| description | Audit and evolve the brain vault — prune outdated content, discover cross-cutting principles, review skills for structural encoding opportunities. Triggers: "meditate", "audit the brain". |
Meditate
Quality bar: A note earns its place by being high-signal (Claude would reliably get this wrong without it), high-frequency (comes up in most sessions or most tasks of a type), or high-impact (getting it wrong causes significant damage or wasted work). Everything else is noise. A lean, precise brain outperforms a comprehensive but bloated one.
Process
1. Build snapshots
sh .claude/skills/meditate/scripts/snapshot.sh brain/ /tmp/brain-snapshot.md
sh .claude/skills/meditate/scripts/snapshot.sh .claude/skills/ /tmp/skills-snapshot.md
Files are delimited with === path/to/file.md === headers. Also locate the auto-memory directory (~/.claude/projects/<project>/memory/).
2. Auditor (blocking — its report feeds step 3)
Spawn general-purpose subagent. See references/agents.md for the full prompt spec. Inputs: brain snapshot, auto-memory path, CLAUDE.md path.
Audits brain notes, CLAUDE.md, and auto-memory for staleness, redundancy, low-value content, verbosity, and orphans. Returns a categorized report.
Early-exit gate: If the auditor finds fewer than 3 actionable items, skip step 3 and go directly to step 4.
3. Reviewer (after auditor completes)
Spawn one general-purpose subagent. See references/agents.md for the full prompt spec. Inputs: brain snapshot, skills snapshot, auditor report, brain/principles.md.
Combines three concerns in a single pass:
- Synthesis: Proposes missing wikilinks, flags principle tensions, suggests clarifications.
- Distillation: Identifies recurring patterns that reveal unstated principles. New principles must be (1) independent, (2) evidenced by 2+ notes, (3) actionable.
- Skill review: Cross-references skills against brain principles. Finds contradictions, missed structural enforcement, redundant instructions.
4. Review reports
Present the user with a consolidated summary. See references/agents.md for the report format.
5. Route skill-specific learnings
Check all reports for findings that belong in skill files, not brain/. Update the skill's SKILL.md or references/ directly. Read the skill first to avoid duplication.
6. Apply changes
Apply all changes directly. The user reviews the diff.
- Outdated notes: Update or delete
- Redundant notes: Merge into the stronger note, delete the weaker
- Low-value notes: Delete
- Verbose notes: Condense in place
- New connections: Add
[[wikilinks]]
- Tensions: Reword to clarify boundaries
- New principles: Only from the distillation section, only if genuinely independent. Write brain files and update
brain/principles.md
- Merge principles: Look for principles that are subsets or specific applications of each other — merge the narrower into the broader
- CLAUDE.md issues: Rewrite or delete
- Stale memories: Delete or rewrite
7. Housekeep
Update brain/index.md for any files added or removed.
