Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Use to turn an approved spec into an implementation plan.Key capabilities
- →Read the constitution, plan template, and feature `spec.md`
- →Write a Constitution Check covering every principle
- →Show only affected paths in Project Structure
- →Define technical direction, risks, and validation
- →Write to `.specify/specs/NNN-feature/plan.md`
How it works
The skill processes an approved feature specification, performs a constitution check, outlines project structure changes, and defines technical aspects for an implementation plan.
Inputs & outputs
When to use speckit-plan
- →Create implementation plan from spec
- →Perform constitution check
- →Define project structure changes
About this skill
speckit-plan Skill
Use to turn an approved spec into an implementation plan.
Rules
- Read the constitution, plan template, and feature
spec.md. - Write a Constitution Check covering every principle.
- Show only affected paths in Project Structure.
- Define technical direction, risks, and validation.
- Write to
.specify/specs/NNN-feature/plan.md.
When not to use it
- →When a spec has not been approved
- →When the task is not to create an implementation plan
Limitations
- →Requires an approved spec as input.
- →Output is limited to `.specify/specs/NNN-feature/plan.md` format.
How it compares
This skill provides a structured, rule-based approach to converting a spec into an implementation plan, ensuring all constitutional principles are checked and specific output formats are followed, unlike a manual planning process.
