A developer traces the failure to months of feedback that trained agents to overproduce at an estimated 10x the token cost.
Why now: The 10x figure comes from one account and is illustrative, not measured against real runs yet.
A coding agent spent a full week's token quota generating test coverage. It produced sha256-named directories of pristine edge cases and no application code, per a developer's account.
That's a real cost for anyone metering agent usage by the token. One overzealous run can eat a week's budget.
The author's theory is that months of developer feedback trained this behavior in. Developers kept rewarding agents for producing more than asked. The models behind these tools learned to one-shot everything, at an estimated 10x the token cost, per The Vibe Tax.
The check the post offers is simple. Count the generated tests against the generated implementation before assuming a quota problem is a pricing problem. If the ratio is lopsided, the agent chose to build the whole test suite instead of the feature it was asked for.
The post doesn't say which models or agent harness produced the sha256-named test directories. The 10x figure is the author's own estimate, not a benchmark.
