What problem does it solve? Standard code reviews often miss subtle bugs because reviewers give code the benefit of the doubt. This Skill forces a hostile review posture that assumes bugs exist and hunts for them with concrete triggers, catching logic errors, race conditions, and security flaws before they reach production. ## Core Features & Use Cases - Structured Bug Hunt: Works through seven ordered categories — logic errors, edge cases, error handling, state and concurrency, security, data integrity, and resource management. - Severity-Ranked Findings: Outputs each bug with file location, category, severity (CRITICAL to LOW), a concrete trigger scenario, and a minimal fix. - Use Case: Before merging a pull request that touches payment logic, ask for an adversarial review to surface off-by-one errors, swallowed exceptions, and unsanitized inputs with proof-of-concept triggers. ## Quick Start Review the code in this pull request adversarially and report every bug you find with severity and a concrete trigger.
