Restructure an always-loaded rules file such as CLAUDE.md or MEMORY.md: build a top block of key rules plus numbered categories, move rule bodies verbatim with a script that proves zero byte loss, fold heavy mechanics into trigger-plus-pointer form, then guards, a canary window and fleet rollout. For scheduled maintenance, not ad-hoc trimming. Triggers: "/canon-revision", "revise the canon".
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
# canon-revision — revising an always-loaded rules file The pain: the rules file grows through intake, the structure drifts, and the important parts drown in the middle. The owner's decision (2026-07-22): live in cycles — free growth up to the yellow zone, then a FULL structural revision. This procedure is that revision, battle-tested on CLAUDE.md v2. Roles: the LLM decides ONLY (a) the mapping of sections into categories, (b) the contents of the TOP block, (c) which sections to fold, plus pinpoint edits from the owner's explicit decisions. The bytes are moved by the SCRIPT, which proves by itself that nothing was lost. Never retype the file by hand. ## Step 0 — RECALL + the frame - Memory: [[claude-md-compression-contract]] (the contract: trigger · directive · clauses · pointer; the two-ends pitfall), [[write-service-files-tight-no-recompress]], [[memory-index-hygiene]] (for MEMORY.md), [[declined-decisions]] (word-level re-compression = declined). - Thresholds = the defaults in `~/.claude/scripts/claude_md_guard.py` (owner, 07-22: yellow 100KB · red 120KB). The truth is the guard's code, not the notes. - A revision = a canon edit → the owner's machine only, in a live session. …

How to install
mdr add tonydzi/second-brain-starter-kit/canon-revision@sha256:82e2fa39dfa4b3c6The line at the top of this page pins the label git:20261020.402f6b7, 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.
