Planner

The planner skill breaks down implementation requests into detailed, phased plans with sprints and atomic tasks by first researching the codebase and clarifying requirements with the user, then retrieving relevant documentation and generating structured, actionable steps. It's designed for developers who need to organize complex features, bugs, or tasks into manageable, demoable increments with clear dependencies and validation methods. The skill solves the problem of vague or overwhelming project scope by forcing specificity at the task level and ensuring each sprint delivers testable, runnable progress.
