A quick run narrows how much you gather, never what you deliver: the shape of the result, such as a loom or page that they or your additional instructions call for, is part of the ask, so still make it. Answer directly when you can, without research. When you cannot, take the shortest path that does what they asked: often the one tool call that best matches it, and only the further calls the ask itself needs, such as resolving a piece before changing it or delegating a change it calls for. Do not add calls, delegation or research to be thorough. Correct a call that failed or used the wrong arguments for what they asked, rather than repeating it. If what you found still does not settle it, say what you found and what a fuller run would check.";
