Quality

Content

87%

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, highly actionable, and well-organized, with the only gap being workflow clarity: the test/debug sequences lack explicit validation checkpoints and feedback loops despite the skill covering destructive operations.

Suggestions

Add an explicit validate->fix->retry loop for destructive or batch operations (e.g., after sending a DELETE, confirm the resource is gone with a follow-up GET before proceeding).

Insert verification checkpoints into the Testing Methodology, such as asserting the expected status code and response schema before moving to the next test category.

Add a brief post-test verification step that re-requests a modified resource to confirm the persisted state matches expectations.

DimensionReasoningScore

Conciseness

The body is lean and bullet-driven with concrete commands and almost no filler, assuming Claude's competence; it does not lecture on HTTP fundamentals and every section earns its place, matching the level-3 anchor.

3 / 3

Actionability

It provides fully executable, copy-paste-ready curl commands, an explicit GraphQL introspection query, and concrete test cases with expected status codes, matching the level-3 'executable code/commands, copy-paste ready' anchor.

3 / 3

Workflow Clarity

The Testing Methodology and Debugging sections give a clear sequence, but there are no explicit validation checkpoints or fix-and-retry feedback loops, and the body itself flags destructive operations (DELETE, bulk updates) without embedding a concrete validation step, which caps this at 2.

2 / 3

Progressive Disclosure

The skill is under 50 lines, single-file, has no bundle files and no broken reference links, and is organized into clear headed sections, satisfying the rubric note that such skills can score 3 on well-organized sections alone.

Description

50%

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 communicates the skill's niche and tooling clearly but is missing an explicit 'when to use' trigger and broader natural keyword coverage, leaving every dimension at the middle anchor.

Suggestions

Add an explicit 'Use when ...' clause naming natural user phrases such as testing REST/GraphQL endpoints, debugging HTTP requests, or working with curl/Postman.

Expand the capability list beyond tool names to concrete actions (e.g., 'send authenticated requests, validate status codes and response bodies, debug failed calls').

Broaden trigger terms with common variations like 'endpoints', 'HTTP requests', and 'Postman' that users are likely to say.

DimensionReasoningScore

Specificity

Names the domain (API testing) plus concrete tools/areas (curl, REST, GraphQL, authentication, debugging), but describes domains rather than enumerating multiple specific concrete actions, matching the level-2 anchor rather than the multi-action level-3 example.

2 / 3

Completeness

It clearly states what the skill does (API testing for those tools/areas) but has no 'Use when...' clause or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 2.

2 / 3

Trigger Term Quality

Includes several natural terms users would say (REST, GraphQL, curl, authentication, debugging), but is tool-name oriented and misses common variations like 'endpoints', 'HTTP requests', or 'Postman' that the body itself uses, so it stops at 'some relevant keywords but missing common variations'.

2 / 3

Distinctiveness Conflict Risk

The curl/REST/GraphQL framing gives it a reasonably distinct niche, but it could still overlap with general HTTP/web or debugging skills and lacks the explicit-trigger distinctiveness shown in the level-3 example.
