the best outcome this tool aims for every other number is worse

"Makes your AI agent think like the laziest senior dev in the room. The best code is the code you never wrote." Laziest is the operative word, and it is doing something specific: pointing the agent at deletion and refusal rather than output volume.

What every other agent optimises

Generation is the easy metric and the one that demos well. An agent that writes more looks more capable in a screenshot and costs more to maintain afterwards.

What this one optimises

Lines avoided

"the laziest senior dev in the room"

Seniority here means knowing which request does not need code. The description picks a person rather than a technique, which is a sharper way to specify a behaviour.

Concept mock, not affiliated with the project. Both quoted phrases come from the repository's own GitHub Trending description on 27 August 2026: "Makes your AI agent think like the laziest senior dev in the room. The best code is the code you never wrote." No benchmark, diff size, token figure, or acceptance rate is represented here, because that description publishes none.
