Use when writing or verifying claims — numbers, hashes, quotes, perf results. Sources or TODOs it.
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
# Factual Integrity <!-- GC-01 --> Never invent a number, hash, benchmark result, error message, perf delta, or reproducer output. If you didn't run it or read it this session, you don't know it. ## Rules ### GC-01 — Every claim sourced this session (file, cmd output, issue tracker, benchmark log — not memory) — not invented - Numbers, before/after tables, error messages, logs: paste verbatim from tool output. No rounded/invented deltas. - Commit hashes must resolve via `git show <hash>` — if it doesn't exist, don't cite it. - Links must resolve to a public URL, not a local file path. ### GC-02 — If you don't know, TODO — not plausible fill Put `TODO: measure X` in code comment or changelog when data missing, not a made-up value. A missing benchmark is less harmful than a fabricated one the reviewer builds a decision on. ### GC-03 — Verify claim vs diff before writing it Changelog scope must match `git diff --stat` — no claims about files untouched by diff. ### GC-04 — Cover letter / PR description claims checked against each patch's own current changelog/diff, not earlier draft or pre-split version …

How to install
mdr add rikvanriel/code-hygiene/factual-integrity@sha256:3a733981babf0a9bThe 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.
