SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Break PRDs into structured, multi-phase plans by slicing work into vertical phases that can be demonstrated end-to-end and executed.

Core Features & Use Cases

Interactive prompts present options as a numbered list and wait for the user's choice.
Outputs the plan to .specs/plans/<slug>.md with phase-by-phase tasks, durable decisions, and acceptance criteria.
Guides cross-functional planning from PRD to architecture, API, UI, and tests, ensuring traceability and demoability.

Quick Start

Provide a PRD file and an optional slug to generate a plan at .specs/plans/<slug>.md.

What is vertical slice planning for project management?▼

Vertical slice planning is structuring work into phases that can be demonstrated end-to-end. This approach maps tasks across architecture, API, UI, and tests to ensure cross-functional traceability and demoability for product teams.

How do I break a product requirements document into development phases?▼

Breaking a product requirements document into development phases involves transforming it into multi-phase vertical slices. The generated plan document outlines phase-by-phase tasks, durable decisions, and acceptance criteria for guided execution.

Can I generate a plan file from a PRD without additional dependencies?▼

Yes, you can generate a plan file from a PRD without additional dependencies. You provide a PRD file and an optional slug, and the skill outputs the actionable plan document directly to the .specs/plans directory.

What's the best way to sequence tasks and map dependencies from a PRD?▼

The best way to sequence tasks and map dependencies from a PRD is by generating a structured plan that slices work into vertical phases. This maps architecture decisions and task sequencing across multiple phases for clear execution.
