Since we are starting the coder agent in the tmpdir, SFTP sessions also start in that folder.

Arguably, the session should start in$HOME because this is my experience with OpenSSH and it's more useful when doingsftp followed byls (list files) or doing something with home-relative paths.

sftp coder.work.mainConnected to coder.work.main.sftp> pwdRemote working directory: /tmp/coder.KnYnxH

There are (potentially) two ways to fix this:

1. Runos.Chdir in an early part ofcoder agent startup to change the default working directory by anything started by the agent
2. Switch outsftp.Server forsftp.RequestServer (e.g.sftp.NewRequestServer(session, sftp.InMemHandler(), sftp.WithStartDirectory(os.Getenv("HOME"))))

Re: 2, I don't know ifsftp.RequestServer can work as a drop-in replacement, the documentation is quite vague.

Definition of done

• The user lands in$HOME when usingsftp
