What Should I Do Next?

Check these in order:

1. /chapter — main objective.
2. /quest — daily quest progress.
3. /checklist — available repeatable activities and cooldowns.
4. /state and /profile — current shinobi status.
5. /cooldowns — what you are waiting for.

If the main path is blocked by a resource or skill requirement, train/explore and inspect the related system guide rather than repeatedly retrying the same command.
