What this skill does

Review code for actionable defects. Correctness is the core; performance and security are optional sub-cases of the same engine. Anchors on agreements between participants across a boundary, forces a violating execution, and refutes every candidate before reporting. Use when asked to review changes, find bugs, audit a codebase, or check whether a fix is safe. Most review output is noise: a list of things that look wrong, unranked, unrefuted, and impossible to act on.

When it triggers

  • Use when asked to review changes, find bugs, audit a codebase, or check whether a fix is safe.
