Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a well-crafted skill description that clearly articulates specific capabilities (API versioning via multiple methods), includes natural trigger terms developers would use, and explicitly states both what it does and when to use it. The description is concise, uses third-person voice correctly, and occupies a distinct niche that minimizes conflict with other skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: implementing API versioning via URL paths, headers, or query parameters, with backward compatibility and deprecation strategies. These are concrete, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both what ('Implements API versioning using URL paths, headers, or query parameters with backward compatibility and deprecation strategies') and when ('Use when managing multiple API versions, planning breaking changes, or designing migration paths') with explicit trigger guidance. | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'API versioning', 'URL paths', 'headers', 'query parameters', 'backward compatibility', 'deprecation', 'breaking changes', 'migration paths', 'multiple API versions'. Good coverage of terms a developer would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly specific niche around API versioning strategies. Unlikely to conflict with general API design skills due to the focused scope on versioning, deprecation, and migration paths specifically. | 3 / 3 |

Implementation
37%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The skill provides a decent overview of API versioning approaches with useful code snippets and reference tables, but lacks a coherent workflow tying the pieces together. The content reads more like a reference card than an actionable guide—Claude would know most of the conceptual content (safe vs breaking changes, pros/cons of versioning methods) and would benefit more from a step-by-step implementation workflow with validation checkpoints. The hardcoded sunset date in the deprecation header example is a time-sensitive detail that will become stale.
Suggestions
Add a clear step-by-step workflow (e.g., 1. Choose versioning method → 2. Set up routing → 3. Implement adapters → 4. Add deprecation headers → 5. Verify backward compatibility with tests) with explicit validation checkpoints.
Remove the 'Safe vs Breaking Changes' section as this is knowledge Claude already has, and trim the pros/cons table to save tokens.
Replace the hardcoded sunset date ('Sat, 01 Jun 2025 00:00:00 GMT') with a placeholder or computed value to avoid time-sensitive staleness.
Make code examples more complete and executable—e.g., include the Express app initialization and show how to wire up the full versioning setup end-to-end.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient with good use of tables and code examples, but includes some unnecessary explanation like the pros/cons table and the safe vs breaking changes section which Claude already knows. The deprecation timeline with specific durations is somewhat opinionated guidance that earns its place, but the best practices bullet points are generic. | 2 / 3 |
Actionability | Provides concrete code snippets for routing, version adapters, and deprecation headers, but the examples are incomplete fragments rather than fully executable solutions. The routing example lacks the Express app setup, and the adapter pattern is a standalone function without integration context. | 2 / 3 |
Workflow Clarity | There is no clear sequenced workflow for implementing versioning. The content presents isolated concepts (methods, adapters, headers, deprecation) without connecting them into a coherent process. There are no validation steps or checkpoints for verifying that versioning is correctly implemented or that backward compatibility is maintained. | 1 / 3 |
Progressive Disclosure | Content is reasonably structured with clear section headers and good use of tables, but everything is inline in a single file. The deprecation timeline, version adapter patterns, and migration strategies could benefit from being split into referenced files, especially given the breadth of topics covered. | 2 / 3 |
