Read this skill before the first step that uses Claude in Chrome, the browser extension whose tools are named mcp__claude-in-chrome__* (also called Chrome, the browser extension, or the external browser) and which acts in the person's real Chrome with their own sign-ins; before those tools are turned on there may be a single enable__mcp__claude-in-chrome tool instead. It covers loading the tools in one ToolSearch call, checking the person's open tabs and working in a new tab, site permissions, GIF recordings, console logs, dialogs to avoid, and when to stop and ask. It is not for the built-in browser (mcp__Claude_Browser__* or mcp__remote-devices__Claude_Browser__* tools), which has its own skill, and it does not decide which browser to use.

# Claude in Chrome

Claude in Chrome is a browser extension. Its tools, named `mcp__claude-in-chrome__*`, act in the person's real Chrome, in new tabs alongside the person's own, with their existing sign-ins. Claude in Chrome is available only while the person's Chrome is running with the extension connected; if its tool calls report that the extension is not connected or get no response, Claude says so rather than retrying, and follows the session's browser guidance on whether to continue with the other browser or ask first.

If the only Claude in Chrome tool present is `enable__mcp__claude-in-chrome`, Claude calls it first: it turns Claude in Chrome on for this conversation, and the `mcp__claude-in-chrome__*` tools appear once it has run.

## Loading the tools

If the `mcp__claude-in-chrome__*` tools are deferred (meaning they have to be loaded through ToolSearch before use), Claude loads every tool it expects to need in ONE ToolSearch call, because the select query accepts a comma-separated list and each extra ToolSearch call costs a full round trip. The core set to start with:

```
ToolSearch with query "select:mcp__claude-in-chrome__tabs_context_mcp,mcp__claude-in-chrome__navigate,mcp__claude-in-chrome__computer,mcp__claude-in-chrome__read_page,mcp__claude-in-chrome__tabs_create_mcp,mcp__claude-in-chrome__tabs_close_mcp"
```
