Realistic before/after scenarios for each /platform-skills:pr-review mode. Each example shows the input that triggers a finding and the expected output the command produces.

Quick Start

Get the diff for a real PR and pipe it in:

gh pr diff 42 | pbcopy    # macOS

Then in Claude:

/platform-skills:pr-review cost
[paste diff]

Or run all modes at once:

/platform-skills:pr-review full 42

Example by Mode

cost

/platform-skills:pr-review cost

[paste examples/pr-review/cost/deployment-replica-increase.yaml diff]

Expected findings:

[COST] HIGH — replica increase with estimated $/month delta
[COST] MEDIUM — missing resource requests on containers

drift

/platform-skills:pr-review drift

values-dev.yaml: [paste]
values-prod.yaml: [paste]

Expected findings:

[DRIFT] HIGH — ssl-redirect annotation missing in prod
[DRIFT] MEDIUM — featureFlags.newCheckoutFlow absent in prod
[DRIFT] MEDIUM — resources.requests missing in prod

ownership

/platform-skills:pr-review ownership

[paste diff adding platform/ directory]

Expected findings:

[OWNERSHIP] HIGH — no CODEOWNERS entry for new path
[OWNERSHIP] MEDIUM — new Terraform module with no README
[OWNERSHIP] MEDIUM — Namespace with no team label

compliance

/platform-skills:pr-review compliance

[paste examples/pr-review/compliance/iam-wildcard.tf diff]

Expected findings:

[COMPLIANCE] CC6.1 CRITICAL — wildcard IAM action and resource
[COMPLIANCE] CC6.7 CRITICAL — RDS storage_encrypted = false

upgrade

/platform-skills:pr-review upgrade

[paste examples/pr-review/upgrade/deprecated-apis.yaml diff]

Expected findings:

[UPGRADE] BREAKING — networking.k8s.io/v1beta1 removed in 1.22
[UPGRADE] BREAKING — batch/v1beta1 removed in 1.25

rollback

/platform-skills:pr-review rollback

[paste examples/pr-review/rollback/rds-storage-increase.tf diff]

Expected findings:

[ROLLBACK] Reversibility: NONE, Blast radius: DATA — RDS storage increase
[ROLLBACK] Reversibility: MANUAL — prevent_destroy removal
Rollback Risk Score: 🔴 HIGH

Produces all six sections in sequence, ending with a Merge Readiness Summary:

Cost delta:      +$280/month (2 findings)
Drift:           3 environment mismatches
Ownership gaps:  2 findings
Compliance:      2 control areas affected (2 critical)
Upgrade risk:    2 deprecated items (2 breaking)
Rollback score:  🔴 HIGH

Blockers (must fix before merge):
  - Wildcard IAM (CC6.1)
  - Unencrypted RDS (CC6.7)
  - RDS storage increase: take snapshot first
  - networking.k8s.io/v1beta1 Ingress (removed in 1.22)
