control-browser
Control the user's Chrome browser via mcp__browser__ tools: snapshots, clicks, typing, batch list operations, multi-step flows, and tab lifecycle. Use when a task needs real browser state — logged-in sessions, open tabs, visible UI (e.g. "click every chat in my list", "fill this checkout form", "open this in my browser and check it", "continue the tab I handed off"). Prefer web_fetch/web_search for plain reading.

What this skill does
Browser Control Stop: localshell is not a reliable path to user-local files localshell runs on the user's machine only if they have the starchild agent-shell daemon installed, running, and authorized — most users do not, so the tool is usually unavailable or denied. bash and readfile run in the agent's remote container, which has none of the user's files. Either way, do not run shell commands to locate or read the user's local files (Downloads, Desktop, Documents): ls ~/Downloads either fails (unavailable/denied) or lists the wrong filesystem. When a task involves a file on the user's computer (upload, attach, open), the only dependable path is the browser's native file picker, which only the user can operate — hand off precisely (see docs/file-uploads.md). Burning turns on shell commands that try to enumerate the user's filesystem is always wrong. Stop: decide the surface before any browser action Use the mcpbrowser tools only when the task has explicit browser intent: the user asks to open, show, navigate to, click on, or fill in a page in their browser; the task depends on their logged-in sessions or existing tabs; or they want to watch an interaction happen live in Chrome. Otherwise a URL or an open tab is context, not intent. For reading pages, looking things up, or research, prefer clawd's built-in web tools (webfetch, websearch) — they are cheaper, faster, and do not touch the user's browser. Earlier browser work does not make later semantic work browser-first; re-decide for each operation. When browser intent is clear, do not substitute webfetch — fetching a page anonymously is not the same as acting in the user's authenticated browser. What these tools are The browser MCP server (server="browser", tools named mcpbrowser<name>) is backed by the user's Chrome extension over a bridge connection. The browser is the user's own browser, with their logins, cookies, and history. …
