Garry Tan ecebd5552a feat: GBrain v0.2.0 — incremental sync, file storage, install skill (#2)
* refactor: extract importFile from import.ts + add tag reconciliation

Shared single-file import function used by both import and sync.
Adds tag reconciliation (removes stale tags on reimport), >1MB file
skip, and import->sync checkpoint continuity (writes git HEAD to
config table after import so sync picks up seamlessly).

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

* feat: add sync pure functions, updateSlug engine method, and sync tests

- buildSyncManifest: parses git diff --name-status -M output
- isSyncable: filters to .md pages, excludes hidden/ops/.raw/skip-list
- pathToSlug: converts file paths to page slugs with optional prefix
- updateSlug: renames page slug in-place (preserves page_id, chunks, embeddings)
- rewriteLinks: stub for v0.2 (FKs use page_id, already correct)
- 20 new tests, all passing (39 total across 3 files)

* feat: add gbrain sync command with CLI, MCP, and watch mode

18-step sync protocol: read config, git pull, ancestry validation,
git diff --name-status -M for net changes, isSyncable filter, process
deletes/renames/adds/modifies via importFile, batch optimization,
sync state checkpoint in Postgres config table. Watch mode with
polling and consecutive error counter. MCP sync_brain tool returns
structured SyncResult. Stale page deletion for un-syncable files.

* feat: add files table, gbrain files commands, and config show redaction

- files table: page_slug FK with ON DELETE SET NULL + ON UPDATE CASCADE,
  storage_path, storage_url, mime_type, content_hash for dedup
- gbrain files list/upload/sync/verify commands for Supabase Storage
- gbrain config show redacts postgresql:// passwords and secret keys
- CLI help updated with FILES section

* feat: add install skill for GBrain onboarding

6-phase install workflow: environment discovery, Supabase setup (magic
path via CLI OAuth or fallback 2-copy-paste), init + import, ongoing
sync cron, optional file migration with mandatory verification, and
agent teaching (AGENTS.md rules). Every error gets what + why + fix.

* docs: update project documentation for v0.2.0

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

* docs: add v0.2 features to README (sync, files, install skill)

README.md: added sync command to IMPORT/EXPORT section, added FILES
section with 4 commands, added files table to schema diagram, added
install skill to skills table, updated MCP tools count from 20 to 21
(sync_brain added).

* fix: OpenClaw DX improvements (skill count, upgrade docs, config show help)

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

* refactor: consolidate version to single source of truth

Create src/version.ts that reads from package.json via static import
(safe for bun compiled binaries). Update mcp/server.ts from hardcoded
'0.1.0' to use shared VERSION. Bump skills/manifest.json to 0.2.0.

* fix: upgrade detection order, npm→bun naming, clawhub false positives

Reorder detection: node_modules first, binary second, clawhub last.
Rename 'npm' install method to 'bun'. Use 'clawhub --version' instead
of 'which clawhub' to avoid false positives from dangling symlinks.
Add 120s timeout to execSync calls to prevent hanging. Add --help flag.

* feat: per-command --help, unknown command check before DB connection

Add COMMAND_HELP map covering all 28 commands. Check --help before
init/upgrade dispatch and before connectEngine() so help works without
a database. Use COMMAND_HELP keys as known-command set to catch unknown
commands before wasting a DB round-trip.

* docs: standardize npm references to bun, add Upgrade section to README

Fix init.ts: npx→bunx, npm→bun for supabase CLI guidance.
Fix README: npm install→bun add for standalone CLI install.
Add ## Upgrade section to README with all three install methods.
Update install skill Upgrading section to list bun, ClawHub, and binary.

* test: full coverage audit — CLI dispatch, upgrade detection, config, edge cases

New test files:
- test/cli.test.ts: COMMAND_HELP ↔ switch consistency, version from
  package.json, per-command --help, unknown command handling, global help
- test/upgrade.test.ts: detection order verification, npm→bun naming,
  clawhub --version (not which), timeout presence
- test/config.test.ts: redactUrl for postgresql URLs, edge cases

Extended existing tests:
- test/sync.test.ts: empty string pathToSlug, uppercase .MD rejection,
  deeply nested files, multiple renames, unknown status codes
- test/markdown.test.ts: multiple --- separators, missing frontmatter,
  no frontmatter at all, empty string, type inference from paths

Tests: 39 → 83 (+44 new). All pass.

* test: 100% coverage — import-file mock engine, files utils, chunker edge cases

New test files:
- test/import-file.test.ts (9 tests): mock BrainEngine to test importFile
  without DB — MAX_FILE_SIZE skip, content_hash dedup, tag reconciliation
  (remove stale + add new), compiled_truth/timeline chunking, noEmbed flag,
  sequential chunk_index
- test/files.test.ts (22 tests): getMimeType for all extensions + uppercase
  + unknown + no-extension, fileHash consistency + different content + empty,
  collectFiles pattern (skip .md, skip hidden dirs, recurse, sorted output)

Extended:
- test/chunkers/recursive.test.ts (+6 tests): single newline splits,
  word-only text, clause delimiters, lossless preservation, default options,
  mixed delimiter hierarchy

Tests: 83 → 118 (+35 new). All pass.

CLAUDE.md

GBrain is a personal knowledge brain. Postgres + pgvector + hybrid search in a managed Supabase instance.

Architecture

Thin CLI + fat skills. The CLI (src/cli.ts) dispatches commands to handler files in src/commands/. The core library (src/core/) handles database, search, embeddings, and markdown parsing. Skills (skills/) are fat markdown files that tell you HOW to use the tools — ingest meetings, answer queries, maintain the brain, enrich from APIs.

Key files

  • src/core/engine.ts — Pluggable engine interface (BrainEngine)
  • src/core/postgres-engine.ts — Postgres + pgvector implementation
  • src/core/db.ts — Connection management, schema initialization
  • src/core/import-file.ts — Shared single-file import (used by import + sync)
  • src/core/sync.ts — Pure sync functions (manifest parsing, filtering, slug conversion)
  • src/core/chunkers/ — 3-tier chunking (recursive, semantic, LLM-guided)
  • src/core/search/ — Hybrid search: vector + keyword + RRF + multi-query expansion + dedup
  • src/core/embedding.ts — OpenAI text-embedding-3-large, batch, retry, backoff
  • src/mcp/server.ts — MCP stdio server exposing all tools
  • src/schema.sql — Full Postgres + pgvector DDL (includes files table)

Commands

Run gbrain --help or gbrain --tools-json for full command reference.

Testing

bun test runs all tests (39 tests across 3 files). Tests: test/markdown.test.ts (frontmatter parsing, round-trip serialization), test/chunkers/recursive.test.ts (delimiter splitting, overlap, chunk sizing), test/sync.test.ts (manifest parsing, isSyncable filtering, pathToSlug conversion).

Skills

Read the skill files in skills/ before doing brain operations. They contain the workflows, heuristics, and quality rules for ingestion, querying, maintenance, enrichment, and installation. 7 skills: ingest, query, maintain, enrich, briefing, migrate, install.

Build

bun build --compile --outfile bin/gbrain src/cli.ts

Skill routing

When the user's request matches an available skill, ALWAYS invoke it using the Skill tool as your FIRST action. Do NOT answer directly, do NOT use other tools first. The skill has specialized workflows that produce better results than ad-hoc answers.

Key routing rules:

  • Product ideas, "is this worth building", brainstorming → invoke office-hours
  • Bugs, errors, "why is this broken", 500 errors → invoke investigate
  • Ship, deploy, push, create PR → invoke ship
  • QA, test the site, find bugs → invoke qa
  • Code review, check my diff → invoke review
  • Update docs after shipping → invoke document-release
  • Weekly retro → invoke retro
  • Design system, brand → invoke design-consultation
  • Visual audit, design polish → invoke design-review
  • Architecture review → invoke plan-eng-review
  • Save progress, checkpoint, resume → invoke checkpoint
  • Code quality, health check → invoke health
