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.
Plugin Marketplace Integration — Provides a catalog mechanism (cctools-plugins) to register and install reusable skills and workflow extensions. - Vendored Offline Skills — Bundles pinned upstream rule sets (such as agent-style and remove-ai-patterns) to ensure deterministic execution without external network dependencies. - Workflow Monitoring CLI — Includes tooling to supervise, certify, and manage execution states across multi-step agent operations. - Lifecycle Delivery Controls — Implements messaging and lifecycle hooks to harden automated agent task execution and PR interactions. - Zero-Dependency Evaluators — Leverages native Node.js scripts for validation and pattern detection without requiring heavy runtime package installations.
Use cases
Use Case: Enforcing Formal Technical Prose Developers load vendored writing skills into Claude Code sessions to automatically sanitize AI artifacts and enforce formal technical documentation guidelines across repository pull requests.
Use Case: Orchestrating Monitored Agent Workflows Teams utilize the built-in workflow monitoring CLI to track agent steps, inspect lifecycle delivery events, and ensure tasks complete deterministically.
Use Case: Offline and Air-Gapped Skill Deployment Engineers deploy pinned agent plugins in restricted or CI environments where external package downloads are disabled, guaranteeing identical skill execution.
Who it is for
This tool is built for developers and engineering teams actively using the Claude Code CLI who want to extend it with reproducible plugins, workflow automation, and rule enforcement. It is not intended for users looking for an all-in-one standalone IDE or non-Claude agent frameworks.
Install guide
Installation Clone the repository and install project dependencies using npm ci to respect locked package versions: bash git clone https://github.com/pchalasani/claude-code-tools.git cd claude-code-tools npm ci
First Run Ensure Node.js is configured on your system path, and verify the available plugins and marketplace configuration: bash # Inspect marketplace manifests cat .claude-plugin/marketplace.json
Example Session Run an agent task or execute deterministic skill routines using the repository scripts: bash # Execute an agent-assisted workflow node scripts/update-upstream.sh(Note: Plugin invocation and workflow commands integrate directly with your local Claude Code CLI environment.)
