Overview
Spec Kitty is a Python CLI that stores specs, plans, work packages and review state in the repository under kitty-specs/. It installs slash commands or skills for agents such as Claude Code, Codex, Cursor, Gemini and Copilot, and gives each work package its own git worktree so agents can work in parallel. Work moves through a spec, plan, tasks, next, review, accept, merge loop.
Who it is for: Teams running several AI coding agents who want repo-based specs and gates
Strengths
- Keeps specs, tasks, review and merge state in Git rather than in chat history
- Isolated git worktrees under .worktrees/ per work package for parallel agents
- Supports many agents, including Claude Code, Codex, Cursor, Gemini, Copilot, Windsurf, OpenCode
- Local-first; README states no SaaS service is required
Weaknesses
- 4.x line is a release candidate; stable launch acceptance is stated as pending
- Hosted auth, sync and tracker flows were removed from open-core
- Overkill for one-off edits, small scripts or teams not using Git
- Does not write code itself; depends on a separate coding agent
What it needs
- no GPU
- Needs Python 3.11+, Git, An AI coding agent (Claude Code, Codex, Cursor, etc.)
- Models: Claude Code, Codex, Cursor, Gemini, GitHub Copilot
