Your Agent Is Failing Because You’re Solving the Wrong Problem: Stop Tuning Prompts, Start Managing Context
Stop treating prompt engineering as the silver bullet for agent instability. The real leverage is context engineering: controlling what information enters the model’s window at each step — retrieval, compression, memory, and isolation. Most failures come not from bad prompts, but from conflicting, outdated, or irrelevant context. The most mature agents don’t accept more data; they ruthlessly exclude what’s not needed.
