Why 4/10

Spend outran budget; the cost is money for usage, not a destroyed asset.

The score is the sum of these four factors. How each factor is scored · scored 2026-10-29

  1. Instruction given

    Roll out AI coding agents across the engineering org.

  2. Expected behavior

    Costs scale predictably and stay within the planned annual budget.

  3. Actual behavior

    Uber rolled out Claude Code to roughly 5,000 engineers in late 2025; by April 2026 the company had exhausted its entire annual AI-coding-tools budget in about four months, with monthly per-engineer costs ranging from $150 to $2,000.

  4. Damage

    An entire annual AI-tools budget consumed in a third of the year. Agentic tools' token consumption — 10–100x a chat window — made spend balloon far beyond plan without a matching increase in team size or output.

Full write-up

When Uber rolled out Anthropic's Claude Code to roughly 5,000 engineers in late 2025, the cost curve broke the budget: by April 2026 the company had burned through its entire annual AI-coding-tools allocation in about four months, with monthly per-engineer costs spanning $150 to $2,000. The root cause is structural to agentic coding tools — each task becomes a long sequence of model calls, and the growing conversation is resent on every call, so token consumption runs 10–100x higher than a chat interface. Teams across the industry reported tripling bills quarter over quarter with no matching growth in headcount, codebase, or delivery. Gartner has projected AI coding costs could eventually rival developer salaries. It is the enterprise-scale version of the runaway-cost failure mode: not one dramatic loop, but sustained, structurally-underestimated spend.

Get told when an agent breaks something

We document AI agent failures daily, severity-scored against a published scale. Each Monday, if any scored 7 or above that week — deleted data, leaked secrets, broken production — you get one email with the sources. When nothing did, you get nothing.
