Managing work with `nytid todo`

Identity: always use `--who dan-claude`

Every nytid todo command defaults to the current system user (dbosk). Pass --who dan-claude on every invocation — listing, adding, starting, completing, everything. Forgetting this flag means reading or modifying the wrong person's tasks.

Omitting or widening --who is acceptable when reading tasks to get context (see "Getting context from other assignees" below). Never modify tasks that are not assigned to dan-claude.
