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

# AGENTS.md — code-hygiene contributor notes

This repo defines generic, checkable hygiene rules in `skills/` and curated cliff notes in `docs/references/` for skills/tools elsewhere (not vendored). A `catalog` skill helps pick what to install.

## Project discovery

Before editing anything:

```bash
ls CONTRIBUTING.md .github/CONTRIBUTING* templates/AGENTS.md docs/references/index.md
./scripts/phases.py --phase 0
```

Obey CONTRIBUTING.md single-source principle (factual-integrity owns R0, changelog-quality owns subject/body, etc).

## Phase workflow — 6 phases, cumulative, nothing unloads

1. **Phase 0 — project discovery:** `skills/project-discovery/SKILL.md` + `docs/references/index.md`
2. **Phase 1 — spec interview:** `skills/socratic-spec/SKILL.md` — divergent, one Q/turn, closes Open Qs → spec.md
3. **Phase 2 — plan iteration:** `skills/plan-iteration-gate/SKILL.md` — convergent 4Q loop:
   - (a) What's wrong? — tight loops, unbounded state, stale handles, injected input, blind suppression, ambiguous ownership, no verification signal
…

How to install

The exact contents, by fingerprint
mdr add rikvanriel/code-hygiene/AGENTS.md@sha256:59b9579b8ff319c0

The line at the top of this page pins the label git:20260927.dfb67f5, 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.
