SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams transform feature requirements into structured implementation plans by coordinating research, design artifacts, validation checks, and project context updates.

Core Features & Use Cases

  • Planning Workflow Execution: Runs a spec-driven planning process that creates research notes, data models, contracts, quickstart documentation, and implementation plan artifacts.
  • Project Context Integration: Checks SpecKit project structures, extension hooks, constitution rules, and agent context updates before and after planning.
  • Use Case: Use this Skill when starting a new software feature and needing a complete technical plan aligned with existing repository conventions.

Quick Start

Use the speckit-plan skill to create an implementation plan for the requested feature while following the repository SpecKit workflow.

FAQPage Schema
How do I create an implementation plan from feature specifications?

To create an implementation plan from feature specifications, use a spec-driven planning process that generates research notes, data models, contracts, and quickstart documentation. This coordinates design artifacts and validation checks to produce aligned engineering outputs.

What is a spec-driven planning workflow in software engineering?

A spec-driven planning workflow in software engineering transforms feature requirements into structured technical plans. It coordinates research generation, data modeling, and context updates to ensure implementation aligns with existing repository conventions before development begins.

Do I need a SpecKit directory structure to generate feature design artifacts?

Yes, generating feature design artifacts requires a SpecKit directory structure. The planning process checks project structures, extension hooks, and constitution rules to validate context and produce aligned implementation plans.

How do I integrate project context and validation gates into feature planning?

You integrate project context and validation gates by running planning workflows that check repository conventions, update agent context, and apply validation scripts. This ensures feature design artifacts align with existing project structures before and after planning.

What's the best way to turn feature ideas into technical plans for a new software feature?

The best way to turn feature ideas into technical plans is using a structured spec-driven workflow. It translates requirements into research notes, data models, and implementation plans while validating against repository rules and updating project context.

When should I not use automated implementation plan generation?

You should not use automated implementation plan generation when your project lacks a SpecKit directory structure or established constitution rules, as the workflow depends on these predefined validation gates and context templates to produce valid engineering artifacts.
