Your AI writes too much code. Make it write less.
LeanToken is a free plugin for AI coding agents. Before your agent writes anything, it checks for a simpler way: code you already have, something built in, or no change at all. Then it measures what that actually saves.
Real code written by Claude in the LeanToken benchmark. Each side shows a typical run, and hidden tests check every result.
What happened when we measured it
What makes it work?
We tried a shorter checklist, the full one without its example APIs, and the full one with each step removed in turn. Each bar is the change against an agent with no checklist. Bars to the left mean less. Step-removal rows ran each task once, so they are noisier.
