** (Settings > MCP Servers):
```json
{
"gbrain": {
"command": "gbrain",
"args": ["serve"]
}
}
```
This gives your agent `get_page`, `put_page`, `search`, `query`, `add_link`, `traverse_graph`, `sync_brain`, `file_upload`, and 22 more tools. All generated from the same operation definitions as the CLI.
#### Remote MCP Server (Claude Desktop, Cowork, Perplexity)
Access your brain from any device, any AI client. Run `gbrain serve` behind an HTTP
server with a public tunnel:
```bash
# Set up a public tunnel (see recipes/ngrok-tunnel.md)
ngrok http 8787 --url your-brain.ngrok.app
# Create a bearer token for your client
bun run src/commands/auth.ts create "claude-desktop"
```
Then add to your AI client:
- **Claude Code:** `claude mcp add gbrain -t http https://your-brain.ngrok.app/mcp -H "Authorization: Bearer TOKEN"`
- **Claude Desktop:** Settings > Integrations > Add (NOT JSON config, [details](docs/mcp/CLAUDE_DESKTOP.md))
- **Perplexity:** Settings > Connectors > Add remote MCP ([details](docs/mcp/PERPLEXITY.md))
Per-client setup guides: [`docs/mcp/`](docs/mcp/DEPLOY.md)
ChatGPT support requires OAuth 2.1 (not yet implemented). Self-hosted alternatives (Tailscale Funnel, ngrok) documented in [`docs/mcp/ALTERNATIVES.md`](docs/mcp/ALTERNATIVES.md).
**The tools are not enough.** Your agent also needs the playbook: read [GBRAIN_SKILLPACK.md](docs/GBRAIN_SKILLPACK.md) and paste the relevant sections into your agent's system prompt or project instructions. The skillpack tells the agent WHEN and HOW to use each tool: read before responding, write after learning, detect entities on every message, back-link everything.
The skill markdown files in `skills/` are standalone instruction sets. Copy them into your agent's context:
| Skill file | What the agent learns |
|------------|----------------------|
| `skills/ingest/SKILL.md` | How to import meetings, docs, articles |
| `skills/query/SKILL.md` | 3-layer search with synthesis and citations |
| `skills/maintain/SKILL.md` | Periodic health: stale pages, orphans, dead links |
| `skills/enrich/SKILL.md` | Enrich pages from external APIs |
| `skills/briefing/SKILL.md` | Daily briefing with meeting prep |
| `skills/migrate/SKILL.md` | Migrate from Obsidian, Notion, Logseq, etc. |
#### As a TypeScript library
```bash
bun add github:garrytan/gbrain
```
```typescript
import { createEngine } from 'gbrain';
// PGLite (local, no server)
const engine = createEngine('pglite');
await engine.connect({ database_path: '~/.gbrain/brain.pglite' });
await engine.initSchema();
// Or Postgres (Supabase / self-hosted)
// const engine = createEngine('postgres');
// await engine.connect({ database_url: process.env.DATABASE_URL });
// await engine.initSchema();
// Search
const results = await engine.searchKeyword('startup growth');
// Read
const page = await engine.getPage('people/pedro-franceschi');
// Write
await engine.putPage('concepts/superlinear-returns', {
type: 'concept',
title: 'Superlinear Returns',
compiled_truth: 'Paul Graham argues that returns in many fields are superlinear...',
timeline: '- 2023-10-01: Published on paulgraham.com',
});
```
The `BrainEngine` interface is pluggable. `createEngine()` accepts `'pglite'` or `'postgres'`. See `docs/ENGINES.md` for details.
PGLite (default) requires no external database. For production scale (7K+ pages, multi-device, remote MCP), use Supabase Pro ($25/mo).
## Upgrade
```bash
cd ~/gbrain && git pull origin main && bun install
```
Then run `gbrain init` to apply any schema migrations (idempotent, safe to re-run).
## Setup details
`gbrain init` defaults to PGLite (embedded Postgres 17.5 via WASM). No accounts, no server. Config saved to `~/.gbrain/config.json`.
```bash
gbrain init # PGLite (default)
gbrain init --supabase # guided wizard for Supabase
gbrain init --url <conn> # any Postgres with pgvector
```
Import is idempotent. Re-running skips unchanged files (SHA-256 content hash). ~30s for text import of 7,000 files, ~10-15 min for embedding.
## File storage and migration
Brain repos accumulate binary files: images, PDFs, audio recordings, raw API responses. A repo with 3,000 markdown pages might have 2GB of binaries making `git clone` painful.
GBrain has a three-stage migration lifecycle that moves binaries to cloud storage while preserving every reference:
```
Local files in git repo
│
▼ gbrain files mirror <dir>
Cloud copy exists, local files untouched
│
▼ gbrain files redirect <dir>
Local files replaced with .redirect breadcrumbs (tiny YAML pointers)
│
▼ gbrain files clean <dir>
Breadcrumbs removed, cloud is the only copy
```
Every stage is reversible until `clean`:
```bash
# Stage 1: Copy to cloud (git repo unchanged)
gbrain files mirror ~/git/brain/attachments/ --dry-run # preview first
gbrain files mirror ~/git/brain/attachments/
# Stage 2: Replace local files with breadcrumbs
gbrain files redirect ~/git/brain/attachments/ --dry-run
gbrain files redirect ~/git/brain/attachments/
# Your git repo just dropped from 2GB to 50MB
# Undo: download everything back from cloud
gbrain files restore ~/git/brain/attachments/
# Stage 3: Remove breadcrumbs (irreversible, cloud is the only copy)
gbrain files clean ~/git/brain/attachments/ --yes
```
**Storage backends:** S3-compatible (AWS S3, Cloudflare R2, MinIO), Supabase Storage, or local filesystem. Configured during `gbrain init`.
Additional file commands:
```bash
gbrain files list [slug] # list files for a page (or all)
gbrain files upload <file> --page <slug> # upload file linked to page
gbrain files sync <dir> # bulk upload directory
gbrain files verify # verify all uploads match local
gbrain files status # show migration status of directories
gbrain files unmirror <dir> # remove mirror marker (files stay in cloud)
```
The file resolver (`src/core/file-resolver.ts`) handles fallback automatically: if a local file is missing, it checks for a `.redirect` breadcrumb, then a `.supabase` marker, and resolves to the cloud URL. Code that references files by path keeps working after migration.

## Search
## How search works
Hybrid search: vector + keyword + RRF fusion + multi-query expansion + 4-layer dedup.
```
Query: "when should you ignore conventional wisdom?"
|
Intent classifier (zero-latency, no LLM)
→ entity? temporal? event? general?
→ auto-selects detail level
|
Multi-query expansion (Claude Haiku)
"contrarian thinking startups", "going against the crowd"
|
+----+----+
| |
Vector Keyword
(HNSW (tsvector +
cosine) ts_rank)
| |
+----+----+
|
RRF Fusion: score = sum(1/(60 + rank))
→ normalize to 0-1
→ 2x compiled truth boost (entity queries)
|
Cosine re-scoring (0.7 * RRF + 0.3 * cosine)
→ query-specific chunk ranking
|
4-Layer Dedup + compiled truth guarantee
1. Top 3 chunks per page
2. Text similarity > 0.85
3. Type diversity (60% cap)
4. Per-page chunk cap (2)
5. Guarantee compiled truth per page
|
Results
Query
-> Intent classifier (entity? temporal? event? general?)
-> Multi-query expansion (Claude Haiku)
-> Vector search (HNSW cosine) + Keyword search (tsvector)
-> RRF fusion: score = sum(1/(60 + rank))
-> Cosine re-scoring + compiled truth boost
-> 4-layer dedup + compiled truth guarantee
-> Results
```
Keyword search alone misses conceptual matches. "Ignore conventional wisdom" won't find an essay titled "The Bus Ticket Theory of Genius" even though it's exactly about that. Vector search alone misses exact phrases when the embedding is diluted by surrounding text. RRF fusion gets both right. Multi-query expansion catches phrasings you didn't think of.
Keyword alone misses conceptual matches. Vector alone misses exact phrases. RRF gets both. Search quality is benchmarked and reproducible: `gbrain eval --qrels queries.json` measures P@k, Recall@k, MRR, and nDCG@k. A/B test config changes before deploying them.
The query intent classifier reads your query and picks the right search mode. "Who is Alice?" surfaces compiled truth assessments. "When did we last meet Alice?" surfaces timeline entries with dates. No LLM call, just pattern matching. Use `--detail low/medium/high` to override.
## Voice
Search quality is benchmarked: 29 fictional pages, 20 queries, graded relevance. Run `bun run test/benchmark-search-quality.ts` to reproduce. Measure changes with `gbrain eval --qrels queries.json`.
Call a phone number. Your AI answers. It knows who's calling, pulls their full context from the brain, and responds like someone who actually knows your world. When the call ends, a brain page appears with the transcript, entity detection, and cross-references.

```
Indexes: B-tree on slug/type, GIN on frontmatter/search_vector, HNSW on embeddings, pg_trgm on title for fuzzy slug resolution.
## Chunking
Three strategies, dispatched by content type:
**Recursive** (timeline, bulk import): 5-level delimiter hierarchy (paragraphs, lines, sentences, clauses, words). 300-word chunks with 50-word sentence-aware overlap. Fast, predictable, lossless.
**Semantic** (compiled truth): Embeds each sentence, computes adjacent cosine similarities, applies Savitzky-Golay smoothing to find topic boundaries. Falls back to recursive on failure. Best quality for intelligence assessments.
**LLM-guided** (high-value content, on request): Pre-splits into 128-word candidates, asks Claude Haiku to identify topic shifts in sliding windows. 3 retries per window. Most expensive, best results.

## Library and MCP details
See [GBrain without OpenClaw](#gbrain-without-openclaw) above for library usage examples, MCP server config, and skill file loading.
The `BrainEngine` interface is pluggable. See `docs/ENGINES.md` for how to add backends. 30 MCP tools are generated from the contract-first `operations.ts`. Parity tests verify structural identity between CLI, MCP, and tools-json.
## Skills
Fat markdown files that tell AI agents HOW to use gbrain. No skill logic in the binary.
| Skill | What it does |
|-------|-------------|
| **ingest** | Ingest meetings, docs, articles. Updates compiled truth (rewrite, not append), appends timeline, creates cross-reference links across all mentioned entities. |
| **query** | 3-layer search (keyword + vector + structured) with synthesis and citations. Says "the brain doesn't have info on X" rather than hallucinating. |
| **maintain** | Periodic health: find contradictions, stale compiled truth, orphan pages, dead links, tag inconsistency, missing embeddings, overdue threads. |
| **enrich** | Enrich pages from external APIs. Raw data stored separately, distilled highlights go to compiled truth. |
| **briefing** | Daily briefing: today's meetings with participant context, active deals with deadlines, time-sensitive threads, recent changes. |
| **migrate** | Universal migration from Obsidian (wikilinks to gbrain links), Notion (stripped UUIDs), Logseq (block refs), plain markdown, CSV, JSON, Roam. |
| **setup** | Set up GBrain from scratch: auto-provision Supabase via CLI, AGENTS.md injection, import, sync. Target TTHW < 2 min. |

Embedding, chunking, and search fusion are engine-agnostic. Only raw keyword search (`searchKeyword`) and raw vector search (`searchVector`) are engine-specific. RRF fusion, multi-query expansion, and 4-layer dedup run above the engine on `SearchResult[]` arrays. Both engines use the same SQL (PGLite runs real Postgres, not a separate dialect).
PGLite: embedded Postgres, no server, zero config. When your brain outgrows local (1000+ files, multi-device), `gbrain migrate --to supabase` moves everything.
## Storage estimates
## File Storage
For a brain with ~7,500 pages:
Brain repos accumulate binaries. GBrain has a three-stage migration:
| Component | Size |
|-----------|------|
| Page text (compiled_truth + timeline) | ~150MB |
| JSONB frontmatter + indexes | ~70MB |
| Content chunks (~22K, text) | ~80MB |
| Embeddings (22K x 1536 floats) | ~134MB |
| HNSW index overhead | ~270MB |
| Links, tags, timeline, versions | ~50MB |
| **Total** | **~750MB** |
```bash
gbrain files mirror <dir> # copy to cloud, local untouched
gbrain files redirect <dir> # replace local with .redirect pointers
gbrain files clean <dir> # remove pointers, cloud only
gbrain files restore <dir> # download everything back (undo)
```
Supabase free tier (500MB) won't fit a large brain. Supabase Pro ($25/mo, 8GB) is the starting point.
Storage backends: S3-compatible (AWS, R2, MinIO), Supabase Storage, or local.
Initial embedding cost: ~$4-5 for 7,500 pages via OpenAI text-embedding-3-large.

## Origin Story
I was setting up my [OpenClaw](https://openclaw.ai) agent and started a markdown brain repo. One page per person, one page per company, compiled truth on top, timeline on the bottom. Within a week: 10,000+ files, 3,000+ people, 13 years of calendar data, 280+ meeting transcripts, 300+ captured ideas.
The agent runs while I sleep. The dream cycle scans every conversation, enriches missing entities, fixes broken citations, consolidates memory. I wake up and the brain is smarter than when I went to sleep.
The skills in this repo are those patterns, generalized. What took 11 days to build by hand ships as a mod you install in 30 minutes.

## Disambiguation rules
When multiple skills could match:
1. Prefer the most specific skill (meeting-ingestion over ingest)
2. If the user mentions a URL, route by content type (link → idea-ingest, video → media-ingest)
3. If the user mentions a person/company, check if enrich or query fits better
4. Chaining is explicit in each skill's Phases section
5. When in doubt, ask the user
## Conventions (cross-cutting)
These apply to ALL brain-writing skills:
- `skills/conventions/quality.md` — citations, back-links, notability gate
- `skills/conventions/brain-first.md` — check brain before external APIs
- `skills/_brain-filing-rules.md` — where files go
- `skills/_output-rules.md` — output quality standards

# Output Rules
Cross-cutting output quality standards for all brain-writing skills.
## Deterministic Links
All links in brain pages MUST be deterministic (built from actual data, not composed
by the LLM). Never guess a URL or path. Build it from the slug, the commit hash, or
the API response.
- Brain page links: `[page title](type/slug.md)`
- Commit links: `[abc1234](https://github.com/{owner}/{repo}/commit/abc1234)`
- External links: use the actual URL from the source, never reconstruct it
## No Slop
Brain pages are not chat output. They are durable knowledge artifacts.
- No filler phrases ("It's worth noting that...", "Interestingly...")
- No hedging when facts are cited ("According to the source, X is true" not "X might be true")
- No LLM preamble ("I've created...", "Here's the updated...", "Certainly!")
- No placeholder dates ("YYYY-MM-DD", "recently", "in the near future")
- Short paragraphs. Concrete facts. Inline citations.
## Exact Phrasing Preservation
When capturing someone's original thinking, use their exact words. Don't paraphrase.
Don't clean up grammar. The language IS the insight.
- Direct quotes: preserve verbatim in quote blocks
- Ideas and frameworks: use the person's own terminology for slugs and titles
- Observations: capture the phrasing, not a sanitized version
## Title Quality
Page titles should be:
- Descriptive enough to identify the page from a search result
- Short enough to scan in a list (under 60 characters)
- NOT sentences ("Meeting with Pedro" not "Meeting with Pedro about the new deal structure")
- NOT generic ("Pedro Franceschi" not "Person Page")

# Brain Operations — The Ambient Context Layer
The brain is not an archive. It is a live context membrane that every interaction
flows through in both directions.
> **Convention:** See `skills/conventions/brain-first.md` for the 5-step lookup protocol.
> **Convention:** See `skills/conventions/quality.md` for citation and back-link rules.
## Contract
This skill guarantees:
- Brain is checked BEFORE any external API call (brain-first lookup)
- Every inbound signal triggers the READ → ENRICH → WRITE loop
- Every outbound response checks brain for relevant context
- Source attribution on every fact written (inline `[Source: ...]` citations)
- User's direct statements are highest-authority data
- Back-links maintained on every brain write (Iron Law)
## Iron Law: Back-Linking (MANDATORY)
Every mention of a person or company with a brain page MUST create a back-link
FROM that entity's page TO the page mentioning them. An unlinked mention is a
broken brain. See `skills/conventions/quality.md` for format.
## Phases
### Phase 1: Brain-First Lookup (MANDATORY)
Before using ANY external API to research a person, company, or topic:
1. `gbrain search "name"` — keyword search for existing pages
2. `gbrain query "natural question about name"` — hybrid search for context
3. `gbrain get <slug>` — if you know the slug, read the full page
4. Check backlinks: who references this entity?
5. Check timeline: recent events involving this entity
The brain almost always has something. External APIs fill gaps, not start from scratch.
### Phase 2: On Every Inbound Signal (READ → ENRICH → WRITE)
Every message, meeting, email, or conversation that references a person or company:
1. **Detect entities** — people, companies, deals mentioned
2. **Load brain pages** — read existing pages for context before responding
3. **Identify new information** — what does this signal tell us that the page doesn't know?
4. **Write it back** — update the brain page with new info + timeline entry + source citation
5. **Create if missing** — if notable and no page exists, create via enrich skill
**User's direct statements are the highest-value data source.** Write them to brain
pages immediately with attribution `[Source: User, YYYY-MM-DD]`.
### Phase 3: On Every Outbound Response (READ → PULL → RESPOND)
Before answering any question about a person, company, or topic:
1. **Check the brain** — read relevant pages
2. **Pull context** — use compiled truth + recent timeline
3. **Respond with context** — the brain makes every answer better
Don't answer from general knowledge when a brain page exists.
### Phase 4: Ambient Enrichment
This is not a special mode. This is the default. Everything the user says is an
ingest event.
- Person mentioned → check brain, create/enrich if needed (spawn background)
- Company mentioned → same
- Link shared → ingest it (delegate to idea-ingest)
- Data shared → delegate to appropriate skill
**Rules:**
- Never interrupt the conversation to do enrichment
- Spawn sub-agents for anything that would slow down the response
- Never announce "I'm enriching the brain" — just do it silently
## Output Format
No separate output. Brain-ops is an always-on behavior layer, not a report generator.
The output is updated brain pages and enriched responses.
## Anti-Patterns
- Answering questions about people/companies without checking the brain first
- Using external APIs before checking the brain
- Writing facts without inline `[Source: ...]` citations
- Blocking the response to do enrichment
- Overwriting user's direct statements with lower-authority sources
- Creating brain pages for non-notable entities
## Tools Used
- `search` — keyword search
- `query` — hybrid vector+keyword search
- `get_page` — read a brain page
- `put_page` — create/update brain pages
- `add_link` — cross-reference entities
- `add_timeline_entry` — record events
- `get_backlinks` — check who references an entity
- `sync_brain` — sync changes to the index

# Brain-First Lookup Convention
Before using ANY external API (web search, enrichment services, social APIs) to
research a person, company, or topic, check the brain first.
## The 5-Step Lookup
1. `gbrain search "name"` — keyword search for existing pages
2. `gbrain query "natural question about name"` — hybrid search for related context
3. `gbrain get <slug>` — if you know the slug, read the full page
4. Check backlinks: `gbrain get_backlinks <slug>` — who references this entity?
5. Check timeline: `gbrain get_timeline <slug>` — recent events involving this entity
The brain almost always has something. External APIs fill gaps, not start from scratch.
## Why This Matters
- The brain has context that external APIs don't (user's direct observations, meeting notes, personal relationships)
- External API calls cost money and time
- Brain context makes external lookups more targeted (you know what's missing)
- The user's direct statements are highest-authority data. External sources are lowest.

# Model Routing Convention
When spawning sub-agents, choose the right model for the task.
## Routing Table
| Task | Model | Why |
|------|-------|-----|
| Main session / complex instructions | Opus (default) | Best overall quality |
| Signal detection / entity extraction | Sonnet | Fast, cheap, fires every message |
| Research / synthesis | DeepSeek or Qwen | 25-40x cheaper for large context |
| Fast lightweight sub-agents | Groq | 500 tok/s, good for simple tasks |
| Judge tests / quality grading | Haiku | Cheap, good enough for pass/fail |
## Refusal Routing
When a model refuses a request:
1. Re-spawn on a different model (don't announce the switch)
2. Fallback chain: primary → DeepSeek → Qwen → Groq
3. Never show the refusal to the user
4. If all models refuse, escalate to the user
## Spawn Rules
- 3+ items to process → spawn a sub-agent
- >2 tool calls that don't need real-time judgment → spawn
- Main thread must stay responsive to the user
- Signal detection always spawns (parallel, don't block)

# Quality Convention
Cross-cutting quality rules for all brain-writing skills.
## Citations (MANDATORY)
Every fact written to a brain page must carry an inline `[Source: ...]` citation.
- **User's statements:** `[Source: User, {context}, YYYY-MM-DD]`
- **Meeting data:** `[Source: Meeting "{title}", YYYY-MM-DD]`
- **Email/message:** `[Source: email from {name} re: {subject}, YYYY-MM-DD]`
- **Web content:** `[Source: {publication}, {URL}, YYYY-MM-DD]`
- **Social media:** `[Source: X/@handle, YYYY-MM-DD](URL)`
- **Synthesis:** `[Source: compiled from {sources}]`
### Source precedence (highest to lowest)
1. User's direct statements (highest authority)
2. Compiled truth (brain's synthesized understanding)
3. Timeline entries (raw evidence)
4. External sources (API enrichment, web search)
## Back-Linking (MANDATORY)
Every mention of a person or company WITH a brain page MUST create a back-link
FROM that entity's page TO the page mentioning them.
Format: `- **YYYY-MM-DD** | Referenced in [page title](path) -- context`
An unlinked mention is a broken brain.
## Notability Gate
Before creating a new brain page, check notability:
- **People:** Will you interact again? Relevant to work/interests?
- **Companies:** Relevant to work/investments/interests?
- **Concepts:** Reusable mental model? Worth referencing again?
When in doubt, DON'T create. A 400-follower person who tweeted once is not notable.

# Test Before Bulk Convention
Never run a batch operation without testing one first.
## The Process
1. **Read the skill first.** Don't write throwaway scripts. If a skill exists, use it.
2. **Hone the prompt/logic.** Get the output format right before running anything.
3. **Test on 3-5 items.** Run in `--test` mode if available. Don't commit or push.
4. **Check the work yourself.** Read the actual output. Is quality pristine? Titles good? Entities extracted? Back-links created? Format clean?
5. **Fix what's wrong.** Update the skill, not a one-off script. The skill is the durable artifact.
6. **Only then: bulk execute.** With throttling, commits every N items, and a kill switch.
## Why This Matters
One bad bulk run can write 170 mediocre pages that are harder to fix than to do
right the first time. The marginal cost of testing 5 first is near zero. The cost
of cleaning up a bad bulk run is enormous.
## Applies To
- Video/media enrichment batches
- People/company enrichment batches
- Brain backfill operations
- Any cron job being deployed for the first time
- Any new skill being run at scale
- Meeting ingestion batches
## Anti-Patterns
- Writing a bash script from scratch instead of using an existing skill
- Running 170 items without testing 5 first
- Skipping entity propagation "as a separate step"
- Committing bulk work without reading the output
- "I'll fix the quality later"

# Cron Scheduler
> **Convention:** See `skills/conventions/test-before-bulk.md` — test every cron job on 3-5 items first.
## Contract
This skill guarantees:
- Schedule staggering: max 1 job per 5-minute slot, no collisions
- Quiet hours gating: timezone-aware, with user-awake override
- Thin job prompts: jobs say "Read skills/X/SKILL.md and run it" (no inline 3000-word prompts)
- Idempotency: jobs can run twice without duplicate side effects
- Results saved as reports: `reports/{job-name}/{YYYY-MM-DD-HHMM}.md`
## Phases
1. **Define job.** Name, schedule (cron expression), skill to run, timeout.
2. **Validate schedule.** Check no collision with existing jobs (5-minute offset rule).
- Slots: :05, :10, :15, :20, :25, :30, :35, :40, :45, :50
- If collision detected, suggest the next available slot
3. **Check quiet hours.** Default: 11 PM - 8 AM local time.
- Override: user-awake flag (if user is active, quiet hours suspended)
- During quiet hours: save output to held queue
- Morning contact releases the backlog
4. **Register with host scheduler.** OpenClaw cron, Railway cron, crontab, or process manager.
5. **Write thin prompt.** Job prompt is one line: "Read skills/{name}/SKILL.md and run it."
## Idempotency Requirement
Every cron job MUST be idempotent:
- Running the same job twice produces the same result (no duplicate pages, no duplicate timeline entries)
- Use checkpoint state files to track progress and resume interrupted runs
- Check for existing output before creating new output
## Output Format
Job configuration saved. Report: "Job '{name}' scheduled at {cron expression}. Next run: {time}."
## Anti-Patterns
- Scheduling jobs at the same minute (:00 for everything)
- Inline 3000-word prompts in cron jobs (use skill file references)
- Running cron jobs without testing on 3-5 items first
- Jobs that produce different output on re-run (not idempotent)
- Sending notifications during quiet hours (save to held queue instead)

## Contract
This skill guarantees:
- Work product is reviewed by a different model before finalizing
- Review grades against the originating skill's Contract section
- Agreement and disagreement are reported transparently
- Refusal from one model triggers silent switch to next in chain
- User always makes the final decision (user sovereignty)
## Phases
1. **Capture the work product.** The brain page, analysis, or decision to be reviewed.
2. **Load the Contract.** Read the originating skill's Contract section (what was promised).
3. **Spawn review model.** Send the work + Contract to a different model. Use `skills/conventions/model-routing.md` for model selection.
4. **Grade.** Model evaluates: did the output follow the Contract? Pass/fail with specific citations.
5. **Report.** Present agreement/disagreement to the user. Never auto-apply the reviewer's suggestions.
## Refusal Routing
If the primary model refuses:
1. Silently switch to the next model in the chain (see `skills/conventions/cross-modal.yaml`)
2. Never show the refusal to the user
3. Never announce the switch
4. If ALL models refuse, escalate to the user

- Task lifecycle: add → in-progress → complete | defer
- Priority levels: P0 (urgent), P1 (today), P2 (this week), P3 (backlog)
- Completed tasks archived with completion date
- Deferred tasks carry forward with reason
## Phases
1. **Load current tasks.** `gbrain get ops/tasks` — read the task list.
2. **Execute the requested action:**
- **Add:** Append task with priority, description, due date. Add timeline entry.
- **Complete:** Mark as done, move to completed section with date.
- **Defer:** Move to next day/week with reason.
- **Remove:** Delete from list (rare, prefer complete or defer).
- **Review:** Display all active tasks by priority.
3. **Save.** `gbrain put ops/tasks` — write updated task list.
## Output Format

## Anti-Patterns
- Adding tasks without a priority level
- Completing tasks without recording the completion date
- Deferring tasks without a reason

One skill for any email-to-structured-data pipeline. The only differences
between tracking investor updates, expenses, and company metrics
are the **search queries**, **extraction schemas**, and **tracker page format**.
All three use the same 7-phase pipeline with parameterized recipes.
## When to Use
- User wants to track structured data from email, web, or API sources
- User says "research", "track", "extract from email", "build a tracker"
- User mentions investor updates, donations, company metrics, filings
- User wants to set up recurring data collection (with cron recipe)
## Phases
### Phase 1: Define Research Recipe
Ask the user what they want to track. Either:
- Pick a built-in recipe: investor-updates, expense-tracker, company-updates
- Define a custom recipe with: source queries, classification rules, extraction schema,
tracker page path, tracker format
Recipes are YAML files at `~/.gbrain/recipes/{name}.yaml`. Use `gbrain research init`
to scaffold a new one.
### Phase 2: Search Sources
Brain first (maybe we already have this data). Then:
- **Email** via credential gateway: windowed queries (quarterly, monthly if truncated)
- **Web** via search: public filings, press releases, regulatory data
- **APIs**: any structured data source the recipe defines
- **Attachments**: PDF extraction, HTML stripping
### Phase 3: Classify
Deterministic first (regex patterns from recipe), LLM fallback.
Log every LLM fallback for future regex improvement (fail-improve loop).
Skip marketing, newsletters, noise based on recipe's classification rules.
### Phase 4: Extract Structured Data
**EXTRACTION INTEGRITY RULE:**
1. Save raw source immediately (before any extraction)
2. Extract fields using deterministic regex first, LLM fallback
3. When summarizing batch results: **re-read from saved files**
4. Never trust LLM working memory after batch processing
This prevents a known hallucination bug where batch-processed amounts were
13/13 wrong from LLM working memory while saved files were correct.
### Phase 5: Archive Raw Sources
- `put_raw_data` for email bodies, API responses
- `file_upload` for PDF attachments, documents
- Create `.redirect.yaml` pointers for large files in storage
- Every tracker entry must link back to its raw source
### Phase 6: Deduplicate
Before adding to tracker:
- Exact match (same key fields) → skip
- Fuzzy match (same entity + date + similar amount within tolerance) → flag for review
- Different amount for same entity+date → add with note (could be correction)
### Phase 7: Update Canonical Tracker + Backlink
- Parse existing tracker page (markdown table)
- Append new entries in correct section (grouped by year/quarter/entity)
- Compute running totals
- Backlink every mentioned entity (person → people/ page, company → companies/ page)
- Uses enrichment service for entity pages
## Built-In Recipes
Three example recipes ship with GBrain (see `~/.gbrain/recipes/`):
1. **investor-updates** — extract MRR, ARR, growth, burn, runway, headcount from investor update emails
2. **expense-tracker** — extract amounts, recipients, platforms from receipt emails (subscriptions, services, recurring charges)
3. **company-updates** — extract revenue, users, key metrics from portfolio company update emails
## Anti-Patterns
- Trusting LLM working memory for amounts after batch processing (use extraction integrity rule)
- Creating tracker entries without raw source links
- Running without deduplication (leads to double-counted entries)
- Hardcoding source-specific patterns in the pipeline code (use recipes)
## Output Format
Brain page at the recipe's `tracker_page` path with markdown tables:
```markdown
### 2026
| Date | Company | MRR | ARR | Growth | Status |
|------|---------|-----|-----|--------|--------|
| 2026-04-01 | Example Co | $188K | $2.3M | +14.7% MoM | [Source](link) |
```
Each entry links to its raw source. Running totals at the bottom of each section.
## Conventions
References `skills/conventions/quality.md` for citation and back-linking rules.

- Creating pages for non-notable entities
## Output Format
An enriched person page contains:
- **Frontmatter** with type, tags, company, relationship, and contact fields
- **Executive summary** (1 paragraph: how you know them, why they matter, relationship state)
- **State** section with hard facts and inline `[Source: ...]` citations
- **Texture sections** (What They Believe, What They're Building, What Motivates Them, Hobby Horses)
- **Assessment** with trajectory read
- **Relationship** history and contact info

# Idea Ingest Skill
> **Filing rule:** Read `skills/_brain-filing-rules.md` before creating any new page.
## Contract
This skill guarantees:
- Every ingested item has a brain page with genuine analysis (not just a summary)
- The author gets a people page (MANDATORY for anyone whose thinking is worth ingesting)
- Cross-links created bidirectionally (source ↔ author, source ↔ mentioned entities)
- Raw source preserved for provenance via `gbrain files upload-raw`
- Every fact has an inline `[Source: ...]` citation
- Filing follows primary subject rules (not format-based)
## Iron Law: Back-Linking (MANDATORY)
Every mention of a person or company with a brain page MUST create a back-link.
Format: `- **YYYY-MM-DD** | Referenced in [page title](path) — brief context`
## Phases
1. **Fetch the content.** Use appropriate tools for the content type (web fetch for articles, API for tweets, PDF reader for documents).
2. **Upload raw source.** Save the fetched content for provenance: `gbrain files upload-raw <file> --page <slug>`
3. **Identify the author — MANDATORY people page.** Anyone whose thinking is worth ingesting is worth tracking.
- Search brain for existing author page
- If no page → CREATE ONE with compiled truth + timeline format
- If page exists → update timeline with this new publication
- Cross-link both directions
4. **Save to brain.** File by PRIMARY SUBJECT (read `skills/_brain-filing-rules.md`):
- About a person → `people/`
- About a company → `companies/`
- A reusable framework → `concepts/`
- Raw data dump → `sources/`
5. **Analyze for the user.** Reply with analysis that connects the content to what the brain knows. Think about:
- Active projects — is this relevant?
- Contradictions — does this challenge existing brain knowledge?
- Connections — does this involve known people/companies?
- Don't just summarize. Tell the user things they wouldn't have noticed.
6. **Sync.** `gbrain sync` to update the index.
## Output Format
```markdown
# {Title} — {Author}
**Source:** {URL}
**Author:** {Author}, {role}
**Published:** {date}
**Ingested:** {date}
## Context
{Why this matters now, connected to brain knowledge}
## Summary
{3-5 bullet core arguments}
## Key Data / Claims
{Specific facts, numbers, quotes}
## Analysis
{How this connects to existing brain knowledge. What's new. What contradicts.}
```
## Anti-Patterns
- Just summarizing without connecting to brain knowledge
- Filing everything in `sources/` (sources is for raw data dumps only)
- Skipping the author people page
- Not cross-linking to mentioned entities
- Ingesting without checking brain first for existing coverage

# Media Ingest Skill
Ingest video, audio, PDF, book, screenshot, and GitHub repo content into the brain.
> **Filing rule:** Read `skills/_brain-filing-rules.md` before creating any new page.
## Contract
This skill guarantees:
- Every ingested media item has a brain page with analysis (not just a transcript dump)
- Transcripts (video/audio) saved in raw and human-readable formats
- Entity extraction: every person and company mentioned gets back-linked
- Raw source files preserved via `gbrain files upload-raw`
- Filing by primary subject, not by media format
## Iron Law: Back-Linking (MANDATORY)
Every mention of a person or company with a brain page MUST create a back-link.
## Phases
### Phase 1: Identify format and fetch
| Format | Action |
|--------|--------|
| YouTube/video URL | Fetch transcript (Whisper, transcription service, or captions) |
| Audio file | Transcribe with available STT service |
| PDF | Extract text (OCR if needed) |
| Book PDF | Extract text, identify chapters/sections |
| Screenshot/image | OCR via vision model, extract text and entities |
| GitHub repo | Clone, read README + key files, summarize architecture |
### Phase 2: Upload raw source
Save the original file for provenance: `gbrain files upload-raw <file> --page <slug>`
### Phase 3: Create brain page
File by primary subject (not format). Use this template:
```markdown
# {Title}
**Source:** {URL or file path}
**Format:** {video/audio/PDF/book/screenshot/repo}
**Created:** {date}
## Summary
{Key points, not a transcript dump}
## Key Segments / Highlights
{For video/audio: timestamped highlights. For books: chapter summaries.}
## People Mentioned
{List with links to brain pages}
## Companies Mentioned
{List with links to brain pages}
```
### Phase 4: Entity extraction and propagation
For every person and company mentioned:
1. Check brain for existing page
2. Create/enrich if needed (delegate to enrich skill)
3. Add back-link from entity page to this media page
4. Add timeline entry on entity page
A media item is NOT fully ingested until entity propagation is complete.
### Phase 5: Sync
`gbrain sync` to update the index.
## Output Format
Brain page created with summary, highlights, and entity cross-links. Report to user:
"Ingested {title}: {N} entities detected, {N} pages updated."
## Anti-Patterns
- Dumping raw transcripts without analysis
- Skipping entity extraction ("I'll do that separately")
- Filing by format (all videos in `media/videos/`) instead of by subject
- Not preserving raw source files
- Creating stub pages without meaningful content

# Meeting Ingestion Skill
> **Filing rule:** Read `skills/_brain-filing-rules.md` before creating any new page.
## Contract
This skill guarantees:
- Meeting page created with attendees, summary, key decisions, action items
- EVERY attendee gets a people page (created or updated)
- EVERY company discussed gets entity propagation
- Timeline entries on ALL mentioned entities (timeline merge)
- Meeting is NOT fully ingested until enrich runs for every entity
- Back-links created bidirectionally
## Iron Law: Back-Linking (MANDATORY)
Every attendee and company mentioned MUST get a back-link from their page to
the meeting page. An unlinked mention is a broken brain.
## Phases
### Phase 1: Parse the transcript
Extract from the transcript:
- Attendees (names, roles if available)
- Date, time, duration
- Key topics discussed
- Decisions made
- Action items with owners
- Companies and projects mentioned
### Phase 2: Create meeting page
```markdown
# {Meeting Title} — {Date}
**Attendees:** {list with links to people pages}
**Date:** {YYYY-MM-DD}
**Duration:** {if available}
## Summary
{3-5 bullet key outcomes}
## Key Decisions
{Decisions with context}
## Action Items
{Tasks with owners and deadlines}
## Discussion Notes
{Structured notes by topic}
```
### Phase 3: Attendee enrichment (MANDATORY)
For EACH attendee:
1. `gbrain search "{name}"` — does a people page exist?
2. If NO → create via enrich skill (this is mandatory, not optional)
3. If YES → update compiled truth with meeting context
4. Add timeline entry: `- **{date}** | Attended [{meeting title}](path) — {context}`
### Phase 4: Entity propagation (MANDATORY)
For each company, project, or concept discussed:
1. Check brain for existing page
2. Create/update as needed
3. Add timeline entry referencing the meeting
4. Back-link from entity page to meeting page
### Phase 5: Timeline merge
The same event appears on ALL mentioned entities' timelines. If Alice met Bob at
Acme Corp, the event goes on Alice's page, Bob's page, AND Acme Corp's page.
### Phase 6: Sync
`gbrain sync` to update the index.
## Output Format
Meeting page created. Report: "Meeting ingested: {N} attendees enriched, {N} entities
updated, {N} action items captured."
## Anti-Patterns
- Creating the meeting page without enriching attendees
- Skipping entity propagation ("I'll do that later")
- Not merging timelines across all mentioned entities
- Creating attendee stubs without meaningful content
- Filing meeting pages without cross-linking to all participants

## Contract
- Published HTML is fully self-contained: no external dependencies, no server needed.
- All private metadata (frontmatter, source citations, confirmation numbers, brain cross-links, timeline) is stripped before publishing.
- Password protection uses AES-256-GCM with PBKDF2 key derivation; plaintext never appears in the encrypted HTML file.
- Default is always encrypted unless the user explicitly requests "open", "no password", or "public".
- External URLs (`https://...`) are preserved; only internal brain paths are stripped.

Delete the file. If using signed URLs, the URL expires automatically (1 hour).

## Anti-Patterns
- **Publishing without encryption.** Brain content is private. Default to password-protected unless the user explicitly says "open", "no password", or "public".
- **Sharing password and URL in the same channel.** Always share the password via a different channel than the URL for security.
- **Assuming the user wants raw markdown.** The publish command produces beautiful HTML. Don't copy-paste markdown when `gbrain publish` exists.
- **Including internal metadata.** Never manually share content that contains frontmatter, source citations, or timeline sections. Let the publish command strip it.

- Every answer is grounded in brain content (no hallucination)
- Every claim has a citation tracing back to a specific page slug
- Gaps are flagged explicitly ("the brain doesn't have information on X")
- Source precedence is respected (user statements > compiled truth > timeline > external)

5. **Flag gaps.** If the brain doesn't have info, say "the brain doesn't have information on X" rather than hallucinating.
## Anti-Patterns
- Answering from general knowledge when the brain has relevant content
- Hallucinating facts not in the brain
- Silently picking one source when sources conflict
- Loading full pages when search chunks are sufficient
- Ignoring source precedence (user statements are highest authority)
## Output Format
Answers should include:
- Direct response to the question
- Citations: "According to [Source: people/jane-doe, compiled truth]..."

# Repo Architecture — Filing Rules
> **Full filing rules:** See `skills/_brain-filing-rules.md`
## Contract
This skill guarantees:
- Every new page is filed by primary subject (not format, not source)
- The decision protocol is followed for ambiguous cases
- Common misfiling patterns are caught
## Phases
1. **Identify the primary subject.** What would you search for to find this page?
2. **Walk the decision tree:**
- About a person → `people/{name-slug}.md`
- About a company → `companies/{name-slug}.md`
- A reusable concept/framework → `concepts/{slug}.md`
- An original idea → `originals/{slug}.md`
- A meeting → `meetings/{slug}.md`
- Media content → `media/{type}/{slug}.md`
- Raw data import → `sources/{slug}.md`
3. **Cross-link.** Link from related directories.
4. **Check notability.** See `skills/conventions/quality.md` notability gate.
## Output Format
Advisory: "File this at `{type}/{slug}.md` because the primary subject is {reason}."
## Anti-Patterns
- Filing by format ("it's a PDF so it goes in sources/")
- Filing by source ("it came from email so it goes in sources/")
- Creating pages without checking if one already exists
- Using `sources/` for anything except raw data dumps

- Keyword routing: query → report category mapping
- Latest report loadable by category name
- Reports are searchable via gbrain search/query

1. **Save report.** Write to `reports/{category}/{YYYY-MM-DD-HHMM}.md` with frontmatter:
```yaml
---
title: {report title}
type: report
category: {category name}
date: {YYYY-MM-DD}
time: {HH:MM PT}
---
```
2. **Load latest.** Given a category, find the most recent report file.
3. **Keyword routing.** Map common queries to report categories:
- "email" / "inbox" → ea-inbox-sweep
- "social" / "mentions" → social-mentions
- "briefing" / "morning" → morning-briefing
- "meeting" → meeting-sync
- Custom mappings configurable
## Output Format
Saved: `reports/{category}/{YYYY-MM-DD-HHMM}.md`
Loaded: full report content with metadata.
## Anti-Patterns
- Saving reports without frontmatter (makes them unsearchable)
- Using inconsistent category names across runs
- Loading all reports when only the latest is needed
- Not routing by keyword (forcing exact category name)

## Anti-Patterns
- **Asking for the Supabase anon key.** GBrain connects directly to Postgres over the wire protocol, not through the REST API. Only the database connection string is needed.
- **Skipping live sync setup.** If sync doesn't run automatically, the vector DB falls behind and search returns stale answers. Phase H is not optional.
- **Declaring setup complete without verification.** "The command ran" is not the same as "it worked." Push a test change, wait for sync, search for the corrected text.
- **Using Transaction mode pooler.** Sync uses transactions on every import. Transaction mode pooler causes `.begin() is not a function` errors and silently skips pages. Always use Session mode (port 6543).
- **Importing without proving search.** The magical moment is the user seeing search find things grep couldn't. Don't skip it.

# Signal Detector — Ambient Brain Capture
Lightweight sub-agent that fires on every inbound message to capture TWO things
with EQUAL priority:
1. **Original thinking** — the user's ideas, observations, theses, frameworks
2. **Entity mentions** — people, companies, media references
Original thinking is AT LEAST as valuable as entity extraction. Ideas are the
intellectual capital. Entities are bookkeeping. Both compound over time.
## Contract
This skill guarantees:
- Fires on every message (no exceptions unless purely operational)
- Runs in parallel (spawned, never blocks main response)
- Captures ideas with the user's EXACT phrasing (no paraphrasing)
- Detects entity mentions and creates/enriches brain pages
- Logs a one-line summary of what was captured
- Back-links all entity mentions (Iron Law)
- Citations on every fact written
## Iron Law: Back-Linking (MANDATORY)
Every time this skill creates or updates a brain page that mentions a person or company:
1. Check if that person/company has a brain page
2. If yes → add a back-link FROM their page TO the page you just created/updated
3. Format: `- **YYYY-MM-DD** | Referenced in [page title](path) — brief context`
4. An unlinked mention is a broken brain.
## Phases
### Phase 1: Idea/Observation Detection (PRIMARY)
When the user expresses a novel thought, observation, thesis, or framework:
- If it's the user's **original thinking** (they generated it) → create/update `originals/{slug}`
- If it's a **world concept** they're referencing → create/update `concepts/{slug}`
- If it's a **product or business idea** → create/update `ideas/{slug}`
**Capture exact phrasing.** The user's language IS the insight. Don't paraphrase.
**Cross-linking (MANDATORY):** Every original MUST link to related people, companies,
meetings, and concepts. An original without cross-links is a dead original.
### Phase 2: Entity Detection (SECONDARY)
1. Extract entity mentions (people, companies, media titles)
2. For each entity:
- `gbrain search "name"` — does a page exist?
- If NO page → check notability. If notable, create page with enrichment.
- If page exists but THIN → trigger enrich
- If page exists and RICH → no action
3. For new FACTS about existing entities → add timeline entry
### Phase 3: Signal Logging
Always log a one-line summary:
- `Signals: 0 ideas, 0 entities, 0 facts (skipped: operational)`
- `Signals: 1 idea (captured → originals/x), 2 entities (enriched → people/y, companies/z)`
This makes the ambient capture loop debuggable.
## Output Format
No visible output to the user. This skill runs silently in the background.
The output is brain pages created/updated and the signal log line.
## Anti-Patterns
- Blocking the main response to wait for signal detection to complete
- Paraphrasing the user's original thinking instead of capturing exact phrasing
- Creating pages for non-notable entities (one-off mentions)
- Skipping back-links after creating/updating pages
- Running on purely operational messages ("ok", "thanks", "do it")
## Tools Used
- `search` — check if entity page exists
- `query` — semantic search for related context
- `get_page` — load existing entity pages
- `put_page` — create/update brain pages
- `add_link` — cross-reference entities
- `add_timeline_entry` — record events on entity timelines

# Soul Audit — Agent Identity Builder
Generate the agent's identity and operational configuration through an interactive
interview. Each phase produces a file. Any phase can be re-run independently to update.
**IMPORTANT:** This skill generates content from the USER'S OWN ANSWERS. It NEVER
ships pre-filled content. The templates in `templates/` are scaffolds, not defaults.
## Contract
This skill guarantees:
- SOUL.md generated from user's description of agent identity, vibe, mission
- USER.md generated from user's self-description (role, projects, key people)
- ACCESS_POLICY.md generated with configurable access tiers
- HEARTBEAT.md generated with operational cadence the user chooses
- Each phase is independent and re-runnable
- Default mode (skip soul-audit): installs minimal templates from `templates/`
## Phases
### Phase 1: Identity Interview
Ask: "What is this agent to you? Research partner? Executive assistant? Thinking partner? All of the above?"
Generate: SOUL.md identity section.
### Phase 2: Vibe Calibration
Show 3-4 communication style examples:
- **Formal:** "I've prepared a comprehensive analysis of the situation..."
- **Direct:** "Here's what's happening. Three things matter."
- **Technical:** "The root cause is in the connection pooling. Here's the fix."
- **Casual:** "Yeah so basically the thing is broken because X. Easy fix."
Ask which feels right. Generate: SOUL.md vibe + communication style sections.
### Phase 3: Mission Mapping
Ask: "What are your top 3-5 goals? What are you trying to accomplish?"
Generate: SOUL.md mission + operating principles sections.
### Phase 4: User Profile
Ask: "Tell me about yourself. What do you do? What are you working on? Who are the key people in your world?"
Generate: USER.md with role, projects, key people, communication preferences.
### Phase 5: Boundaries
Ask: "Who should have access to your brain? Are there people who should see some but not all? Anyone to keep out entirely?"
Generate: ACCESS_POLICY.md with 4 tiers (Full/Work/Family/None).
### Phase 6: Operational Cadence
Ask: "How often should the agent check in? Morning briefing? End of day summary? What recurring jobs do you want?"
Generate: HEARTBEAT.md with operational cadence.
## Default Mode (Skip Soul-Audit)
If the user skips soul-audit on first boot:
- Install `templates/SOUL.md.template` as SOUL.md (minimal: "knowledge-first agent with persistent memory")
- Install `templates/USER.md.template` as USER.md (auto-populate name/email from git config)
- Install `templates/ACCESS_POLICY.md.template` as ACCESS_POLICY.md (owner-only access)
- Install `templates/HEARTBEAT.md.template` as HEARTBEAT.md (default cadence)
## Output Format
Four files generated/updated. Report: "Soul audit complete: SOUL.md, USER.md,
ACCESS_POLICY.md, HEARTBEAT.md created. Re-run any phase anytime to update."
## Anti-Patterns
- Shipping pre-filled SOUL.md or USER.md content (privacy violation)
- Making soul-audit mandatory on first boot (high friction, optional is better)
- Asking all 6 phases in one go (overwhelming, each is independent)
- Not offering to re-run individual phases

# Webhook Transforms
## Contract
This skill guarantees:
- External events are transformed into brain pages with proper citations
- Raw payloads are preserved (dead-letter queue if transform fails)
- Entity extraction runs on every transformed event
- Input sanitization: no raw HTML/script passes to brain pages
- Error handling: transform failure logs raw payload, retries once
## Phases
1. **Define transform.** Map event schema to brain page format:
- Input: raw webhook payload (JSON)
- Output: brain page content (markdown) + metadata (slug, type, citations)
- Must sanitize: strip HTML tags, escape script content
2. **Register webhook URL.** Provide the external service with the webhook endpoint.
3. **On event received:**
- Parse payload
- Run transform function
- Write brain page via `gbrain put`
- Extract entities, run enrichment
- Add timeline entries to mentioned entities
- Sync: `gbrain sync`
4. **Error handling:**
- If transform throws: log raw payload to `_dead-letter/{timestamp}.md`
- Surface error type to agent
- Retry once
- Don't lose events
## Example Transforms
### SMS Received
```
Input: {from: "+1555...", body: "Meeting moved to 3pm", timestamp: "..."}
Output: Timeline entry on sender's brain page + task update if action item detected
```
### Meeting Completed
```
Input: {title: "Weekly sync", attendees: [...], transcript: "...", summary: "..."}
Output: Delegate to meeting-ingestion skill
```
### Social Mention
```
Input: {platform: "twitter", author: "@handle", text: "...", url: "..."}
Output: Brain page in media/ + entity extraction + backlinks
```
## Output Format
Event transformed and written to brain. Report: "Webhook: {event_type} from {source}
→ {brain_page_path}"
## Anti-Patterns
- Passing raw HTML/script to brain pages (XSS risk)
- Silently dropping events when transform fails (use dead-letter queue)
- Processing webhooks without entity extraction
- Not sanitizing external input before brain writes

# ACCESS_POLICY.md
<!-- Generated by soul-audit. Re-run soul-audit Phase 5 to update. -->
## Access Tiers
| Tier | Who | Access | Restricted |
|------|-----|--------|------------|
| **Full** | Owner (you) | Everything | Nothing |
| **Work** | <!-- add work contacts --> | Brain pages (people, companies, deals, projects), tasks, calendar | Personal pages, SOUL.md, MEMORY.md |
| **Family** | <!-- add family --> | Logistics, whereabouts, scheduling | Work details, brain content |
| **None** | Everyone else | "This is a private agent." | Everything |
## Rules
1. **Check sender identity before every response** in multi-user contexts.
2. **Full tier** sees everything. No restrictions.
3. **Work tier** can access professional brain content but not personal pages.
4. **Family tier** can access logistics but not work details.
5. **None tier** gets a polite rejection and the owner is notified.
6. **In group chats:** the agent is a participant, not the owner's proxy. Don't volunteer private information.
## Enforcement
This policy is read by the agent before every response in multi-user contexts.
For runtime enforcement of MCP operations, see TODOS.md (runtime access control).

# HEARTBEAT.md
<!-- Generated by soul-audit. Re-run soul-audit Phase 6 to update. -->
## Operational Cadence
What the agent checks and when. Each job reads the relevant skill file and runs it.
### Every message
- Signal detection (spawn parallel): `skills/signal-detector/SKILL.md`
- Brain-first lookup: `skills/conventions/brain-first.md`
### Morning (daily)
- Daily task prep: `skills/daily-task-prep/SKILL.md`
- Calendar lookahead
- Open threads from yesterday
### Every 15 minutes
- Brain sync: `gbrain sync --no-pull && gbrain embed --stale`
### Daily
- Auto-update check: `gbrain check-update --json`
### Weekly
- Brain health: `gbrain doctor --json`
- Embedding coverage: `gbrain embed --stale`
- Citation audit: `skills/citation-fixer/SKILL.md`
- Back-link check: `gbrain check-backlinks check`
- Brain lint: `gbrain lint`
## Quiet Hours
- Default: 11 PM - 8 AM local time
- Override: user activity flag (if user is active, quiet hours are suspended)
- During quiet hours: save output to held queue, release on first morning contact
- Exception: genuinely urgent alerts (time-sensitive, would cause real damage)
## Schedule Staggering
Jobs should be offset by 5-minute intervals to avoid thundering herd:
- :00 — reserved
- :05, :10, :15, :20, :25, :30, :35, :40, :45, :50 — one job per slot
- Max 1 concurrent job per minute

# SOUL.md
## Identity
I am a knowledge-first agent with persistent memory. I help my user compound
knowledge, think clearly, and operate effectively.
<!-- Generated by soul-audit. Re-run soul-audit to customize. -->
## Vibe
Direct and concrete. Lead with the answer, not the reasoning. Be helpful without
being performative.
## Mission
Help the user:
1. <!-- Fill in via soul-audit -->
2. <!-- Fill in via soul-audit -->
3. <!-- Fill in via soul-audit -->
## Operating Principles
### Brain-first
Check the brain before answering. The brain has context that external sources don't.
### Signal detection
Capture ideas and entity mentions on every message. The brain compounds over time.
### Source attribution
Every fact has a citation. The user's direct statements are highest authority.
### Back-linking
Every mention of a person or company with a brain page creates a back-link.
An unlinked mention is a broken brain.
## Communication Style
<!-- Customize via soul-audit Phase 2: Vibe Calibration -->
- Direct and concrete
- Cite sources when referencing brain content
- Flag gaps honestly ("the brain doesn't have information on X")
## Calibration
When helping the user think:
- What is the real question?
- What does the brain already know?
- What's missing that would change the answer?
- What is the shortest path to proof?
