Understanding the OpenClaw 'cc' Skill: Your Gateway to Claude Code Relay
In the rapidly evolving world of developer productivity tools, the OpenClaw
project stands out as a modular, extensible ecosystem. One of its most
critical components is the cc (Claude Code) skill. If you have been
wondering how to bridge your local development environment with the powerful
capabilities of Claude Code, this guide is for you. We will break down exactly
what this skill does, how it works, and why it is a game-changer for your
daily workflow.
What is the OpenClaw 'cc' Skill?
The cc skill is a short slash command wrapper designed to facilitate
seamless interactions with Claude Code relay sessions. Think of it as your
command center for managing AI-driven coding sessions directly within your
terminal or interface. Instead of juggling multiple windows or manually
configuring relay connections, the cc skill provides a unified, concise
interface to initiate, manage, and terminate sessions on a project-by-project
basis.
The Power of Command Routing
At its core, the cc skill is built on a robust command routing system that
interprets user intent and executes the corresponding logic via
scripts/cc.sh. Here is a breakdown of the primary commands you will use most
often:
- /cc projects: This command lists all available projects, pulling data from your local map and project root. It is the perfect way to get an overview of what you are currently working on.
- /cc on [project]: This is the activation command. It starts or reuses a Claude session, using fuzzy matching to find your target project directory. Once initiated, you enter the critical 'relay mode.'
- /cc off [project]: When you are finished, this command gracefully stops the session, allowing you to move on to your next task without leaving background processes running.
- /cc tail [project] [lines]: Need to see what happened in the last few minutes? The tail command pulls recent output from your session, with a default view of 120 lines to keep your workspace clean.
- /cc status: This provides a quick snapshot of all active relay sessions, ensuring you stay organized.
The Relay Mode Contract: A Transparent Pipe
The most important concept to grasp when working with the cc skill is the
'relay mode' contract. Once you execute /cc on [project], the system enters
a specific state. In this mode, the OpenClaw cc skill acts as a transparent
pipe between you and Claude Code.
This means that all your user messages are forwarded directly to the AI. The
skill is strictly prohibited from interpreting, answering, or acting on these
messages itself. By design, it does not try to be 'helpful' in a way that
interferes with the AI's logic; it simply delivers the prompt to Claude Code
and returns the final output to you. This ensures that you get the raw,
powerful insights of the Claude model without any middleware interference.
Why This Architecture Matters
By enforcing this strict separation of concerns, the OpenClaw cc skill
ensures reliability. You do not have to worry about the 'middleman'
hallucinating or getting in the way of your code generation. Furthermore, by
handling tool calls and menu interactions as inline buttons, the skill keeps
your terminal output readable and navigable. Whether you are dealing with
complex debugging tasks or scaffolding new features, this approach keeps the
developer-to-AI feedback loop incredibly tight.
Getting Started: Environment Configuration
To get the most out of the cc skill, you should be aware of the environment
variables that govern its behavior. These can be adjusted to match your
specific system setup:
- CLAUDE_RELAY_DIR: Automatically detected, this points to your specific claude-relay skill directory.
-
CLAUDE_RELAY_ROOT: Defaults to
$HOME/projects. This is the root directory where the tool searches for your active work. - CLAUDE_RELAY_MAP: Points to your project alias map file, allowing you to create custom shorthand for your project folders.
Best Practices for Efficient Workflow
To maximize your efficiency, we recommend treating your terminal like a
dedicated conversation space. Start by listing your projects with /cc, jump into a session with
projects/cc on, and rely on the status checks to
prevent session bloat. If you find yourself needing to switch contexts, simply
execute /cc off to clean up the previous session before starting a new one.
Remember, the cc skill is designed to move at the speed of your
thoughts—keep your commands brief, and let the relay mode do the heavy
lifting.
Conclusion
The cc skill in OpenClaw is more than just a wrapper; it is an essential
piece of infrastructure for anyone serious about AI-assisted development. By
providing a clean, reliable, and transparent interface for Claude Code, it
removes the friction of session management and allows you to focus on what
really matters: writing high-quality code. Explore the GitHub repository,
install the necessary dependencies, and start integrating Claude Code into
your local environment today. Your productivity will thank you.
