The Regression Tax: Decomposing Why Skills Help and Hurt LLM Agents
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- Research shows adding skills to LLM agents often causes regressions where previously solved tasks now fail, offsetting gains from new capabilities.
- Why it matters
- Matters for engineers building agentic systems who need to understand that skill improvements must be evaluated by net effect, not average gains alone.
- Watch out
- Study focuses on office automation benchmarks; findings may not generalize to all agent domains or task types beyond those tested.
