ClaudeMonkey
ClaudeMonkey is a fork of Violentmonkey (MIT, by Gerald). It keeps the full userscript manager but makes the default action a textbox: you describe how you want the current site changed, and a locally-running Claude Code instance writes or edits the userscript for that site (using your Claude subscription via a native-messaging bridge — see
bridge/). Setup and usage instructions are in SETUP.md. All credit for the underlying userscript engine goes to the Violentmonkey authors; the original README follows.
Violentmonkey
Violentmonkey provides userscripts support for browsers. It works on browsers with WebExtensions support.
