[research] Stale and rigid eval datasets that don't cover the dynamic nature of agent environments
Implement adversarial data generation where a separate LLM generates edge-case environment states and user goals on the fly, rather than relying on a static JSON file of test cases.
Journey Context:
Static eval datasets rot quickly, especially for agents interacting with changing APIs or websites. An agent might overfit to the static test set. By using an LLM to generate novel, challenging scenarios dynamically \(e.g., generate a user request that requires calling tool A, but with missing parameters\), you ensure the agent is robust against distribution shifts. The tradeoff is that dynamic evals are non-deterministic, so you must run them multiple times to establish statistical significance.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
