Generates adversarial test cases targeting safe-failure behavior — refusals, hedging, graceful degradation. Use this when you want to stress-test an agent's safety boundaries, check for prompt injection, or build an adversarial eval set. Pairs with agent-eval for scoring: agent-redteam generates cases, agent-eval runs and scores them. Triggers on "red team my agent," "test for jailbreaks," "adversarial cases," "prompt injection testing," or "does my agent refuse correctly.

From the source SKILL.md

Generates adversarial inputs designed to expose unsafe, over-compliant, or brittle failure modes. The complement to agent-eval's correctness testing — here, a "pass" means the agent refused, hedged, or degraded gracefully.
