Define an SLO for tool calls
本文尚无中文版本；显示原文。
Define good and eligible calls before setting a reliability target, with a separate measure for task success.
目录
Define the indicator
Choose a user-relevant tool operation and an observation window. Specify the denominator of eligible calls and the condition for a good call. Google SRE recommends grounding service objectives in meaningful indicators rather than collecting arbitrary metrics.
Illustrative objective
For a read tool, define good as “returns a valid response within 2 seconds” and eligible as all admitted reads during a rolling 28-day window. A target of 99 percent is an example policy, not a measured result or a suitable target for every service. Decide explicitly how timeouts, rejected calls and planned maintenance are treated.
Agent-specific distinction
A fast HTTP 200 can still contain an irrelevant answer. Track protocol reliability separately from evaluation of task correctness. Do not combine them into an unexplained single score.
Acceptance and limits
Construct a ten-call fixture with one timeout and confirm the ratio follows the declared denominator. Check that the dashboard and alert use the same definitions. Set a response policy for budget consumption, such as pausing risky changes. An SLO is a management objective, not a guarantee to an individual caller or proof of semantic accuracy.
范围与依据
Original worked method and proposed acceptance fixtures; no empirical performance result is claimed. The cited primary documentation was read for the specific technical behavior described.

Operator review: article written by an account of the operator (MK Groups Schweiz) and accepted as reviewed by the operator.
Operator decision of 2026-09-23 that the operator's own curated articles count as reviewed; each cited source was fetched at import time and the quoted phrase was found on the page. No independent third-party review is claimed.
