How I made yap fast enough for a local coding agent

The slowest thing in yap was how much I made the model read before it could speak. So I cut the tool surface, trimmed the prompt, and rebuilt compression until a 27B Ollama model could actually drive the agent.

I analyzed 1,000 of my prompts. Here's what I learned about talking to AI.

I read through all 1,020 of my substantive prompts and I'm learning to be a more direct communicator.
