What This Skill Does

Cc is a Communication & Messaging skill for OpenClaw by artwalker.

cc — Claude Code Relay

Operate Claude Code remotely from any OpenClaw channel via tmux.

Continues your existing claude -c sessions — ACP creates new sessions, cc connects to what's already running.

Language: Always reply in the same language the user uses.

Script

{baseDir}/scripts/cc.sh <command> [args...]

Commands

Command Action
/cc on <project> Start session (claude -c in project dir)
/cc off [project] Stop session
/cc ? Check Claude Code status (running/idle/dead)
/cc tail [project] [lines] Show recent output
/cc projects List available projects
/cc status List active sessions
/cc config root <path> Set project root directory
/cc Show help + project list
/cc <message> Send message to Claude Code

Relay Mode (CRITICAL)

After /cc on <project>, you enter relay mode:

  1. ALL user messages are forwarded to Claude Code — NEVER answer yourself
  2. Only messages NOT forwarded: /cc off, /cc ?, /cc tail, /cc status, /cc projects, /cc config
  3. Relay mode ends on /cc off

You are a transparent pipe. Never interpret, analyze, or answer the user's question yourself.

Starting a Session

  1. Run: scripts/cc.sh on <project>
  2. Report to user:
    ✅ Claude Code session started for <project>
    Your messages will now be sent directly to Claude Code.
    Send /cc off to exit relay mode.
    
  3. Enter relay mode

Sending Messages (relay flow)

When user sends a message in relay mode:

  1. Immediately reply: ⏳ (so user knows message was received)
  2. Forward: scripts/cc.sh <project> "<user's message>"
  3. The script returns the incremental output — only content from this reply, not history
  4. Return output to user (see Output Formatting below)

Stopping a Session

  1. Run: scripts/cc.sh off <project>
  2. Report to user:
    Session ended. You're back to normal chat.
    

Status Check (/cc ?)

Run: scripts/cc.sh check <project>

Report result to user:

  • "🟢 Claude Code is running and waiting for input"
  • "🔄 Claude Code is processing..."
  • "🔴 Claude Code process died — try /cc off then /cc on to restart"
  • "⚪ No active session"

/cc (no arguments)

Run scripts/cc.sh projects. Show brief help + project list.

If there's a last-used project (marked with ★), show it first. Keep the response short — just names, no paths.

First-time Setup

When scripts/cc.sh projects outputs SETUP_NEEDED (exit 100):

  1. Check: which tmux and which claude — report if missing
  2. Ask user: "Where are your projects? (e.g., ~/projects)"
  3. Run: scripts/cc.sh config root <their-answer>
  4. List projects to confirm

Output Formatting

If output ≤ 4000 characters: wrap in one code block and send.

If output > 4000 characters: send a summary of the key output (first meaningful paragraph + last 10 lines), then add: "Full output: send /cc tail to see more"

Always: strip ANSI escape codes (the script handles this automatically).

Requirements

  • tmux installed
  • claude CLI installed (npm i -g @anthropic-ai/claude-code)
  • Any OpenClaw channel (Telegram, Discord, CLI, etc.)
