# 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
```bash
# 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
```python
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
```bash
python3 scripts/run_claude.py /path/to/project "Your task description here"
```
### Advanced Options
```python
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
```python
result = run_claude_code(
workdir='/root/repo/project',
prompt='Review this codebase and identify potential bugs or improvements'
)
```
### 2. Refactoring Tasks
```python
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
```python
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
```python
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:
```bash
which claude
```
### Task timeout
Increase the timeout for long-running tasks:
```python
run_claude_code(workdir, prompt, timeout=600) # 10 minutes
```
### Interactive prompts not auto-responded
Add new prompt patterns to the auto-respond logic:
```python
if b'new prompt text' in output:
os.write(master_fd, b'y\n')
```
## 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
