# List Agent or harness runs

Use `agent__list_traces` with an `agent_...` or `harness_...` handle.

* Required input: `subject_id`.
* Optional inputs: `start_time_unix_seconds`, `end_time_unix_seconds`, `limit`, `cursor`, `sort`, `session_id`, and Gateway's `rationale`.
* Limit: accepts 1 to 100.
* Effect: read only.

Pass `cursor` back unchanged. For a subject the caller did not create, an
empty result can mean the caller has not run it.
