SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a product requirements document into an actionable engineering plan is slow and error-prone, often producing vague phases that defer all value to the end. This Skill converts a PRD into a sequenced, reviewable implementation plan that another agent can execute without extra context. ## Core Features & Use Cases - PRD Analysis: Extracts user problems, critical workflows, constraints, non-goals, risks, and open questions from the PRD. - Tracer-Bullet Planning: Structures work as vertical slices that validate risky assumptions early and keep the system working after each phase. - Executable Plan Artifact: Writes a structured plan with phase goals, scope, validation steps, dependencies, and open questions to .prd/<prd-slug>/plans/implementation-plan.md. - Use Case: After drafting a PRD for a new feature, run this Skill to produce a multi-phase implementation plan that a coding agent can pick up in a fresh context window and execute phase by phase. ## Quick Start Use the prd-to-plan skill to turn the PRD at .prd/my-feature/prd.md into a phased implementation plan.

FAQPage Schema
How do I turn a PRD into an implementation plan?▼

Provide the PRD path and the Skill extracts the problem, workflows, constraints, and risks, then writes a phased plan to .prd/<prd-slug>/plans/implementation-plan.md. Each phase includes a goal, scope, validation steps, and risks so another agent can execute it directly.

What is a tracer-bullet or vertical slice implementation plan?▼

A vertical slice plan delivers thin end-to-end increments of working functionality instead of large horizontal layers. This validates risky assumptions early, keeps the system working after each phase, and avoids deferring all user-visible value until the end.

Where is the generated implementation plan saved?▼

The plan is written to .prd/<prd-slug>/plans/implementation-plan.md, alongside the source PRD. The plans directory is created automatically if it does not exist, and the PRD slug is inferred from the artifact if not given explicitly.

Can another AI agent execute the generated plan?▼

Yes, the plan is written to be executable in a fresh context window. It includes explicit phase goals, clear sequencing, concrete validation steps, and constraints placed near the relevant work, with no reliance on unstated tribal knowledge.

What are the limitations of PRD-based implementation planning?▼

The plan quality depends on the PRD's completeness; unresolved risks and open questions are carried into the plan's Open Questions section rather than answered. Major ambiguities in requirements still require human clarification before execution.
