Claude Code Tools (cctools) is an open-source orchestration harness and plugin distribution toolkit developed by Prasad Chalasani (pchalasani). It is built to extend Anthropic's Claude Code CLI ecosystem with modular plugins, workflow automations, and governance skills. In standard use, the project acts as a management layer that supplies custom plugins and deterministic scripts to Claude Code. It allows developers to register and invoke specialized skills—such as technical writing linters, PR lifecycle management tools, and workflow monitors—directly within the agent's execution context. What differentiates Claude Code Tools is its focus on reproducible, offline-capable agent capabilities. Rather than relying on unpinned dynamic downloads, it vendors upstream skill rules and deterministic Node.js evaluators, ensuring that agent behavior remains consistent across different developer environments and CI runs. The project is available as open-source software on GitHub with an active commit history and versioned release cycle.
