💡 Summary
An AI skill that conducts structured code reviews, providing actionable feedback on quality, security, and maintainability.
🎯 Target Audience
🤖 AI Roast: “It's like having a senior engineer on call, assuming your senior engineer only reads the files you give them and can't run the code.”
Skill uses Read/Grep/Glob tools to access filesystem. Primary risk is path traversal via user input leading to unauthorized file reads. Mitigation: Agent platform must strictly sandbox and validate all file paths before passing to tools.
