Proves code is unreachable with converging evidence, then removes it and its tests, fixtures, and flags in reversible slices without breaking dynamic callers. Use when deleting suspected dead code, cleaning up after a migration or feature retirement, trimming a bloated module, or before estimating work on unfamiliar code. Do NOT use when you want to survey and rank an area's debt without committing to deletion - use find-tech-debt instead.
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 Eliminator Delete code only after converging evidence proves it dead, then remove it in reversible slices that include its tests, fixtures, config, and flags. ## Workflow 1. **Scope one cluster.** Pick a single symbol, file, or feature to prove dead. Do not batch unrelated removals - a regression must point to one change. 2. **Gather static evidence.** Run the language's dead-code detector (ts-prune or knip for TS/JS, vulture for Python, `deadcode` for Go) and a dependency grapher (madge) or IDE "find usages". Record what each reports unreachable. 3. **Gather runtime evidence.** Check production coverage or profiling data over a representative window - at least 30 days for user-facing paths, 90+ days for code tied to monthly or quarterly jobs - and telemetry: was this endpoint, job, or branch hit this quarter? A symbol is a deletion candidate only when static analysis AND runtime evidence agree. One signal alone produces false positives that take down prod. …

How to install
mdr add skillmedev/skills/dead-code-eliminator@sha256:960a4568cb4bf1f3The line at the top of this page pins the label git:20261005.bea4ea5, 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.
