Principlev1
Evaluate tool interoperability as a primary selection
Evaluate tool interoperability as a primary selection criterion rather than feature richness alone, as disconnected best-in-class tools require you to be the integration layer.
Why This Is a Principle
Grounds to Working Memory Capacity Limit (working memory limits), Open-Loop Cognitive Cost (Zeigarnik) (unresolved commitments consume memory), and Directed Attention as Depletable Resource (attention is finite). Manual data transfer between tools consumes working memory and attention that should be available for thinking. The principle prescribes prioritizing integration over features.
