Spec Kitty, a tool for Specification Driven Development (SDD) agentic projects, with kanban and git worktree isolation.
Project description
Spec Kitty
Spec-driven development for AI coding agents.
Spec Kitty is an open-source CLI for turning product intent into a repeatable agent workflow:
spec -> plan -> tasks -> next -> review -> accept -> merge
It keeps the important context in your repository, creates work packages that agents can execute, and uses git worktrees so implementation work can happen without constantly switching branches.
Is It For You?
Use Spec Kitty when:
- AI coding sessions are losing requirements, decisions, or acceptance criteria.
- You want specs, plans, tasks, reviews, and merge state stored in the repo.
- Multiple agents or developers need clear work package boundaries.
- You want a local workflow first, with optional hosted tracker and sync integrations later.
It is probably overkill for one-off edits, tiny scripts, or teams that do not use Git.
What It Provides
| Need | Spec Kitty provides |
|---|---|
| Start from intent | Guided specify, plan, and tasks workflows |
| Keep agents aligned | Repository-native mission artifacts under kitty-specs/ |
| Split implementation | Work packages with lifecycle lanes such as planned, in_progress, for_review, and done |
| Avoid branch chaos | Isolated git worktrees under .worktrees/ |
| See progress | Optional local kanban dashboard with spec-kitty dashboard |
| Integrate agents | Slash commands or skills for common AI coding tools |
Quick Start
Install the CLI:
pip install spec-kitty-cli
# or
uv tool install spec-kitty-cli
Create or initialize a project:
spec-kitty init my-project --ai claude
cd my-project
spec-kitty verify-setup
Replace claude with your agent key when needed. Common choices include codex, cursor, gemini, copilot, opencode, qwen, windsurf, kiro, and vibe.
Open your AI coding agent in the project and run the core workflow:
/spec-kitty.charter
/spec-kitty.specify Build a small task list app.
/spec-kitty.plan
/spec-kitty.tasks
Then let the runtime choose the next action until the mission is ready:
spec-kitty next --agent claude --mission <mission-slug>
Review, accept, and merge:
/spec-kitty.review
/spec-kitty.accept
/spec-kitty.merge --push
For the full walkthrough, see Your First Feature.
