llm-tools-patch

LLM plugin for Simon Willison's llm providing text file manipulation, including reading, writing, and edits.

Installation

Install this plugin in the same environment as LLM. You'll need at least LLM 0.26a1 or later.

From PyPI (recommended)

llm install llm-tools-patch

From source

git clone https://github.com/dannyob/llm-tools-patch
cd llm-tools-patch
llm install .

⚠️ Security Warning

This plugin provides AI agents with direct file system access. The tools can read, write, and modify files within your current working directory. Before enabling this plugin:

• File access is restricted to the working directory where you run the llm command
• Only use with trusted AI models and prompts
• Use --ta (tool approval) mode - review all file operations carefully
• Consider the potential impact if an AI agent modifies important files

Usage

The plugin provides a single Patch toolbox with five core operations:

Available Tools

• read - Read complete contents of a text file
• write - Write new content to a file (overwrites existing)
• edit - Make a single string replacement
• multi_edit - Apply multiple string replacements in sequence
• info - Get file metadata and information

Basic Usage

# Make a single edit
llm prompt -m gpt-4o-mini "Change port 8080 to 3000 in config.txt" --tool Patch --ta

# Make multiple edits
llm prompt -m gpt-4o-mini "Add a smiley face to the first heading in README.md, then a thank you emoji to the last heading" --tool Patch --ta --chain-limit 0

Recommended Options

For interactive use, combine these flags:

• --ta - Requires user confirmation before executing functions (safety)
• --chain-limit 0 - Allows unlimited tool calls in one session (default is 5)
