AI coding agent costs driven by steps, not tokens, study finds

By PulseAugur Editorial · [1 sources] ·

An investigation into the cost of AI coding agents revealed that the number of steps an agent takes, rather than token usage, is the primary driver of expense. The author built an open-source tool called `knock` to optimize these agents. Initial versions of `knock` failed to reduce costs, but a later version that provided the agent with a map of the codebase significantly cut down on unnecessary exploration and tool calls, leading to substantial savings on large, unfamiliar codebases. AI

IMPACT Optimizing AI coding agents by reducing steps could significantly lower operational costs for developers and enterprises.

RANK_REASON The item describes the development and testing of a new tool (`knock`) designed to optimize AI coding agents.

    I recorded 87 Claude Code sessions to find out where the money goes

    <p>I wanted to know why AI coding agents get expensive on real codebases, so I stopped guessing and started recording. Every session in this post is a real Claude Code run (Claude Sonnet 5), saved as a full transcript with the cost Claude Code reported. 87 sessions in total, on t…
