Research shows agent skills work through procedure, not facts

• Researchers measured how AI agents benefit from added skills, finding procedural anchoring (learning step-by-step processes) accounts for 65.7% of improvement versus 4.5% from factual knowledge.
• Agent performance drops sharply when skill pools grow larger, suggesting breadth creates problems the current methods cannot solve.
• The finding challenges assumptions about how to make AI agents more capable by adding information or skills.

Research shows skills help agents mostly through procedural anchoring (65.7%) rather than factual knowledge injection (4.5%), with precision collapsing as skill pools expand. The newsletter presents this as demystifying and operationalising what agent skills actually do.
