Write or edit agent instruction files (`AGENTS.md`, `CLAUDE.md`, `GEMINI.md`, Cursor `.mdc` rules, Copilot instructions, and other harness instruction files). Use when creating, drafting, or editing those files, or when the user wants better agent instructions for a repo. Skip writing an agent skill (SKILL.md); use make-skill.

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

# Write great instructions

Operational policy for a coding agent — not a README. Filename and harness vary; the writing does not.

## Principles

- **Always-on budget.** The expensive file loads on every turn in *this* harness. Root `AGENTS.md`: warn above ~150 lines. Codex shares 32 KiB cumulative along root→CWD; nested does not add a second budget. See caps in [`formats.md`](references/formats.md).
- **Signal.** Headings reset attention: one topic each, depth stops at `h3`. A command lives in backticks (in a sentence it is a suggestion). When a heading is earned, use a familiar name (`Commands`, `Testing`, `Boundaries`, `Conventions`, `Structure`). Do not invent a required skeleton.
- **Observable or attachable.** Always-on: a command (prefer the per-file form of lint/test/typecheck in the working loop), an observable condition, a CORRECT/WRONG snippet, or a pointer to a gold file in this repo. Glob: a convention for that slice. Cut no-ops (`write clean code`, `follow best practices`, `handle errors gracefully`).

How to install

The exact contents, by fingerprint
mdr add diegoos/skills/write-great-instructions@sha256:7e325caeb2be7585

The line at the top of this page pins the label v0.5.1, 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.
