Approve the logic once, then let it run the same way forever.

TL;DR: Turn repeatable skill steps into tested scripts instead of prompts, so behavior stays deterministic and cheap.

Common Mistake ❌

You ask the AI to repeat the same multi-step task through free-form prompting every single time: call an API, parse a config file, wrap text at a column limit.

Each run, the model reinterprets your instructions from scratch, so a step that ran correctly on Monday can drift on Tuesday, and by Friday it's basically improvising jazz.
