Refined Claude Extension

This Chrome extension adds the following enhancements to claude.ai:

1. Triggers a notification when Claude has finished responding. Also, the favicon changes grey while generation is happening, and then has a red dot when it is done, indicating you should check the window.
2. Auto-click "Continue" when it occurs (can be disabled)

Known bugs

• We will indefinitely click "Continue" if you hit the message limit and are simultaneously rate limited.

• When you start a fresh chat from the main screen, we don't seem to properly change the favicon to indicate we are generating. (This only happens intermittently.)

• There is some code for auto-approve tool use but it's broken right now, and difficult for me to test as Anthropic as (temporarily?) opted into some flow where tool approvals persist across chats.

Development Workflow

The extension has two build modes:

• Debug Mode: Includes additional permissions (scripting, activeTab) for development and testing
• Release Mode: Excludes these permissions for Chrome Web Store releases

To build the extension:

For Development (Debug Mode)

pnpm build:debug

For Release

pnpm build
# or
pnpm build:release

Then load the dist directory as an unpacked extension in Chrome.

Testing

Run tests with:

pnpm test

The tests replay rrweb recordings of claude.ai with the extension loaded and verify that the extension triggers appropriately, so they take a bit of time to run.
