Config

Vault path + GitHub task repo: read from ${CLAUDE_PLUGIN_ROOT}/brain-os.config.md (or user-local ~/.brain-os/brain-os.config.md). Keys: vault_path:, gh_task_repo:. Substitute $GH_TASK_REPO below with the configured value.

Study — Full Knowledge Pipeline Orchestrator

Usage

/study <epub_path> --notebook-id <nlm_id>
/study --resume              Resume a pipeline that was interrupted
/study --status              Show pipeline status for all books

Full Pipeline

Step 1: /self-learn --book <epub> --notebook-id <id>
  ├── Phase 1: Extract (epub → atomic notes in knowledge/raw/)
  ├── Phase 2: Validate (questions vs NotebookLM, ≥95 threshold, 100% pass)
  └── Phase 3: Extend + Ingest (book note in knowledge/books/ + synthesis)
        ↓
Step 2: /verify (50 fresh questions vs NotebookLM → audit flag)
  ├── PASS → audited: true
  └── FAIL → audited: false → STOP, notify user
        ↓
Step 3: /absorb (book note → vault connections, bypass approval since audited: true)
        ↓
Step 4: commit + push (git commit + push all changes)
        ↓
Step 5: Notify all 3 channels
  ├── GH issue at $GH_TASK_REPO (review task)
  ├── Daily note entry
  └── Audit flag updated with pipeline_completed timestamp

How to Execute

IMPORTANT: Run each step sequentially. Do NOT skip steps.

Step 1: Self-Learn (includes ingestion)

/self-learn --book <epub_path> --notebook-id <nlm_id>

Wait for all 3 phases to complete. Phase 3 now creates the structured book note in knowledge/books/ (previously a separate /ingest step). Check with /self-learn --status.

Step 2: Verify

PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT:-$(ls -d ~/.claude/plugins/cache/brain-os-marketplace/brain-os/*/ 2>/dev/null | sort -V | tail -1)}"; PLUGIN_ROOT="${PLUGIN_ROOT%/}"
python3 ${PLUGIN_ROOT}/skills/verify/scripts/verify.py {vault}/knowledge/raw --status

If flag is false, run /verify with 50 fresh questions. If flag is already true (from self-learn validation), proceed.

Step 3: Absorb

Run the /absorb skill. Since verify is true, bypass approval — apply all vault connections automatically.

Step 4: Commit + Push

Commit and push all vault changes to git.

Step 5: Notify

• Create a review task as a GH issue via the central filer (validates every label axis against canon — see references/gh-task-labels.md):

  bash "$CLAUDE_PLUGIN_ROOT/scripts/gh-tasks/create-task-issue.sh" \
    --title "Review $BOOK_TITLE notes" \
    --body "..." \
    --area vault \
    --owner human \
    --priority p3 \
    --weight quick \
    --status ready
  

  area:vault because the review operates on absorbed vault knowledge; priority:p3 per the filer matrix default for review tasks (not p4 — that label is retired)
• Create/update daily note with pipeline log
• Update audit flag with pipeline_completed timestamp

Pipeline State

Each book's pipeline state is tracked in _validation/audit-flag.json:

{
  "flag": "true|false|manual",
  "last_audit": "ISO timestamp",
  "audit_score": "159/159 at >=95",
  "pipeline_completed": "ISO timestamp",
  "ingested": true,
  "absorbed": true
}

Resume

If pipeline is interrupted, /study --resume checks audit-flag.json to determine which step to resume from.

Error Handling

• Phase 2 fails (< 100% pass): Loop continues fixing until 100%. No timeout.
• Verify fails: Pipeline stops. Flag stays false. Task written to inbox.
• Git push fails: Pull first, resolve conflicts, retry push.
• NotebookLM timeout: Retry 3 times with backoff. If still failing, pause and notify user.

Outcome log

Follow skill-spec.md § 11. Append to {vault}/daily/skill-outcomes/study.log:

{date} | study | study | ~/work/brain-os-plugin | knowledge/books/{slug}.md | commit:{hash} | {result}

• result: pass if full pipeline complete (self-learn → verify → absorb → commit), partial if interrupted mid-pipeline, fail if verify fails
• Optional: args="{epub_path}", score={step_reached}/5
