Beyond the Prompt: Why "Harness Engineering" is...

If you’ve spent any time building with LLMs lately, you’ve likely hit the "ceiling of fragility." You craft the perfect prompt, and it works 80% of the time. But in production, that 20% failure rate is a nightmare. Most people try to solve this with Prompt Engineering (words) or Context Engineering (data). But the frontier—led by teams at OpenAI and companies like Harness.io—is moving toward Harness Engineering. The Technical Hierarchy: Prompt vs. Context vs. Harness To understand why this works
