architect-create-simulation-test

Use when the user wants a full multi-turn conversation test where a simulated user talks to the agent across many turns. Fires on "test the whole flow", "simulate a caller", "write a scenario test", "test that the agent handles an upset customer / a full booking / a multi-step call", or when a simulation-test creation attempt failed. For single-response checks use the LLM-test skill; for one tool call use the tool-test skill.
