What problem does it solve? Reviewing branch changes for bugs and security flaws is error-prone when done ad hoc, and reviewers often miss injection, authorization, or race condition issues hidden in large diffs. ## Core Features & Use Cases - Full Diff Analysis: Gathers the complete branch diff against the default branch and maps the attack surface of every changed file. - Security Checklist: Systematically checks injection, XSS, authentication, authorization/IDOR, CSRF, race conditions, session handling, cryptography, information disclosure, DoS, and business logic flaws. - Verified Findings: Confirms each issue is real before reporting, then outputs prioritized findings with severity, evidence, and concrete fixes. - Use Case: Before merging a pull request, run this Skill to audit all changes on the branch and receive a severity-ranked report of vulnerabilities and bugs without modifying any code. ## Quick Start Review the changes on this branch for bugs, security vulnerabilities, and code quality issues.
