/brain-wiki — CoCo Knowledge Articles

Browse, search, and generate Wikipedia-quality articles about people, systems, teams, and org units across all CoCo brain DB projects.

Articles are auto-generated from the brain DB by the daily knowledge engine cron (`~/.coco/knowledge/cron.py`). Each article synthesizes all evidence available about an entity — decisions, events, relationships, tasks — into a structured, versioned knowledge artifact.

Commands

`/brain-wiki [entity]` — Show article (or list all)

**With entity name:** Look up and display a knowledge article.

python3 ~/.claude/skills/brain/scripts/brain/brain_cli.py wiki --name "{entity}"

Display format:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
{Title}                                    [{type}]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Infobox:  Projects: {list} | Role: {role} | Team: {team}

{Summary paragraph}

## Role
{content}

## Relationships
{content}

## Timeline
{content}

## Decisions
{content}

## Open Questions
{content}

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Generated: {date}  ·  Confidence: {0-100}%  ·  Sources: N chunks
GID: {uuid}  ·  v{version}

If article not found → run wiki-search with the entity name as query and show top 3 candidates:

No article found for "{entity}". Did you mean:
  1. {title}  ({confidence}%)  — /brain-wiki {gid}
  2. {title}  ({confidence}%)
  3. {title}  ({confidence}%)

Warnings to show inline:

• If confidence < 30%: `⚠ Low confidence — this article needs more source data. Run /brain-update after adding more context.`
• If pending merge proposals exist for this entity: `ℹ Possible duplicate: matches "{other_name}" ({similarity}%) — run /brain-wiki review-merges to resolve`

**Without entity name:** List all available articles.

python3 ~/.claude/skills/brain/scripts/brain/brain_cli.py wiki-search "*" --limit 50

Display as table:

`/brain-wiki search <query>` — Unified FTS5 + semantic search

python3 ~/.claude/skills/brain/scripts/brain/brain_cli.py wiki-search "{query}"

Runs both FTS5 keyword search and MemPalace semantic search, merges via RRF.

Display format:

SEARCH: "{query}"  ·  N results  ·  FTS5 + semantic
══════════════════════════════════════════════════════════════
  #  Name                Type      Confidence  Projects     Updated
 ─────────────────────────────────────────────────────────────────
  1  {title}             {type}    {conf}%     {projects}   {time}
  2  ...

Run /brain-wiki {name} to read the full article.

If 0 results:

No articles found for "{query}".
Entity may not be in any brain DB yet, or articles haven't been generated.
Run: /brain-wiki generate  to generate articles for all brain entities.

`/brain-wiki generate [project]` — Generate / refresh articles

Generates or refreshes knowledge articles from brain DB evidence.

**Procedure:**

1. If a project is specified, confirm scope:

   Generate articles for project "{project}"?
   This will use Claude API (estimated $0.XX for N entities).
   [Y/n]

If no project specified, confirm all:

   Generate articles for ALL registered projects?
   Registered: {slug1}, {slug2}, ...  (N projects, ~N entities)
   Estimated cost: $0.XX  ·  Estimated time: N minutes
   [Y/n]

2. On confirmation, run:

   # Single project
   python3 ~/.coco/knowledge/cron.py --run --project {slug} --phases 2,3,5

   # All projects
   python3 ~/.coco/knowledge/cron.py --run --phases 2,3,5

3. Show phase-by-phase progress as output streams:

   Phase 2: Harvesting evidence...
     ✓ {project}: N entities, N evidence chunks

   Phase 3: Generating articles...
     ✓ Generated: Alice Example (confidence: 87%)
     ✓ Generated: VendorPortal (confidence: 91%)
     ~ Skipped:   3 entities (unchanged)

   Phase 5: Indexing...
     ✓ N articles indexed (FTS5)

   ─────────────────────────────────────────
   KNOWLEDGE ENGINE
   ================
   Articles generated:  N new, N updated
   FTS5 indexed:        N
   Estimated cost:      $0.XXX

   Articles written to: ~/.coco/knowledge/articles/
   Search with: /brain-wiki search "{project}"

4. Add `--force` flag to regenerate all articles regardless of staleness.

`/brain-wiki people` — Show cross-project people graph

Show all person-type articles and cross-project relationship statistics.

**Procedure:**

1. Query knowledge.db directly (do NOT invoke cron --dry-run, per review finding m4):

   import sys, sqlite3, json
   sys.path.insert(0, str(Path("~/.coco/knowledge").expanduser()))
   from schema import KNOWLEDGE_DB_PATH
   conn = sqlite3.connect(KNOWLEDGE_DB_PATH)

   # People articles
   people = conn.execute("""
       SELECT ge.canonical_name, ge.aliases_json, ge.merged_from_json,
              a.confidence, a.generated_at, a.version
       FROM global_entities ge
       LEFT JOIN articles a ON a.gid = ge.gid
       WHERE ge.type = 'person'
       ORDER BY a.confidence DESC NULLS LAST
   """).fetchall()

   # Pending merges
   merges = conn.execute("""
       SELECT COUNT(*) FROM cross_project_connections
       WHERE connection_type = 'proposed_merge'
   """).fetchone()[0]

   # Works-with edges
   edges = conn.execute("""
       SELECT COUNT(*) FROM cross_project_
