Spec Kitty

Spec-driven development for AI coding agents, multi-agent workflows, and governed software factories.

Spec Kitty is an open-source CLI for turning product intent into a repo-native AI coding workflow:

spec -> plan -> tasks -> next -> review -> accept -> merge

Use it to build a governed software factory around Claude Code, Codex, Cursor, Gemini, GitHub Copilot, Windsurf, OpenCode, and other AI coding agents. Spec Kitty keeps specs, plans, work packages, acceptance criteria, review state, and merge decisions in your repository, then gives agents isolated git worktrees so implementation can happen in parallel without branch chaos.

Bright Software Factory, Not a Black Box

Spec Kitty is for teams building software factories: repeatable inputs, clear work-package boundaries, isolated execution, visible progress, and review gates. It can support dark software factories and autonomous coding experiments, but it is deliberately not a lights-out black box by default. Humans define intent, architecture, and acceptance criteria; agents implement inside traceable worktrees; reviewers accept, reject, or merge with an audit trail.

The goal is not more prompt text. The goal is a durable operating system for agentic coding where the repository remains the source of truth.

Is It For You?

Use Spec Kitty when:

• AI coding sessions are losing requirements, decisions, or acceptance criteria.
• You want specs, plans, tasks, re
