Claude Code Skill for OpenClaw

Call Claude Code CLI from OpenClaw to read codebase, edit files, run commands, and automate coding tasks.

Overview

This skill provides integration with Claude Code CLI, allowing OpenClaw to leverage Claude Code's powerful coding capabilities including:

• Reading and understanding codebases
• Editing files with AI assistance
• Running terminal commands
• Creating commits and PRs
• Code review and debugging
• Running sub-agents for parallel tasks

Prerequisites

1. Install Claude Code CLI:

   curl -fsSL https://claude.ai/install.sh | bash
   

2. Authenticate:

   claude auth login
   

3. Verify installation:

   claude --version
   

Usage

Basic Query

Ask Claude Code a question about your codebase:

/claude-code What does the auth module do?

Run a Task

Execute a coding task:

/claude-code write tests for the login function

Continue Previous Session

Resume the most recent conversation:

/claude-code --continue

Resume Specific Session

Resume a session by name or ID:

/claude-code --resume auth-fix

Code Review

Review code changes:

/claude-code review the recent changes

Create Commit

Commit changes with a descriptive message:

/claude-code commit my changes

Integration with OpenClaw

This skill is designed to work with OpenClaw's exec tool. Here's how it integrates:

Method 1: Direct CLI Execution

Use OpenClaw's exec tool to run Claude Code commands:

claude -p "What files were changed in the last commit?"

Method 2: Session Management

Manage Claude Code sessions through OpenClaw:

# Continue last session
claude -c

# Resume specific session
claude -r my-session "Continue working on the feature"

Method 3: MCP Integration

For advanced integration, configure MCP servers:

claude mcp add \x3Cserver-name> \x3Cconfig>

Examples

Example 1: Explore a New Codebase

/claude-code Explore the project structure and tell me what the main components are

Example 2: Fix a Bug

/claude-code Find and fix the login bug - users can't log in with correct credentials

Example 3: Write Tests

/claude-code Write unit tests for the payment module

Example 4: Refactor Code

/claude-code Refactor the auth middleware to use async/await

Example 5: Code Review

/claude-code Review this PR for security issues

Example 6: Batch Operations

/claude-code /batch migrate all API endpoints to use the new error handler

Troubleshooting

Authentication Issues

# Check auth status
claude auth status

# Re-authenticate
claude auth login

Permission Issues

# Run with specific permission mode
claude --permission-mode plan "task"

Session Issues

# List available sessions
claude --resume

# Fork a session (create new)
claude -r old-session --fork-session "new task"

Advanced Features

Sub-agents

Run multiple Claude Code instances in parallel:

claude --agents '{
  "reviewer": {
    "description": "Code reviewer",
    "prompt": "You are a senior code reviewer",
    "tools": ["Read", "Grep", "Bash"]
  }
}'

Hooks

Automate actions before/after Claude Code runs:

See Hooks documentation

MCP Servers

Connect Claude Code to external tools:

claude mcp add github '{"github_token": "..."}'
