Plan skill
name description
plan
Draft implementation plans for new features or substantial behavior changes. Use when the user asks to plan, scope, design, spec, break down, or de-risk a feature before coding, including requests for phased rollout, architecture touchpoints, file-level change lists, validation strategy, or open questions.

Plan

Plan before editing. Produce a plan another coding agent can execute without rediscovering the system.

Ground every recommendation in the current codebase, docs, and project rules.
