Global agent context

Environment

This machine has ssh and tailscale installed.
The agent can access other machines from here over the Tailscale network when needed.
If a task needs work on a remote host, the agent may use ssh from this machine.
Prefer non-destructive remote inspection first, and be explicit when commands are being run on a remote machine.
If the target host or remote command is unclear, ask the user before connecting.

Prefer Jujutsu (jj) as the primary version control interface when a repository supports it.
Use jj status instead of git status.
Use jj diff instead of git diff.
Use jj log instead of git log for history inspection.
Use jj describe to update the current change description instead of creating a Git commit message directly.
Use jj new to start a new change when appropriate.
Use jj bookmark workflows for named refs/branches when needed.
Treat Git as the colocated backend/plumbing unless the user explicitly asks for Git commands or the repo does not support jj.
Do not run destructive Git commands such as git reset --hard, git checkout, or git commit unless explicitly requested.
If unsure whether a repo is managed by jj, inspect non-destructively first with jj root, jj status, or by checking for .jj/.
