Command definition
browser-start.mddescription: Starts tandem's shared Chrome browser (dedicated profile, CDP on loopback). allowed-tools: Bash(tandem-browser *)
Starting tandem's shared browser:
!`tandem-browser start`
If you see "Chrome ready", the window is available: you control it with the mouse and Claude operates it via CDP. If it fails, check status with `/tandem:browser-status`.
Note: if you had just stopped a previous browser, the **first** browser command may report `Target page … has been closed` once — that is the (persistent) MCP reconnecting to the new (ephemeral) Chrome, not an error in your setup. Just retry; the second command works.
