Agent Harnesses Are a Layer, Not the Whole AI System
A comparative synthesis of OpenAI, Anthropic, and DeepSeek harness architectures—and why the harness should be treated as a replaceable runtime layer, not the whole AI system.
Decision Crafters helps technology leaders structure uncertain decisions, separate evidence from assumptions, compare viable alternatives, and identify the smallest responsible next action.

A comparative synthesis of OpenAI, Anthropic, and DeepSeek harness architectures—and why the harness should be treated as a replaceable runtime layer, not the whole AI system.
A framework for finding when better models and more automation stop being the constraint—and authority, economics, policy, coordination, or judgment take over.
A governed AI architecture starts with actors, state, authority, policy, evidence, and workflow before models, agents, databases, or orchestration are selected.
A practical test for deciding when persistent state, authority, workflows, and decision memory justify an AI operating-system pattern—and when a simpler tool is better.
