Generic two-pass "Double-Knuth" review for ANY repo or file set: Pass 1 = correctness/bugs on the change (delegates to /code-review when a git diff exists, agent-based otherwise), Pass 2 = completeness + cross-file/doc consistency — the defect class a diff reviewer structurally cannot see (stale counts/enumerations, docs contradicting changed behavior, dead paths, orphaned files, contract drift). Read-only: returns a ranked BUG/RISK/NIT list with file:line + concrete fixes. Specialized…
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
# Double-Knuth — generic two-pass review The review standard the website suite already uses, generalized. Run it at the END of a work batch, after a multi-file fix wave, or before trusting a new tool — the moments cross-file consistency silently breaks. Read-only: report findings; fix only when asked. ## Pass 1 — correctness (the change itself) - **In a git repo with a diff:** run the host's diff-review command if it has one (Claude Code: `/code-review`, effort `high` after a fix wave or for new analytics, `medium` for routine edits); on hosts without one (e.g. Codex), review the diff yourself in a fresh context with the adversarial BUG/RISK/NIT prompt. Either way it covers correctness bugs + reuse/simplification. - **No repo / no diff:** spawn a read-only agent over the changed files (or, if the host has no sub-agent primitive, review them in a separate fresh session) asking the two killer questions per guard/test/check: *"can this pass while the thing it protects is broken?"* (Rule 9) and *"does anything skip silently?"* (Rule 12) — hunt latent bugs that green tests cannot see. - If the artifact has its own gate (test suite, build, linter), it must be green …

How to install
mdr add karero/croftweaver/double-knuth@sha256:47dfd46d8ba08f86The line at the top of this page pins the label git:20260702.17487d7, 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.
