Hunt for one real, previously unreported defect and file it as a well-evidenced ticket — proactive discovery, not reactive diagnosis. INVOKE when asked to sweep code for bugs or hunt risky areas, and when /sonu:factory runs a bug-hunt pass. A known symptom is [[debugging]]; a pending diff is [[self-review]]. It files one ticket; it never fixes, changes code, or opens a PR.
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
# Bug finder — find one real defect, prove it, file it Most bugs reach production because nobody was looking in the places bugs live. This pass goes looking deliberately, and it holds itself to a standard that makes the output worth a human's attention: **one concrete defect, backed by evidence, filed as a ticket somebody can act on.** The failure mode this skill is built to prevent is the plausible-sounding audit — twenty speculative observations, no reproduction, no evidence. That output is worse than silence: every item costs a maintainer time to dismiss, and after one such report the next one gets ignored entirely. One proven bug beats twenty maybes, so the bar is deliberately set where speculation cannot clear it. ## How to apply this Apply to `$ARGUMENTS` — the text typed after the invocation, an optional area to hunt in (a directory, module, or subsystem). If that token appears literally or is empty, choose the hunting ground yourself using section 1's priorities. Load `Skill(sonu:ticket-lifecycle)` for the tracker and the create operation, then run sections 1 through 4 in order. Sections 2 and 3 are the gate: **nothing gets filed that has not cleared them.** --- …

How to install
mdr add prabhdeepsingh/claude-plugins/bug-finder@sha256:7bd7bf510144c2f0The line at the top of this page pins the label git:20260825.06c64c5, 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.
