Plans a user-provided feature idea by reading SPEC and code (read-only), analyzing scope, proposing a design aligned with existing architecture, optionally clarifying underspecified requirements with focused questions, and opening a GitHub issue that documents requirements, assumptions, design, subtasks with dependencies, and acceptance criteria—without modifying the repository. Use when the user wants a feature scoped and filed as an issue before any implementation, spec edits, or PR work.
