context-audit SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
context-audit from garrytan/gbrain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add garrytan/gbrain/context-audit@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Token-hygiene audit of the always-loaded context stack — CLAUDE.md, AGENTS.md, auto-memory MEMORY.md, and the bootstrap-rendered identity files (SOUL.md, USER.md, ACCESS_POLICY.md, HEARTBEAT.md) or their harness equivalents. Finds redundancy, contradictions, stale content, compression candidates, and skill-extraction candidates; produces a ranked action list sorted by token savings with a risk class per finding. REPORT-ONLY: this skill never edits any audited file. Recommendations for…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# context-audit — Token Hygiene for the Always-Loaded Context Stack > **Convention:** see [conventions/brain-first.md](../conventions/brain-first.md) > — before running a fresh audit, check the brain for prior audit reports > (`gbrain recall "context audit report"`) so you can compute token DRIFT since > the last run and avoid re-flagging findings the user already declined. > > **Convention:** see [conventions/quality.md](../conventions/quality.md) — > every finding cites its file and evidence; no unsourced claims. ## What this is Every file that loads on every turn is a per-turn tax: tokens, latency, and — past a point — instruction-following quality. Always-loaded files accrete (append-only release notes, promoted memory blocks nobody re-reads, rules restated in three files that drift into contradiction). This skill audits the whole always-loaded stack at once and returns a ranked, evidence-cited action list sorted by token savings. It is an auditor, not a surgeon. It measures, finds, ranks, and recommends. The user (or a skill the user explicitly invokes afterward) applies changes. ## Scope: what counts as "always-loaded" …

How to install
mdr add garrytan/gbrain/context-audit@sha256:1eeb9057d25ea376The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
