Project overview

cc-sdd installs a spec-driven development workflow as Agent Skills, moving from discovery, requirements, and design into task generation and long-running implementation. Each task can be handled by a fresh implementer using test-driven development, followed by an independent reviewer and an automatic debugging pass. The same seventeen skills target eight coding agents and thirteen languages; Claude Code and Codex are stable, while the other integrations remain beta.
