Quality

Content

92%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.

An efficient, actionable body for a simple single-purpose skill: concrete commands, an explicit hard-fail contract, and clean deferral to a source-of-truth doc. Only minor tightening is possible in the closing paragraph's repetition of the trigger condition.

DimensionReasoningScore

Conciseness

The ~38-line body is lean: it defers rationale to docs/schemathesis.md ("Não copie essa página") and gives commands without padding. Not 5: the closing paragraph restates the trigger condition already in the frontmatter, and "Uma tarefa que muda a API não está pronta só com o loop de lint" could be trimmed to one clause.

4 / 5

Actionability

Two copy-paste-ready invocations are given ("apm run schemathesis --param spec=<...>" and "python3 -m schemathesis run <caminho-ou-url-do-openapi>") with a clear directive on what to target and an anti-shortcut guard ("Não invente um spec na hora"). Commands cover the common cases for this single-purpose skill.

5 / 5

Workflow Clarity

For a simple single-purpose skill the action is unambiguous: run Schemathesis against the platform's spec before closing the task, with the outcome defined ("Falha dura se a implementação divergir do contrato") and failure guidance (never fabricate a spec to mask divergence). The run itself is the validation checkpoint.

5 / 5

Progressive Disclosure

Short, well-sectioned body under 50 lines with no bundle files needed; the source-of-truth page (docs/schemathesis.md) and complementary layer docs are clearly signaled one level deep at the top. Simple-skill structure is fully appropriate.

Description

82%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 well-formed description with an explicit 'Use when...' trigger clause and a clear single action tied to task completion. Its only weakness is thin capability coverage — it says to run Schemathesis but not what it checks or how results are used.

Suggestions

Add one more concrete capability phrase, e.g. 'Run Schemathesis to fuzz the API against its OpenAPI contract and catch unexpected behavior (5xx, schema violations, header mismatches)'.

Include common synonyms such as 'REST', 'endpoints', or 'Swagger/OpenAPI spec file' in the trigger clause to improve natural-term matching.

DimensionReasoningScore

Specificity

"Run Schemathesis against the spec before calling the task done" names the domain (HTTP API / OpenAPI / contract tests) and exactly one concrete action. Not 4: only a single action is listed, not 'several specific actions'; not 2: the action is concrete and tool-named, not generic.

3 / 5

Completeness

Explicitly answers both: what ("Run Schemathesis against the spec before calling the task done") and when ("Use when the task changes an HTTP API, an OpenAPI spec, or routes covered by contract tests"). Both halves are concrete and explicitly stated.

5 / 5

Trigger Term Quality

"HTTP API", "OpenAPI spec", "routes", and "contract tests" are phrases users would naturally say when changing an API. Not 5: common synonyms/extensions ("REST", "endpoints", "Swagger", "spec file") are absent; not 3: coverage of natural phrasing is good, not merely partial.

4 / 5

Distinctiveness Conflict Risk

Clear niche: contract testing with Schemathesis against an OpenAPI spec, with distinct triggers (spec/route/contract changes). Unlikely to fire for unrelated skills; minimal overlap risk.
