Garry Tan baf3517868 feat: v0.9.0 -- smart file storage, publish, production-grade skills (#62)
* feat: battle-tested skill patterns from production deployment

Backport production-learned brain-operations patterns:
- Iron Law of Back-Linking (mandatory bidirectional linking)
- Brain filing rules (file by primary subject, not format)
- Enrichment protocol (7-step pipeline, 3-tier system, person/company templates)
- Media ingest workflows (articles, videos, podcasts, PDFs, screenshots)
- Citation requirements (mandatory [Source: ...] on every fact)
- Test Before Bulk operating principle
- Voice recipe: unicode crash fix, PII scrub, identity-first prompt, DIY STT+LLM+TTS
- X-to-Brain recipe: image OCR, Filtered Stream, tweet rating rubric, cron stagger

* chore: bump version and changelog (v0.8.1)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: add _brain-filing-rules.md to CLAUDE.md key files

* feat: smart file upload with TUS resumable and .redirect.yaml pointers

- Supabase Storage auto-selects upload method by file size:
  < 100 MB standard POST, >= 100 MB TUS resumable (6 MB chunks + retry)
- Signed URL generation for private bucket access (1-hour expiry)
- New `upload-raw` command with size routing: small text stays in git,
  large/media files go to cloud with .redirect.yaml pointer
- New `signed-url` command for generating access links
- File resolver supports both .redirect.yaml (v0.9+) and .redirect (legacy)
- Redirect format upgraded: 10 fields with full metadata
- All migration commands (mirror, redirect, restore, clean) handle both formats

* feat: skills reference actual gbrain file commands

- Filing rules document upload-raw, signed-url, and .redirect.yaml format
- Ingest skill uses gbrain files upload-raw for raw source preservation
- Maintain skill adds file storage health checks
- Setup skill adds storage configuration phase with migration guidance
- Voice recipe uses upload-raw for call audio storage
- Migration v0.9.0 with complete storage setup instructions

* chore: bump version and changelog (v0.9.0)

* feat: gbrain publish -- shareable HTML with password protection

First code+skill pair: deterministic code does the work (strip private data,
encrypt with AES-256-GCM, generate self-contained HTML), the skill tells the
agent when and how to use it. 34 new tests.

See: https://x.com/garrytan/status/2042925773300908103

* feat: backlinks check/fix, page lint, and report commands

Three new deterministic tools (zero LLM calls):

- gbrain backlinks check/fix -- scans brain for entity mentions without
  back-links, creates them. Enforces the Iron Law from the skills.
- gbrain lint [--fix] -- catches LLM preambles, code fence wrapping,
  placeholder dates, missing frontmatter, broken citations, empty sections.
  --fix auto-strips fixable artifacts.
- gbrain report --type <name> -- saves timestamped reports to
  brain/reports/{type}/YYYY-MM-DD-HHMM.md for audit trails.

33 new tests (409 total, 0 fail).

* feat: v0.9.0 migration tells agents to swap scripts for built-in commands

Migration file now:
- Lists all 5 new deterministic commands with usage examples
- Includes a script-to-command replacement table (old -> new)
- Tells the agent to find custom script references in AGENTS.md,
  skills, and cron jobs and replace with gbrain commands
- Adds recommended cron jobs for daily backlink fix + weekly lint
- References the Thin Harness, Fat Skills thread

* fix: CLI routing bugs found during DX review

- Fixed subArgs reference error in handleCliOnly (used wrong variable name)
- Renamed gbrain backlinks check/fix to gbrain check-backlinks to avoid
  conflict with existing backlinks operation (per-page incoming links)
- Added TOOLS section to --help output showing publish, check-backlinks,
  lint, report
- Added upload-raw and signed-url to FILES section in --help
- Updated all docs/migration references to use check-backlinks

* fix: security hardening from adversarial review

- XSS: sanitize marked.parse() output (strip script/iframe/on* attrs)
- Path traversal: validate report --type against [a-z0-9-] pattern
- TUS: HEAD request before retry to get server's actual offset (TUS spec)
- Pointer: upload-raw now includes pointer content in JSON output
- Symlinks: use lstatSync in all walkers to prevent directory escape

# Query Skill
Answer questions using the brain's knowledge with 3-layer search and synthesis.
## Workflow
1. **Decompose the question** into search strategies:
- Keyword search for specific names, dates, terms
- Semantic query for conceptual questions
- Structured queries (list by type, backlinks) for relational questions
2. **Execute searches:**
- Keyword search gbrain for FTS matches (search)
- Hybrid search gbrain for semantic+keyword with expansion (query)
- List pages in gbrain by type or check backlinks for structural queries
3. **Read top results.** Read the top 3-5 pages from gbrain to get full context.
4. **Synthesize answer** with citations. Every claim traces back to a specific page slug.
5. **Flag gaps.** If the brain doesn't have info, say "the brain doesn't have information on X" rather than hallucinating.
## Quality Rules
- Never hallucinate. Only answer from brain content.
- Cite sources: "According to concepts/do-things-that-dont-scale..."
- Flag stale results: if a search result shows [STALE], note that the info may be outdated
- For "who" questions, use backlinks and typed links to find connections
- For "what happened" questions, use timeline entries
- For "what do we know" questions, read compiled_truth directly
## Token-Budget Awareness
Search returns **chunks**, not full pages. Read the excerpts first before deciding
whether to load a full page.
- `gbrain search` / `gbrain query` return ranked chunks with context snippets.
These are often enough to answer the question directly.
- Only use `gbrain get <slug>` to load the full page when a chunk confirms the
page is relevant and you need more context (e.g., compiled truth, timeline).
- **"Tell me about X"** -- get the full page (the user wants the complete picture).
- **"Did anyone mention Y?"** -- search results are enough (the user wants a yes/no with evidence).
### Source precedence
When multiple sources provide conflicting information, follow this precedence:
1. **User's direct statements** (highest authority -- what the user told you directly)
2. **Compiled truth** (the brain's synthesized, cited understanding)
3. **Timeline entries** (raw evidence, reverse-chronological)
4. **External sources** (web search, API enrichment -- lowest authority)
When sources conflict, note the contradiction with both citations. Don't silently
pick one.
## Citation in Answers
When referencing brain pages in your answer, propagate inline citations:
- Cite the page: "According to [Source: people/jane-doe, compiled truth]..."
- When brain pages have inline `[Source: ...]` citations, propagate them so
the user can trace facts to their origin
- When you synthesize across multiple pages, cite all sources
## Search Quality Awareness
If search results seem off (wrong results, missing known pages, irrelevant hits):
- Run `gbrain doctor --json` to check index health
- Check embedding coverage -- partial embeddings degrade hybrid search
- Compare keyword search (`gbrain search`) vs hybrid search (`gbrain query`)
for the same query to isolate whether the issue is embedding-related
- Report search quality issues in the maintain workflow (see maintain skill)
## Tools Used
- Keyword search gbrain (search)
- Hybrid search gbrain (query)
- Read a page from gbrain (get_page)
- List pages in gbrain with filters (list_pages)
- Check backlinks in gbrain (get_backlinks)
- Traverse the link graph in gbrain (traverse_graph)
- View timeline entries in gbrain (get_timeline)
