𝗧𝗵𝗲 𝟰 𝗟𝗮𝘆𝗲𝗿𝘀 𝗼𝗳 𝗮𝗻 𝗔𝗴𝗲𝗻𝘁 𝗦𝘆𝘀𝘁𝗲𝗺 An agent can burn tokens, declare success, and still fail the tests. That’s often an architecture problem, not a prompting problem. 𝟭. 𝗟𝗼𝗼𝗽 → Decides whether to continue Acts → verifies → retries until there’s evidence of success. 𝟮. 𝗚𝗿𝗮𝗽𝗵 → Decides what runs next Handles branches, retries, handoffs, fallbacks, and shared state. 𝟯. 𝗛𝗮𝗿𝗻𝗲𝘀𝘀 → Gives the model its capabilities Tools, APIs, files, memory, permissions, context, and execution environment. 𝟰. 𝗠𝗲𝘁𝗮-𝗛𝗮𝗿𝗻𝗲𝘀𝘀 → Governs multiple agent environments Coordinates different agents, tools, policies, permissions, and workflows. 𝗧𝗵𝗲 𝗺𝗲𝗻𝘁𝗮𝗹 𝗺𝗼𝗱𝗲𝗹: Loop = verification Graph = workflow Harness = capability Meta-harness = governance A better model can improve reasoning. But reliable agents depend on the architecture built around the model.
