What problem does it solve? Starting a new feature without a clear plan leads to scope creep, missed edge cases, and inconsistent code. This Skill turns a short feature description into a structured, task-by-task implementation plan grounded in your project's architecture, conventions, and roadmap. ## Core Features & Use Cases - Two planning modes: Fast mode produces a quick single-file plan, while Full mode asks about tests, logging, and docs preferences, then writes a richer plan with phases, dependencies, and commit checkpoints. - Git-aware workflow: Optionally creates a feature branch or a parallel git worktree, with sequential plan numbering and worktree list/cleanup subcommands. - Project context integration: Reads project description, architecture, roadmap, and research artifacts so tasks follow existing conventions and can link to roadmap milestones. - Use Case: Run the full mode with a description like "Add user authentication with OAuth" to get a phased plan with test and logging requirements saved under your plans directory, ready for implementation. ## Quick Start Ask the assistant to plan a new feature in full mode, for example: plan the implementation of user authentication with OAuth.
