The original post
I have to admit that I’ve, at least, duplicated my token usage efficiency by implementing a tool-check plugin I created with Jev @typesafeai for Claude. I’ll make it public very soon, running the final tests in real scenarios.
Engagement when collected
Numbers are a snapshot taken from X when the case was added to the library (schema v1, collected 2026-09-19); they will not match today.
Where this case fits
Filed under coding & developer tools. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the coding & developer tools page.
