Quality

Content

65%

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

The body is concise and well-organized with a useful content map, checklist, and anti-patterns, but it references per-topic files and an overview that do not exist in the bundle and lacks explicit validation checkpoints in its workflow.

Suggestions

Add the referenced reference files (api-style.md, rest.md, response.md, etc.) to ./references/, or remove the content-map rows that have no backing file.

Add an explicit validation/feedback loop to the decision workflow — e.g. run `python scripts/api_validator.py` and iterate until critical issues resolve before proceeding.

Tighten the script table and 'When to Use'/'Limitations' sections, which currently read as generic boilerplate rather than API-specific guidance.

DimensionReasoningScore

Conciseness

The body is lean and table-driven, assuming Claude's competence — it avoids explaining what REST or GraphQL are and lets every section earn its place via a content map, checklist, and anti-patterns.

3 / 3

Actionability

It points to a real executable script (`python scripts/api_validator.py <project_path>`) and gives concrete DO/DON'T rules, but the core design guidance lives in referenced files that are not present, so on-the-page instruction is incomplete.

2 / 3

Workflow Clarity

The decision checklist sequences pre-design steps, but there are no explicit validation checkpoints or feedback loops (validate -> fix -> retry) for the destructive/batch operations the validator script targets.

2 / 3

Progressive Disclosure

A clear content map signals one-level-deep references to per-topic files, but none of the listed reference .md files actually exist in the bundle, so the promised progressive structure is not realized.

Description

67%

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

The description is specific and distinctive, naming several concrete API-design sub-tasks, but it lacks an explicit 'Use when...' trigger clause and misses some natural user phrasings, capping completeness and trigger-term quality at 2.

Suggestions

Add an explicit trigger clause, e.g. 'Use when designing or reviewing an API, choosing between REST/GraphQL/tRPC, or planning response formats, versioning, or pagination.'

Include natural user-facing terms such as 'API design', 'endpoint design', or 'building an API' alongside the protocol names to improve trigger-term coverage.

Use third-person action verbs consistently (e.g. 'Guides API design decisions...') to match the rubric's voice guidance.

DimensionReasoningScore

Specificity

The description lists multiple concrete capabilities ('REST vs GraphQL vs tRPC selection, response formats, versioning, pagination'), naming distinct sub-tasks rather than vague abstractions.

3 / 3

Completeness

It clearly answers 'what' (design principles and decision-making across listed concerns) but lacks an explicit 'Use when...' trigger clause, so the 'when' is only implied — capping completeness at 2 per the rubric.

2 / 3

Trigger Term Quality

It surfaces recognizable terms ('REST', 'GraphQL', 'tRPC', 'versioning', 'pagination'), but omits common user phrasings like 'API design', 'endpoint design', or 'building an API' that a user would naturally say.

2 / 3

Distinctiveness Conflict Risk

The focused API-design niche with specific style-selection triggers (REST/GraphQL/tRPC) is clearly distinguishable from adjacent skills and unlikely to fire for the wrong skill.
