• ~/.claude/local/claude (default)
• Custom path specified via the claude_path option

Make sure you have Claude Code installed and configured before using this plugin.

Usage

Available Models

This plugin provides five models:

• code/sonnet - Claude Code with latest Sonnet model (default)
• code/opus - Claude Code with latest Opus model
• code/sonnet-4 - Claude Code with Sonnet 4 (claude-sonnet-4-20250514)
• code/opus-4 - Claude Code with Opus 4 (claude-opus-4-20250514)
• code/opus-4.1 - Claude Code with Opus 4.1 (claude-opus-4-1-20250805)

llm models list

Basic Usage

Execute a prompt using Claude Code Sonnet:

llm -m code/sonnet "Explain how to use Python decorators"

Execute a prompt using Claude Code Opus:

llm -m code/opus "Write a Python function to calculate fibonacci numbers"

Execute a prompt using Claude Code Sonnet 4:

llm -m code/sonnet-4 "Review this code for best practices"

Model Options

The plugin supports the following options:

• claude_path: Custom path to the Claude Code CLI executable

Example using a custom Claude Code path:

llm -m code/sonnet -o claude_path /usr/local/bin/claude "Your prompt here"

File Attachments

This plugin supports attaching various file types to your prompts, including:

• Text files (.txt, .py, .js, .html, .css, .md, etc.)
• Code files (Python, JavaScript, C, Java, Shell scripts)
• Data files (JSON, XML, YAML)
• Images (PNG, JPEG, GIF, WebP)

Attach files using the -a flag:

llm -m code/sonnet -a myfile.py "Explain this Python code"

Attach multiple files:

llm -m code/sonnet -a file1.py -a file2.js "Compare these two implementations"

URL Support

When URLs are included in prompts or attachments, the plugin automatically enables the WebFetch tool for Claude Code:

llm -m code/sonnet "Analyze the content at https://example.com"

Interactive Chat

Start an interactive chat session:

llm chat -m code/sonnet

Or with Opus:

llm chat -m code/opus

Or with Sonnet 4:

llm chat -m code/sonnet-4

Configuration

You can set the Claude Code path permanently using LLM's configuration:

llm logs path  # Find your logs directory
# Edit the config file to set default claude_path

Features

• Five Model Support: Access latest Sonnet/Opus and specific versioned models (Sonnet 4, Opus 4, Opus 4.1)
• File Attachments: Support for text, code, data, and image files
• URL Processing: Automatic WebFetch tool enablement for URL analysis
• Streaming Support: Real-time response streaming
• Error Handling: Comprehensive error reporting and timeout management
• Flexible Path Configuration: Custom Claude Code executable paths

Technical Details

• Timeout: Commands timeout after 5 minutes to prevent hanging
• Temporary Files: Attachment content is safely handled via temporary files
• Error Recovery: Graceful handling of missing executables and other errors
• Content Types: Extensive MIME type support for attachments

Troubleshooting

Claude Code CLI Not Found

If you see an error about the Claude Code CLI not being found:

1. Ensure Claude Code is installed and accessible
2. Check that the executable is at ~/.claude/local/claude or specify a custom path
3. Verify the executable has proper permissions

Example with custom path:

llm -m code/sonnet -o claude_path /path/to/your/claude "Your prompt"

Timeout Issues

If commands are timing out:

• Complex prompts may take longer to process
• Large file attachments can increase processing time
• The default timeout is 5 minutes

File Attachment Issues

If file attachments aren't working:

• Ensure files exist and are readable
• Check that file types are supported
• Large files may cause performance issues

Development

To set up this plugin for development:

git clone https://github.com/paradise-runner/llm-claude-code.git
cd llm-claude-code-plugin
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -e .

The plugin uses Python's subprocess module to execute the Claude Code CLI and supports:

• Multiple attachment types through MIME type detection
• Streaming responses via generator functions
• Configurable command paths and options
• Robust error handling and cleanup
