In "Andrej Karpathy's Math Proves Agent Skills Will Fail. Here's What to Build Instead.", A concept popularized by Andrej Karpathy describing the exponential difficulty of increasing reliability. In agentic workflows, it explains how failure rates compound across multiple steps, requiring significant engineering…
In "Andrej Karpathy's Math Proves Agent Skills Will Fail. Here's What to Build Instead.", The discipline of wrapping AI models in a software layer (the harness) to provide deterministic rails, validation, and state management. It moves beyond simple prompting to ensure the AI follows a rigid, codified process.
In "Andrej Karpathy's Math Proves Agent Skills Will Fail. Here's What to Build Instead.", The degradation of an LLM's performance and coherence as its context window fills up with too much information. Harnesses solve this by using sub-agents to isolate specific tasks into fresh, lean context windows.
Agentic workflows naturally compound failure, making simple prompting insufficient for high-stakes business tasks. The host reveals how 'harness engineering'—wrapping AI in a software scaffold—enables reliable execution of complex processes like legal audits. This shift from probabilistic hope to deterministic control is what finally unlocks real enterprise value.
