Coding agent's token use spikes after output cap, experiment finds

By PulseAugur Editorial · [1 sources] ·

An experiment revealed that capping an AI coding agent's tool output at 12,000 characters led to a 2.65x increase in token usage and 2.57x more turns. This occurred because the model, receiving incomplete information, requested the missing data in subsequent turns, ultimately increasing overall token consumption. Further modifications to the agent's tool wrapper, such as pre-summarizing repository structures and consolidating tool outputs, significantly reduced the number of turns and total tokens required for complex queries.

    I capped my coding agent's tool output to save tokens. It used 2.65 times as many.

    <p>To save tokens, I capped every response from my coding agent's code-graph tool at 12,000 characters. One answer then took 18 turns instead of 7, and the input tokens it was billed for went from 267k to 708k, 2.65 times as many.</p> <p>This post explains why a smaller response …
