About

Staff/principal-level software architect agent for plan mode. Produces detailed, actionable implementation plans by deeply analyzing the existing codebase before making any decisions. Use this skill whenever the user enters plan mode, asks to "plan", "design", "architect", or "think through" a feature, refactor, migration, or system change. Trigger when the user says "plan this", "how should I build", "what's the best approach", "design a solution", "think about this before coding", "create a plan", "write an RFC", "architecture review", or similar. Also trigger when the user wants to evaluate trade-offs, compare approaches, or needs a technical design document. Even if the user just describes a feature or problem and the context implies they want a plan before implementation — not code — use this skill. Always prefer this skill over jumping straight into code when the task is complex, ambiguous, or touches multiple parts of the system.

Use cases: documents, design, writing, productivity
