feature-dev

Guide a user from an ambiguous feature idea to an explicitly approved, implementation-ready product specification. Use when brainstorming feature scope, comparing product approaches, resolving ambiguity, or preparing a feature for planning without writing implementation details.

Execute an approved implementation plan step by step with verification evidence and atomic commits. Use when the user asks to run a plan.md, execute planned tasks, resume implementation from a plan, verify each task, or create traceable commits without modifying the plan.

Convert an approved feature specification into a concrete, execution-ready plan.md. Use when the user asks to plan implementation, break an approved spec into tasks, map feature work to repository files, define dependencies, or produce verifiable implementation tasks without writing code.
