Specification-Driven Development methodology from GitHub spec-kit. Use when users ask to create specifications, plan features, define requirements, write user stories, decompose tasks, establish project constitution, or follow SDD workflow.
Implements Specification-Driven Development workflow to create specifications, plans, and executable tasks before coding.

LICENSE.txtreference/constitutional-articles.mdreference/workflow-guide.mdComprehensive implementation of GitHub's spec-kit methodology where specifications become executable, directly generating functional implementations.
Source: This skill is based on the official GitHub spec-kit project - an open-source toolkit that implements Specification-Driven Development.
When a user needs to develop a feature or start a project, follow this workflow:
/speckit.constitution)/speckit.specify)/speckit.clarify - optional)/speckit.plan)/speckit.tasks)/speckit.implement)Note: The official spec-kit includes slash commands for Claude Code integration. This skill provides the same workflow without requiring the CLI installation.
SDD Request → What stage?
│
├─ New Project / Feature
│ ├─ Create constitution.md (principles)
│ ├─ Write spec.md (requirements)
│ ├─ Run clarification (5 questions)
│ ├─ Generate plan.md (technical)
│ ├─ Create tasks.md (breakdown)
│ └─ Implement according to tasks
│
├─ Existing Specifications
│ ├─ Analyze consistency across artifacts
│ ├─ Identify gaps or ambiguities
│ └─ Suggest improvements
│
└─ Documentation Only
├─ Extract specifications from code
└─ Generate reverse-engineered docs
Spec-Kit inverts traditional development:
Specifications are the first artifact, and code is their expression in a particular language.
For complete details on each article with implementation examples and validation checklists, see Constitutional Articles.
Summary:
Critical: Article III (Test-First) is non-negotiable. Write failing tests first, verify they fail, then implement.
For complete details on each phase with templates, examples, and best practices, see Workflow Guide.
Establish immutable project principles in constitution.md.
Define WHAT to build and WHY (not HOW) in spec.md. Include:
Use [NEEDS CLARIFICATION] markers for ambiguities.
Ask 5 targeted questions to eliminate ambiguity before planning.
Define HOW to implement in plan.md with:
Ensure plan completeness:
Generate tasks.md with sequential phases:
Execute tasks following Test-First approach:
Automatically apply SDD methodology when users:
If the user has the spec-kit CLI installed, they can use these slash commands in Claude Code:
Core Workflow Commands:
/speckit.constitution - Establish governing principles and development guidelines/speckit.specify - Define functional requirements and user stories (focus on what, not how)/speckit.plan - Create implementation strategy with architecture and tech stack/speckit.tasks - Generate ordered task lists with dependencies and parallel execution markers/speckit.implement - Execute implementation following task breakdownEnhancement Commands:
/speckit.clarify - Resolve ambiguities with structured questioning (recommended before planning)/speckit.analyze - Validate cross-artifact consistency across specs, plans, and tasks/speckit.checklist - Generate quality validation checklist for requirement completenessInstallation:
# Install spec-kit CLI
uv tool install specify-cli --from git+https://github.com/github/spec-kit.git
# Initialize in current project
specify init . --ai claude
Note: This skill provides the same methodology without requiring the spec-kit CLI installation.
Activates when the user asks about AI prompts, needs prompt templates, wants to search for prompts, or mentions prompts.chat. Use for discovering, retrieving, and improving prompts.
