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

# Development skills

This repository is the source of the `development-skills` plugin for Claude Code and Codex CLI.

1. Challenge unsupported assumptions. Evidence validates a decision; agreement alone does not.
2. Use the smallest useful change. Every changed line must trace to the request.
3. Follow [`shared/development-loop.md`](shared/development-loop.md) for scope, authorization, checks, and completion.
4. Follow [`shared/writing.md`](shared/writing.md) for every natural-language artifact.
5. Follow [`shared/engineering.md`](shared/engineering.md) for code and design.
6. Test new behavior with a failing proof when practical. Keep refactor characterization proof green before and after.
7. Never suppress a failing check or weaken proof to claim success.
8. Preserve user work and inspect callers before removing or moving files.
9. Store durable reasons in chronicles and resumable execution state in plans.
10. Commit only when explicitly requested or authorized by an explicitly invoked skill. Never add AI attribution or `Co-Authored-By` trailers.

- Skills and agents reference canonical files under `shared/`; they do not copy those contracts.

How to install

The exact contents, by fingerprint
mdr add reidemeister94/development-skills/AGENTS.md@sha256:ea2b2d7c03e19320

The line at the top of this page pins the label git:20261031.a82a617, 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.
