68%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A compact, well-structured skill with genuinely executable code snippets and a useful method-selection table. Its main weakness is the deprecation workflow: phases are listed but no validation or verification steps gate the destructive shutdown steps, capping workflow clarity at 3.
Suggestions
Add validation checkpoints to the deprecation timeline, e.g. "Before Sunset: confirm version-usage metrics for v1 have dropped below threshold; otherwise extend the window" and "Before Shutdown: verify no 4xx spikes in monitoring".
Trim the 'Safe vs Breaking Changes' section to a one-line rule ("bump version only for removals/type changes/restructuring; optional additions are safe") since Claude already knows what constitutes a breaking change.
Include a usage example for the version adapter (mounting both routers and routing v1 clients through v1ToV2) so the pattern is copy-paste ready end to end.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean — comparison table, short Express snippets, and compact timelines with no padding. Not a 5 because "Safe vs Breaking Changes" and "Best Practices" restate knowledge Claude already has (what a breaking change is, "monitor version usage") and could be trimmed. | 4 / 5 |
Actionability | Concrete executable guidance: "app.use('/api/v1', v1Router)", the version adapter transform, and Deprecation/Sunset/Link header middleware, plus a concrete phased timeline. Not a 5 because snippets are not copy-paste-complete (no full Express app context, adapter has no usage example) and common cases are not covered end-to-end; not a 3 because the code is real and executable, not pseudocode. | 4 / 5 |
Workflow Clarity | The deprecation timeline table gives a rough phased sequence ("Deprecated 3 months → Sunset Announced → Read-Only → Shutdown 410 Gone") but contains no validation checkpoints such as verifying version-usage metrics before sunsetting. Deprecation and shutdown are destructive to API consumers, and the rubric caps destructive workflows lacking validation at 3 — this also rules out the simple-skill exception. | 3 / 5 |
Progressive Disclosure | No bundle files exist, and the single self-contained SKILL.md has well-organized sections (no nested references, nothing that should clearly move to a separate file). Not a 5 because at ~77 lines it exceeds the under-50-line simple-skill criterion, and timeline/best-practice material could optionally live in a reference file. | 4 / 5 |
