Only for explicit prior-work/reuse/history requests, not status checks. Finds and verifies existing work before new production when reuse is plausible. Use when the user explicitly references earlier work, existing code, history, or prior decisions, or says 以前做过, 已有代码, 别重复造轮子. Not for current tests, files, bug fixes, or mechanical verification. Produces a reuse/adapt/reject receipt; zero hits never prove absence.
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
# Prior Work Retrieval Run this before substantial production **only when the trigger above is present**. Read-only current-state checks stay direct unless the user asks for history. Its job is not to generate another summary. Its job is to answer: **what already exists, which source is current, what should be reused, and what remains genuinely new?** **Not for**: current-file inspection, ordinary bug fixes, mechanical verification, or a task merely because the final answer happens to be a report/summary. A mention of current/现有 tests, README, files, implementation, behavior, or validation is not by itself a prior-work request. Do not infer the trigger merely because new work might duplicate something — that risk alone does not make a request explicit. ## Completion contract A retrieval pass is complete only when all conditions below are true: 1. The task's real business outcome is written as one sentence. 2. Every relevant carrier declared in the manifest reports `searched`, `manual_completed`, or an explicit failure/coverage gap. 3. Candidate claims are opened at their original path or record, not accepted from a search snippet alone. …

How to install
mdr add daymade/claude-code-skills/prior-work-retrieval@sha256:35bb0934edf9b2afThe line at the top of this page pins the label git:20261105.7a6b743, 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.
