The Decisive Crux

Current evidence supports Skills for flexibility but lacks control validation.

Cheapest Test

Conduct controlled environment tests to evaluate both Skills and MCP.

Sensitivity: If belief in Skills' flexibility increases, the decision leans towards Skills.
Test Cost: low

The Dissent

"Skills may not provide the predictability needed for mission-critical tasks, favoring MCP."
