Use when asked to find bugs, hunt for correctness issues, sweep a codebase for defects, or verify a repo behaves as intended. Not for style or architecture review; this is defect-finding only.
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-hunt A correctness sweep that only reports bugs it failed to refute. Finders generate candidates; verifiers try to kill them; survivors make the report. The single biggest failure mode of agent bug-hunting is plausible-but-wrong findings, so verification is not optional. **Read-only.** Finding bugs and fixing them are separate engagements. ## Lenses Sweep with each lens. With parallel subagents available, one finder per lens; otherwise sequential passes. | Lens | Hunting for | |------|-------------| | Logic | Inverted conditions, off-by-one, wrong operator, unreachable branches, broken invariants | | Error handling | Swallowed exceptions, missing error paths, errors that corrupt state before propagating, misleading messages | | Edge cases | Empty/nil/zero inputs, unicode, huge inputs, boundary values, first/last iteration | | Concurrency | Races, missing locks, shared mutable state, TOCTOU, async ordering assumptions | | API misuse | Contract violations against libraries and the project's own interfaces, ignored return values, resource leaks, lifecycle errors | …

How to install
mdr add escoffier-labs/brigade/bug-hunt@sha256:c023e8d6fb93e307The line at the top of this page pins the label git:20260712.7784bda, 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.
