Sidekick Agent door sidekick browser extension

Sidekick Agent is a lightweight companion extension for the Sidekick desktop agent. It sends the active tab’s URL and page title to the locally running Sidekick agent so your workflow capture includes full browser context alongside native application activity.

All communication is local via Native Messaging — no data is sent to external servers by this extension. The Sidekick desktop agent must be installed and running on your computer.
