An Agent Skill that uses your most capable model to audit a codebase, judge what is worth doing, and write self-contained implementation plans for cheaper models to execute. It never implements anything itself; the output is plain markdown plans in plans/, with modes for full, quick, deep, security, branch-scoped audits and optional GitHub issue publishing.
What this means for indie developers：Indie developers can split AI-assisted code auditing and fixes into expensive-model planning plus cheap-model execution, keeping maintenance costs low.
