🛑 Most Function-Calling Failures Are Not Schema Failures. They Are State Failures.
The model believes the world is still valid — when reality has already changed.
It calls the right tool with stale beliefs, gets "success", and moves on. That is how agents silently corrupt production state.
This dataset trains argument-level correctness under changing state: multi-turn tool use, error recovery, and explicit verification steps — not just happy-path calls.
