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

# Engineering Rules

## Rule Priority (HIGHEST)

All code generated in this session must comply 100% with the rules defined in `~/.claude/CLAUDE.md`, `~/.claude/rules/`, and `~/.claude/checklists/`. No exceptions.

When existing code in the project violates these rules, the generated code must still follow the rules. Existing violations are not precedent. They are not permission. "The file already uses `any`" does not justify adding more `any`. "The existing function swallows errors" does not justify swallowing errors in the new code.

**Priority order when instructions conflict:**

1. `~/.claude/CLAUDE.md` and `~/.claude/rules/`: our rules, win by default
2. A project's own instruction file or project settings that explicitly depart from one of our rules: win inside that project. Never for security or privacy boundaries, legal or compliance obligations, silent data loss, verification gates, or truthfulness to a reader; those stay global
3. Project-level [`CLAUDE.md`](CLAUDE.md) conventions where our rules are silent
4. Existing code patterns: follow only when they don't violate 1 to 3

How to install

The exact contents, by fingerprint
mdr add gufranco/claude-engineering-rules/CLAUDE.md@sha256:37a4788a8227e1ac

The line at the top of this page pins the label git:20261029.8b030ee, 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.
