Audit and evolve the brain vault — prune outdated content, discover cross-cutting principles, review skills for structural encoding opportunities. Triggers: "meditate", "audit the brain", "prune brain", "review skills", "consolidate notes", "prune notes".
When running non-interactively (Cook, Oops, Repair):
/commit skill.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.
Use Tasks to track progress (TaskCreate per step, TaskUpdate to in_progress/completed).

sh <skill-path>/scripts/snapshot.sh .agents/skills/ /tmp/skills-snapshot.md
Files are delimited with === path/to/file.md === headers. Also locate the auto-memory directory (~/.claude/projects/<project>/memory/).
Spawn general-purpose subagent. See references/agents.md § Auditor 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.
Spawn one general-purpose subagent. See references/agents.md § Reviewer for the full prompt spec. Inputs: brain snapshot, skills snapshot, auditor report, brain/principles.md.
Combines three concerns in a single pass:
Present the user with a consolidated summary. See references/agents.md § Report Template for the format.
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.
Apply all changes directly. The user reviews the diff.
[[wikilinks]]brain/principles.mdClean stale .noodle/ state (old debates, completed sessions, stale plan artifacts). Update brain/index.md for any files added or removed.
## Meditate Summary
- Pruned: [N notes deleted, M condensed, K merged]
- Extracted: [N new principles, with one-line + evidence count each]
- Skill review: [N findings, M applied]
- Housekeep: [state files cleaned]
