Principlev1
Treat every tool as a component of your extended cognitive
Treat every tool as a component of your extended cognitive system rather than as an external convenience, selecting and configuring tools based on architectural criteria of reliability, maintainability, interoperability, and failure-mode transparency.
Why This Is a Principle
Derives from Extended Cognition Thesis (cognition distributed across external artifacts as genuine parts of cognition), Structural Correspondence in Mental Models (mental models have structural correspondence to reality), and The performance of an agent is bounded by the accuracy of (agent performance bounded by world model accuracy). The principle prescribes treating tool selection as cognitive architecture design because tools are cognitively constitutive, not merely assistive.
