Turn a PRD into an Implementation Plan

This skill translates what needs to be built (the PRD) into how it will be built (a phased implementation plan). It breaks the PRD into tracer-bullet vertical slices, orders them into phases, and writes the result as a Markdown plan file in ./plans/.

When to Use

Use this skill when:

  • You already have a PRD or equivalent spec and now need a concrete implementation plan.
  • You want to think in phases, not just issues: what gets built first, what can be deferred, and how slices build on each other.
  • You intend to drive downstream work (e.g. /slice-the-spec, /incremental-tdd) from a single, durable planning document.

If the requirements are still fuzzy, use /grill-me and /spec-writer first.

Workflow

You can compress steps if the context is already clear, but keep the core structure: PRD → slices → phases → plan file.
