AgentsHarn
Use Harn in Kettu
Runs .harn agent pipelines as a native ACP coding agent. Kettu installs Harn the first time you use it; sign in once and it runs there: several sessions side by side, approval requests you spot at a glance.
- 1Sessions side by sideThe sidebar shows which one is running and which one is waiting for you
- 2Approval requestsThe command and the files to change, exactly as they are; answer with one key
Three steps
Install, sign in, start a session
- 01
Install
The first time you use it, Kettu downloads the version the ACP Registry lists into its own data directory.
- 02
Sign in
Sign in the way it offers: its own sign-in flow, or its sign-in command run in Kettu’s built-in terminal. It keeps the sign-in itself.
- 03
Start a session
Pick a project and Harn, and write what to do; several sessions can run side by side, each in its own worktree.
