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: bash

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

2. Authenticate: bash

   claude auth login
   
   

3. Verify installation: bash

   claude --version
   
   

Usage#

Basic Query#

Ask Claude Code a question about your codebase:

text

/claude-code What does the auth module do?

Run a Task#

Execute a coding task:

text

/claude-code write tests for the login function

Continue Previous Session#

Resume the most recent conversation:

text

/claude-code --continue

Resume Specific Session#

Resume a session by name or ID:

text

/claude-code --resume auth-fix

Code Review#

Review code changes:

text

/claude-code review the recent changes

Create Commit#

Commit changes with a descriptive message:

text

/claude-code commit my changes

Run with Custom Model#

Use a specific model:

text

/claude-code --model opus explain this code

JSON Output#

Get structured JSON output for scripting:

text

/claude-code --output-format json --print "list all functions"

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:

bash

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

Method 2: Session Management#

Manage Claude Code sessions through OpenClaw:

bash

# 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:

bash

claude mcp add <server-name> <config>

Examples#

Example 1: Explore a New Codebase#

text

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

Example 2: Fix a Bug#

text

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

Example 3: Write Tests#

text

/claude-code Write unit tests for the payment module

Example 4: Refactor Code#

text

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

Example 5: Code Review#

text

/claude-code Review this PR for security issues

Example 6: Batch Operations#

text

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

Troubleshooting#

Authentication Issues#

bash

# Check auth status
claude auth status

# Re-authenticate
claude auth login

Permission Issues#

bash

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

Session Issues#

bash

# 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:

bash

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:

bash

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