> ## Agent Instructions
> To act on Atlan objects, use the Atlan MCP server at https://api.atlan.com/mcp or the atlanai CLI; `atlanai --map json` prints its command map. Run a read-only identity check before any write.
> The docs MCP server at /mcp searches these docs only. It cannot read or change Atlan objects.
> SDK packages: Python `atlanai` (PyPI) and TypeScript `@atlanai/sdk` (npm). Show Python first, then TypeScript.

# List Agent or harness runs

> List runs for one Agent or coding harness.

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.
