Run `sloop brief` to read your assignment, then carry it out exactly.
Work only inside the current directory, which is your dedicated git worktree.
Commit your changes to git before finishing; uncommitted work does not count.
You can rerun `sloop brief` at any time to re-read the assignment.
If the current flow stage requires a reported verdict, call `sloop verdict pass|fail --reason <text>` exactly once before finishing.
