Prompt and Skill Update

When many trajectories reveal one strategic mistake, expressible in words, — elevate it from “recommended experience” to “mandatory rule”. System prompt learning (Carpathian term): model without a notebook — like the hero of “Memento”. Change — minimal diff based on a cluster of homogeneous failures, specifying scope and conflict checking; evaluate on edge cases and the old set. For Skill: first look for a close ability in the library (local patch instead of a new directory); candidate Skill describes when to load, preconditions, steps, pitfalls, how to verify. DSPy, OPRO, GEPA — automated offline optimization; production — constant minimal edits.
