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
# Rails Expert ## Core Workflow 1. **Analyze requirements** — Identify models, routes, real-time needs, background jobs 2. **Scaffold resources** — `rails generate model User name:string email:string`, `rails generate controller Users` 3. **Run migrations** — `rails db:migrate` and verify schema with `rails db:schema:dump` - If migration fails: inspect `db/schema.rb` for conflicts, rollback with `rails db:rollback`, fix and retry 4. **Implement** — Write controllers, models, add Hotwire (see Reference Guide below) 5. **Validate** — `bundle exec rspec` must pass; `bundle exec rubocop` for style - If specs fail: check error output, fix failing examples, re-run with `--format documentation` for detail - If N+1 queries surface during review: add `includes`/`eager_load` (see Common Patterns) and re-run specs 6. **Optimize** — Audit for N+1 queries, add missing indexes, add caching ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Hotwire/Turbo | `references/hotwire-turbo.md` | Turbo Frames, Streams, Stimulus controllers | …

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.
