Creates and audits the instruction files agents read: agent rules (rules/*.md), the root AGENTS.md with its thin CLAUDE.md bridge, and event-driven hooks (.apm/hooks/hooks.json plus handler scripts). Use when the user wants to write, check, trim or migrate a rule, AGENTS.md or CLAUDE.md, or to add or lint a lifecycle hook such as PreToolUse or SessionStart. Not for skills (use authoring-skills), whole plugins (use authoring-plugins) or GitHub workflows (use authoring-github-workflows).
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
# Authoring Instructions (`authoring-instructions`) Writes lean, invariant-driven instruction files and audits them deterministically: rules, root `AGENTS.md` / `CLAUDE.md`, and plugin hooks. ## Contents - [Constraints](#constraints) • [Modes](#modes) • [Quick start](#quick-start) • [Workflow](#workflow) • [Verification](#verification) • [References](#references) ## Constraints 1. **Rules are constraints, skills are procedures.** A rule states MUST / NEVER / ALWAYS bounds in 30–70 lines (ceiling 80); anything with ordered steps becomes a skill. 2. **Timeless and portable**: no calendar dates, commit SHAs, usernames or absolute machine paths in a rule or root file. 3. **Never overwrite** an existing `AGENTS.md` or `CLAUDE.md`; propose a diff. `CLAUDE.md` stays a bridge of 5 lines or fewer. 4. **Audits are read-only.** They report findings; changes are reviewed edits. …

How to install
mdr add richfrem/agent-plugins-skills/authoring-instructions@sha256:c10921df50facce9The line at the top of this page pins the label git:20261027.494b440, 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.
