Apple researchers have developed a "Reinforced Agent" that proactively verifies tool calls before execution, aiming to prevent errors rather than correcting them post-hoc. This approach demonstrated significant improvements on benchmarks like BFCL irrelevance and τ²-Bench, with reasoning-model reviewers achieving a 3:1 helpful-to-harmful ratio. The system also saw a modest gain with the GEPA prompt optimization without requiring model retraining. AI
