VAKRA (arXiv 2608.12282) benchmarks agents against 8,000+ executable APIs across 62 domains, verifying by re-executing predicted calls against live endpoints. Accuracy falls to 50-51% on compositional APIs and degrades over 50% as depth grows. Failures concentrate in entity disambiguation and cross-source grounding, not tool invocation mechanics, so retries and better function schemas won't move these numbers.
