claude-code-runner（Claude 代码 runner）

Claude Code Runner

Overview

A wrapper skill for running Claude Code programmatically in non-interactive environments. Uses PTY (pseudo-terminal) to handle TTY-required operations and automatically responds to confirmation prompts.

Features

• PTY-based execution: Works in non-TTY environments (containers, CI/CD, background processes)
• Auto-respond to prompts: Automatically answers "Do you want to..." confirmations
• User switching: Runs as specified non-root user
• File synchronization: Copies project to temp directory, executes, syncs changes back
• Timeout handling: Configurable timeout with proper cleanup
• Output capture: Captures and returns full stdout/stderr

Installation

# Clone the skill
git clone https://github.com/lhl09120/claude-code-runner-en.git

# Make script executable
chmod +x claude-code-runner-en/scripts/run_claude.py

Usage

Basic Usage

from claude_code_runner import run_claude_code

result = run_claude_code(
    workdir='/path/to/project',
    prompt='Refactor the authentication module to use JWT tokens',
    user='lighthouse',
    timeout=300
)

print(result)

Via Command Line

python3 scripts/run_claude.py /path/to/project "Your task description here"

Advanced Options

result = run_claude_code(
    workdir='/root/repo/my-project',
    prompt='''
    1. Review the codebase
    2. Identify security vulnerabilities
    3. Fix any issues found
    4. Add appropriate tests
    ''',
    user='developer',
    timeout=600  # 10 minutes
)

API Reference

run_claude_code(workdir, prompt, user='lighthouse', timeout=300)

Execute a Claude Code task in a PTY environment.

Parameters:

• workdir (str): Working directory containing the project
• prompt (str): Natural language task description
• user (str): User to run as (default: 'lighthouse')
• timeout (int): Timeout in seconds (default: 300)

Returns:

• str: Combined stdout and stderr output

Behavior:

1. Copies project to temporary directory
2. Changes ownership to specified user
3. Executes Claude Code via PTY
4. Auto-responds to confirmation prompts
5. Syncs changes back to original directory
6. Cleans up temporary files

Use Cases

1. Automated Code Review

result = run_claude_code(
    workdir='/root/repo/project',
    prompt='Review this codebase and identify potential bugs or improvements'
)

2. Refactoring Tasks

result = run_claude_code(
    workdir='/root/repo/legacy-app',
    prompt='Refactor the database layer to use SQLAlchemy ORM instead of raw SQL'
)

3. Adding Features

result = run_claude_code(
    workdir='/root/repo/api-service',
    prompt='''
    Add a new REST endpoint for user profile management:
    - GET /api/users/{id}/profile
    - PUT /api/users/{id}/profile
    - Include validation and error handling
    - Add unit tests
    '''
)

4. Bug Fixes

result = run_claude_code(
    workdir='/root/repo/web-app',
    prompt='Fix the memory leak in the WebSocket connection handler'
)

Requirements

• Python 3.8+
• Claude Code installed and in PATH
• Unix-like environment (Linux/macOS)
• Root or sudo access (for user switching)

Configuration

Environment Variables

• CLAUDE_CODE_USER: Default user to run as (default: 'lighthouse')
• CLAUDE_CODE_TIMEOUT: Default timeout in seconds (default: 300)

Customization

Edit scripts/run_claude.py to customize:

• Auto-response keywords
• Temp directory location
• Sync behavior
• Output formatting

Troubleshooting

"Permission denied" errors

Ensure the script is run with sufficient privileges to:

• Create temporary directories
• Change file ownership
• Switch to target user

Claude Code not found

Make sure Claude Code is installed and in the system PATH:

which claude

Task timeout

Increase the timeout for long-running tasks:

run_claude_code(workdir, prompt, timeout=600)  # 10 minutes

Interactive prompts not auto-responded

Add new prompt patterns to the auto-respond logic:

if b'new prompt text' in output:
    os.write(master_fd, b'y\
')

Limitations

• Requires Unix-like environment (uses PTY)
• Requires root/sudo for user switching
• Claude Code must be installed separately
• May not handle all edge cases of interactive prompts
