Claude Code Wrapper

A convenience wrapper that eliminates the friction of calling Claude Code from OpenClaw sessions.

Problem It Solves

When calling Claude Code through exec tools, environment variables from ~/.claude/config.json are not automatically loaded, resulting in “Not logged in” errors. This wrapper:

1. Auto-loads credentials from ~/.claude/config.json
2. Exports required env vars automatically
3. Provides seamless execution without manual setup

Usage

Basic Usage

Use the wrapper script directly:

bash pty:true command:"~/.openclaw/skills/claude-code-wrapper/scripts/claude_code.sh 'Your prompt here'"

With Working Directory

bash pty:true workdir:~/myproject command:"~/.openclaw/skills/claude-code-wrapper/scripts/claude_code.sh 'Analyze this codebase'"

Background Mode

bash pty:true workdir:~/myproject background:true command:"~/.openclaw/skills/claude-code-wrapper/scripts/claude_code.sh 'Run tests'"

Required Parameters

• pty:true — Claude Code is an interactive TUI application and requires pseudo-terminal mode
• Timeout — Recommend timeout:120 or longer for complex tasks

Environment Variables Auto-Loaded

The wrapper reads and exports these from ~/.claude/config.json:

• ANTHROPIC_AUTH_TOKEN
• ANTHROPIC_BASE_URL
• API_TIMEOUT_MS

Example Workflows

One-shot Code Generation

bash pty:true command:"~/.openclaw/skills/claude-code-wrapper/scripts/claude_code.sh 'Write a Python function to calculate Fibonacci numbers'"

Project Analysis

bash pty:true workdir:~/myproject timeout:180 command:"~/.openclaw/skills/claude-code-wrapper/scripts/claude_code.sh 'Review the architecture of this project and suggest improvements'"

Background Task with Monitoring

# Start background session
bash pty:true workdir:~/myproject background:true command:"~/.openclaw/skills/claude-code-wrapper/scripts/claude_code.sh 'Refactor the auth module'"

# Monitor progress
process action:log sessionId:XXX

# Kill when done
process action:kill sessionId:XXX

Prerequisites

1. Claude Code installed (claude command available)
2. Claude Code configured (~/.claude/config.json exists with valid credentials)
3. User has previously logged in to Claude Code manually

Error Handling

• Config not found: Script exits with error message if ~/.claude/config.json is missing
• Claude not installed: Script exits with error message if claude command not found
• Invalid token: Claude Code itself will report authentication errors

Notes

• This wrapper does NOT handle the “trust this directory” interactive prompt. For new directories, Claude Code may still ask for confirmation.
• For fully automated workflows, consider running Claude Code once manually in target directories to establish trust.
