Find code that can never run and delete it without breaking a caller you missed. Use when pruning unused functions, branches, feature flags, or files.
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
# Dead code removal Unused code is not free: it is read during every search, dragged along in every refactor, and trusted during every audit, all for logic that never executes. The risk is deleting something that only looks dead, so removal is a verification job before it is a deletion job. ## Method 1. **Confirm no reference before touching a symbol.** Grep the whole tree, not just the current package: `grep -rn "functionName" .`. Include tests, config, string-based lookups, and reflection or dependency-injection names that a symbol search misses. Zero hits across all of these is the bar. 2. **Read a coverage report to find never-run lines.** Run the suite under coverage (`coverage.py`, `c8`, `go test -cover`) and look for functions and branches sitting at 0 percent. Coverage flags candidates; it does not prove death, since untested is not the same as unreachable. Pair it with grep. 3. **Check exported and dynamic surfaces harder.** A public export, a route handler, a serialized class name, or a plugin entry can be called by code you do not own. For these, search callers outside the repo, or deprecate for one …

How to install
mdr add amey-thakur/ai-skills/dead-code-removal@sha256:764f430ee3ab9321The line at the top of this page pins the label git:20260718.7c1285c, 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.
