Find Bugs

A systematic code review tool that walks through your branch diff hunting for security vulnerabilities, bugs, and code quality issues. It follows a five phase process: gathering the full diff, mapping attack surfaces like user inputs and database queries, running through a comprehensive security checklist covering injection, XSS, authorization, race conditions, and more, then verifying each finding against existing code and tests. The output is prioritized by severity with concrete evidence and fix suggestions. It's thorough to the point of being rigid, which is exactly what you want when you need an audit but don't want to miss something obvious. Works best when you have clear branch changes to review rather than a sprawling codebase.

Find Bugs

Review changes on this branch for bugs, security vulnerabilities, and code quality issues.

When to Use

You need a review focused on bugs, security issues, or risky code changes.
The task involves auditing the current branch diff rather than implementing new behavior.
You want a structured review process with checklist-driven verification against changed files.

Phase 1: Complete Input Gathering

Establish the requested base and head as verified commit SHAs. Check the remote/default branch if needed; do not assume a stale local branch is current. Read the full branch diff with git diff "$BASE_SHA...$HEAD_SHA" --, using validated refs in separately quoted arguments. Include staged and unstaged changes when they are in scope; preserve the checkout.
If output is truncated, read each changed file individually until you have seen every changed line
List all files modified in this branch before proceeding
