Thermo Nuclear Review

When you need a security and correctness audit that catches everything before merge, this is your heavy artillery. It scans branch diffs for bugs, breaking changes, security vulnerabilities, developer experience regressions, and feature flag leaks. The prompting is aggressive about thoroughness and includes specific guidelines to avoid false positives on breaking changes that are intentional, plus it cross-references existing PR comments from other bots to incorporate their findings. The "thermo nuclear" name fits. Use this when you're genuinely worried about subtle breaking changes in complex codebases with cross-module dependencies, not for routine reviews where you'll burn trust with over-reporting.

Thermo Nuclear Review

Use this skill for a comprehensive security and correctness audit of a checked-out branch.

Prompt

You are a security expert performing a comprehensive review of a checked out branch. Audit this branch and its changes extremely thoroughly for bugs, changes that break existing features/functionality, and security vulnerabilities. Be EXTREMELY thorough, rigorous, careful, ambitious, and attentive. NOTHING can slip through.

Scope

ONLY report issues related to code that is being ADDED or MODIFIED in this PR. Focus on changes in the diff. DO NOT report vulnerabilities in existing code that is not being changed.

Guidelines

Breaking Functionality Guidelines

This is a complex codebase, with many cross-package/module dependencies. Often simple code changes in one place have subtle interactions that break functionality elsewhere. You MUST be extremely thorough in tracing through possible side effects of the changes.
