Evaluate an agent upgrade against its installed version

Why use this

1. An operator considering an agent update may see many merged changes without knowing which are included in the release or relevant to the installed configuration. An attractive feature list can distract from changed defaults or migration requirements.

2. A baseline-specific comparison could separate applicable changes from unrelated development work and identify what needs testing before an upgrade decision. The recommendation would support consideration without implying that an installation has occurred or compatibility is established.

Why an agent / simpler alternative

Useful judgment

Connect release changes with the owner’s used features and identify unresolved compatibility questions.

Simpler alternative

Read release notes directly when the update is small and the installation is standard.

Unsuitable when

The installed baseline or release membership cannot be verified.

Proposed inputs

1. Name

   Installed-version inventory

   Owner

   Operator

   Minimum scope

   Version identifier, relevant configuration and used features without secrets

   Quality check

   Confirm the inventory reflects the actual installation.

2. Name

   Release evidence packet

   Owner

   Maintainer or operator

   Minimum scope

   Tagged release notes and relevant merged-change references

   Quality check

   Distinguish merged work from changes actually shipped in the target release.

Access and setup — proposed or unknown

Proposed minimum

1. Read-only supplied version and release records; no package changes.

Compatibility unknowns

1. Unknown: exact runtime, current installed state, plugin compatibility and migration requirements.

External actions requiring approval

1. Installing the upgrade, modifying configuration or granting additional access.

Expected deliverable and review checks

Proposed artifact

Version-difference brief with relevant changes, unresolved risks and proposed pre-upgrade checks.

Critical checks

1. Every cited change belongs to the target release.

2. Recommendation distinguishes feature relevance from demonstrated installation compatibility.

Missing output evidence

No new workflow run or output inspection was performed for this overlay.

Failure signals and proposed responses

1. Signal

   A merged pull request is absent from the release tag.

   Why it matters

   The comparison could promise a feature the update will not contain.

   Proposed response

   Remove it from shipped changes or label inclusion unresolved.

2. Signal

   A local customization depends on a changed default.

   Why it matters

   A generally suitable update may disrupt this installation.

   Proposed response

   Flag the customization and require a bounded compatibility review before upgrading.

Effort and cost — unknown

Setup work

1. Establish the installed baseline and target release scope.

Ongoing review

1. Review migration questions and any later authorized trial evidence.

Unknowns

1. Unknown: upgrade effort, regression risk and maintenance costs.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

An invented release manifest includes one shipped change and one merged-but-unreleased change; the local feature list uses only the latter.

Acceptance checks

1. The unreleased item cannot justify upgrading.

2. Compatibility remains untested.

Stop conditions

1. A live upgrade or unsupported baseline assumption is required.

Limits

1. Editorial comparison only; the synthetic manifest check is not an upgrade or runtime test.
