cc-sdd is a spec-driven development (SDD) harness distributed as a skill pack for coding agents. It ships Agent Skills plus agents.md and claude.md files, aimed at turning approved specs into long-running autonomous implementation across tools like Claude Code, Codex, Cursor, Copilot, Windsurf, OpenCode, Gemini CLI, and Antigravity.

You want a minimal, adaptable SDD workflow you can drop into whichever coding agent you already use.

Use it to

  • Run spec-driven development with Claude Code
  • Turn approved specs into autonomous implementation runs
  • Adapt the harness across multiple coding agents
  • Use steering and subagent skills in your workflow
