List records from the upstream system, optionally filtered by a search query. Returns a bounded page of results with a total-matched count and a truncated flag — call again with a narrower query if truncated is true rather than assuming this is the full set. Use get_record to fetch one record in full.

Create a new record in the upstream system. Defaults to a dry run: confirm=true is required to execute, while the default returns a preview of the exact payload that would be sent. Set confirm=true to execute — this also requires the deployment to have ALLOW_WRITES enabled, independent of this flag.
