Draft a monitoring plan for an approved code change

Why use this

1. An engineer may approve a code change yet still need to decide what production behavior would reveal a bad release. A generic monitoring checklist can miss the specific failure modes introduced by a changed payment path or dependency.

2. This job could connect the proposed observation plan to the actual change and its risk boundaries. Explicit signals, owners and unresolved instrumentation questions help release reviewers decide what evidence they would need after deployment without implying the release is already safe.

Why an agent / simpler alternative

Useful judgment

Translate code-change scope into observable hypotheses, identify blind spots and separate monitoring from remediation authority.

Simpler alternative

Use an established release checklist when the change does not alter meaningful behavior or dependencies.

Unsuitable when

The plan would authorize deployment, expose sensitive transaction data or automate rollback without permission.

Proposed inputs

1. Name

   Approved change summary

   Owner

   Maintainer

   Minimum scope

   Relevant diff, intended behavior and known risks

   Quality check

   Exclude secrets and confirm exact version

2. Name

   Observability context

   Owner

   Operations owner

   Minimum scope

   Existing aggregate metrics, logs and alert ownership

   Quality check

   Identify privacy limits and unavailable signals

Access and setup — proposed or unknown

Proposed minimum

1. Review a fictional change and monitoring inventory; no production access, query execution, alert changes or deployment.

Compatibility unknowns

1. Current telemetry coverage, signal latency, alert tooling and runtime compatibility are unknown.

External actions requiring approval

1. New instrumentation, production access, alerts, deployment and remediation require explicit approved scope.

Expected deliverable and review checks

Proposed artifact

Change-specific monitoring plan with hypotheses, signal definitions, baseline needs and owner-review questions.

Critical checks

1. Trace signals to changed behavior; distinguish missing telemetry from healthy state; keep rollback/remediation decisions separately authorized.

Missing output evidence

This overlay adds no new output inspection, execution or validation; consult the referenced canonical source outcome limits.

Failure signals and proposed responses

1. Signal

   A key failure has no observable signal

   Why it matters

   A green dashboard may hide the issue

   Proposed response

   Flag the instrumentation gap before release review.

2. Signal

   A metric includes unrelated traffic

   Why it matters

   The plan may miss a scoped regression

   Proposed response

   Define the relevant population and comparison window.

Effort and cost — unknown

Setup work

1. Map change risks to existing observation capabilities.

Ongoing review

1. Engineers review plan adequacy and later authorized production evidence.

Unknowns

1. Signal quality, baseline sufficiency, operational effort and monitoring costs are unknown.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

Invent a payment-retry change and three metric descriptions, one lacking deduplication visibility; draft a monitoring plan.

Acceptance checks

1. Flag blind spots; protect transaction data; claim no release validation; change no alerts.

Stop conditions

1. Stop if the plan requires unapproved sensitive telemetry or deployment authority.

Limits

1. A monitoring plan cannot establish release safety, detect every failure or authorize production intervention.
