We Deleted Two Tools and a Wizard. Every Turn Got 4% Lighter.
Every request a coding agent sends carries the same baggage: the system prompt and the definition of every tool the model may call. It is cached, so it is cheap to resend, but it still fills the context window and still counts. For Atlarix 15.11 we went looking for what nobody used and deleted it. The result is small, and that is the point of this post: it is about 4% of every turn, forever. What…
Atlarix 15.11 removed two mobile tools and a wizard to improve efficiency, cutting 4.2% from every request. The mobile tools for phone emulators were seldom used and could be replaced by person typing commands, so they were eliminated. Image tools were kept for models that could process images but removed for text-only models. The first-run wizard, onboarding, and other features were also removed to save space and improve performance.
Measuring the impact, Atlarix found 452 tokens and two fewer tools per request, resulting in a 4.2% reduction. This decrease, though small, becomes significant when multiplied across many model calls, especially for weaker models. Atlarix's rule is simple: features stay if used or needed by the model; otherwise, they go. The change was implemented in Atlarix 15.11, streamlining the experience and focusing on what truly matters.
