Tool-Calling Agent Testing

The hardest agent bugs are often not in the final text. They are in the hidden trajectory: wrong tool, wrong order, missing clarification, or dangerous tool use in the wrong scenario.

What to assert

• tool presence
• tool sequence
• forbidden tool usage
• clarification before action
• output checks only when the wording is stable enough to matter

How EvalView helps

• clusters behavior by tool path instead of treating every phrasing variation as a new test
• generates native YAML tests from live probing or logs
• turns approved behavior into a regression gate in CI/CD
