About This Skill
What it does
The Product Spec Kit skill assists Product Managers in generating structured, high-quality documentation for product development. It supports both comprehensive workflows (Product Requirements Document [PRD] → Plan → User Stories) and standalone document creation like individual stories or bug reports. The tool ensures consistency by adhering to a defined constitution and mirroring the user’s language in generated documents.
When to use it
- Creating a Product Requirements Document (PRD).
- Generating an epic and associated user stories/tasks.
- Clarifying existing product specifications like PRDs, Release Plans, User Stories, Tasks or Bugs.
- Producing standalone documentation for individual items such as a PRD, Plan, Story, Task, or Bug.
Key capabilities
- Generates Product Requirements Documents (PRDs).
- Creates epics and associated user stories/tasks.
- Supports clarification of existing product specifications.
- Adheres to a defined constitution for consistent documentation principles.
- Uses the language specified by the user in generated documents.
Example prompts
- "Create a PRD for our new mobile app feature."
- "Can you help me break down this PRD into smaller stories and tasks?"
- “I need to clarify some acceptance criteria for an existing User Story.”
Tips & gotchas
- The skill operates according to a constitution (rules/product-speckit-constitution.md) that dictates principles like clear requirements, design-driven acceptance criteria, and functional descriptions over visual details. These principles are non-negotiable.
- If you don't specify the type of specification you want to create initially, the skill will ask for clarification.
- To break down a PRD into smaller parts (Epics/Stories), you must first either validate an existing PRD or create one.
