versioning-apis

Implement API versioning with backward compatibility, deprecation notices, and migration paths. Use when managing API versions and backward compatibility. Trigger with phrases like "version the API", "manage API versions", or "handle API versioning".

Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured skill body: lean overview, concrete stepwise instructions, a genuinely useful error table, and a clean one-level reference bundle. Main improvement levers are inline executable snippets and explicit mid-workflow validation checkpoints.

Suggestions

Add a small copy-paste-ready snippet for the version router or compatibility layer (or point to one in references/implementation.md) to lift actionability.

Convert terminal verification steps into explicit checkpoints, e.g., 'Run the breaking change detector before adding deprecation headers; fix flagged breaks first'.

Trim the Prerequisites list to items that are genuinely required, moving optional context (e.g., gateway choices) into references/implementation.md.

DimensionReasoningScore

Conciseness

The body is efficient — no explanations of concepts Claude already knows, each instruction is one dense actionable sentence, and the error table is compact — but sections like Prerequisites and Resources contain lines that could be trimmed or inferred (e.g., 'Version control history for tracking breaking changes'). It sits above 'mostly efficient with some unnecessary explanation' (3) but short of 'every token earns its place' (5).

4 / 5

Actionability

Guidance is concrete and executable in direction — exact deprecation headers ('Deprecation: true', 'Sunset: <date>', 'Link: <url>; rel="sunset"'), specific output paths, named tools (oasdiff, openapi-diff), and HTTP status semantics — with details deferred to references/implementation.md. It falls short of level 5 because no inline copy-paste-ready code or commands are given, leaving steps like 'Create a version router' at the specific-but-not-executable level.

4 / 5

Workflow Clarity

The 8 numbered steps form a coherent sequence from audit through strategy selection, implementation, and testing, with verification present via the compatibility tests (step 8) and breaking change detector (step 7), plus an Error Handling section for recovery. It is not level 5 because validation appears as terminal steps rather than explicit 'validate before proceeding' checkpoints interleaved through the workflow.

4 / 5

Progressive Disclosure

The SKILL.md is a well-organized overview that defers detail to three clearly signaled, one-level-deep references ([references/implementation.md], [references/errors.md], [references/examples.md]) which all exist as real files and contain no further nesting, matching the anchor for a clear overview with well-signaled single-level references and easy navigation.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description that states concrete capabilities in third person and provides both an explicit 'Use when' clause and natural trigger phrases. Keyword coverage could extend to synonyms like 'deprecate', 'sunset', and 'breaking changes' for even better recall.

Suggestions

Add trigger synonyms such as 'deprecate the API', 'sunset a version', or 'API breaking changes' to broaden natural keyword coverage.

Mention one or two supporting capabilities from the body (e.g., breaking change detection or sunset header management) to close the minor specificity gap.

DimensionReasoningScore

Specificity

Lists several concrete capabilities — 'Implement API versioning with backward compatibility, deprecation notices, and migration paths' — going beyond naming the domain, though it omits supporting actions present in the body (breaking change detection, sunset headers). It fits the 'several specific actions; minor gaps' anchor rather than the comprehensive level-5 coverage, and is well above the 1-2 action level.

4 / 5

Completeness

It clearly answers 'what' ("Implement API versioning with backward compatibility, deprecation notices, and migration paths") and 'when' with an explicit "Use when managing API versions and backward compatibility" clause plus concrete trigger phrases, matching the anchor requiring both what and when with concrete triggers.

5 / 5

Trigger Term Quality

Natural phrases like "version the API", "manage API versions", and "handle API versioning" would plausibly be said by a user needing this skill, but common variants such as 'deprecate the API', 'sunset', 'API migration', or 'breaking changes' are missing, so it falls short of the level-5 comprehensive synonym coverage.

4 / 5

Distinctiveness Conflict Risk

API versioning is a clear niche with distinct, version-specific trigger phrases, minimizing the chance of firing for unrelated skills; it does not fall to level 4 because the stated triggers ('version the API', 'handle API versioning') are not shared by closely related skills.
