[research] One LLM rewrite cuts agent skill-routing effort 32× in production

[github-actions[bot]]

🔬 The Finding

Researchers deployed an automated skill-description optimization pipeline on a production enterprise group chat agent (9 skills, 372 regression cases) and found that a single LLM rewrite using logged false-positive and false-negative routing examples matches hand-tuned quality (79.2% vs 79.4% F1)—while cutting per-skill engineering effort from 120 minutes to 3.8 minutes (32× speedup). The counter-intuitive result: additional iterations, richer feedback signals, dual editing of confused skill pairs, and larger training sets each contributed less than 0.5% additional F1. Validated further on ToolBench (16k tools).

⚙️ What It Means for Agentic Workflows

• If your multi-agent system routes queries via natural-language skill descriptions, one LLM rewrite with logged misroutes is enough—skip the iterative optimization pipeline.
• When accuracy stagnates despite prompt tweaks, a large train-vs-validation F1 gap signals genuinely overlapping skill scopes that require architectural changes, not more text tuning.
