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
# Project conventions for Claude This file captures project-specific conventions Claude should follow when working in this repo. ## Repository tooling - `bin/validate-patterns` validates every detection pattern YAML file under `rails-upgrade/detection-scripts/patterns/`. Run it before committing any change to a pattern file. Pure-stdlib Ruby, no Bundler or Gemfile required. - `bin/validate-patterns` validates every file - `bin/validate-patterns path/to/file.yml` validates one or more specific files - `bin/validate-patterns --self-test` runs built-in fixture assertions covering the four positive `kind:` values and the rejection paths (missing top-level key, missing required pattern key, broken regex, broken, control-character or look-around `unless_file_matches`, unknown `kind:` value, a control character from a single-backslash YAML escape, catastrophic backtracking). CI runs this alongside the file-validation step …

How to install
mdr add ombulabs/claude-code_rails-upgrade-skill/CLAUDE.md@sha256:a949eed56716b4c7The line at the top of this page pins the label git:20261104.631e5b8, 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.
