What problem does it solve?
Finds real bugs in code — defects you can prove with a specific input, state, or interleaving that produces observable harm. Bugs only. Style, naming, docs, and refactoring belong in code-scrutiny and refactor-pro. (ultrathink)
The methodology is grounded in empirical bug-finding research, cited inline where it earns a specific decision — not as a reading list.
The skill guides users through a rigorous, lens-based bug-hunting process that prioritizes verifiable impact over superficial code quality improvements.
Core Features & Use Cases
- Rotating lenses (null/boundary, error-path, concurrency, taint, inconsistency, invariants) surface real bugs with concrete witnesses.
- Witness-based bug reports include a specific input/state sequence, observable harm, and a clear reachability path.
- Structured reports enable triage, replication, and remediation across single-file to large repos.
