When to use
Use this skill when the user needs automated tests for an AI agent's behavior: "write tests for my agent," "test that it handles tool failures," "make sure it recovers from errors," "stress-test the agent before launch." Trigger phrases: agent tests, test harness, edge-case testing, adversarial testing, multi-turn tests, agent recovery tests, property testing.
Do NOT use it for evaluating quality on a task suite (that's the eval framework skill — evals measure performance; tests verify behavior and contracts). Use this when the goal is a runnable, automated test suite that catches regressions in agent behavior, especially on edge cases and failure paths.
