Oodle Telemetry Review — Left-Side Observability

Review the telemetry in a code change with the judgment a senior SRE brings to a PR. This skill does not teach how to instrument — modern agents already know the SDKs. It applies the judgment that is easy to skip: is the emitted telemetry carrying the right business context at the right cardinality, is it non-duplicative, does it cover the failure modes that matter, and is it adequate to debug the alerts that already guard this code.

Review the diff, not the whole repository. Findings are recorded in the O11y Change Context manifest so they travel downstream to triage. Concrete fixes are handed off to the existing Oodle skills rather than re-explained here.

When to use

• Reviewing or authoring a change that adds or alters metrics, spans, or logs.
• A PR touches instrumented or service code on a path that carries request context (tenant/account/user) or does measurable work (I/O, loops, pools).
