Quality

Content

92%

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 executable examples and a verification checklist, but it is a monolithic single file with no progressive disclosure structure splitting detailed examples into separate references.

Suggestions

Consider moving the longer worked examples (e.g., contract testing, integration with test containers) into referenced files under ./references/ and keeping SKILL.md as a concise overview with one-line links, to improve progressive disclosure.

DimensionReasoningScore

Conciseness

The body is lean: each section is a tight executable example followed by a single one-line takeaway, with no padding explaining what testing is or how the libraries work, so every token earns its place.

3 / 3

Actionability

Every section provides complete, copy-paste-ready TypeScript with real imports and APIs (Pact, fast-check, testcontainers, hand-rolled test doubles), matching the anchor for fully executable, specific examples.

3 / 3

Workflow Clarity

This is a patterns/catalog skill rather than a multi-step destructive process; per the simple-skills note, clarity can score 3 when content is unambiguous, and the closing checklist supplies an ordered set of verification criteria.

3 / 3

Progressive Disclosure

No bundle files exist and the skill is a single ~195-line file with no external references; it is well-organized by headers but the detail (longer code examples) is inline in one monolithic file rather than split into one-level-deep references, matching the 'content that should be separate is inline' anchor.

Description

75%

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 uses natural trigger terms, but it omits any explicit when-to-use guidance, which caps completeness and leaves it slightly generic against other testing skills.

Suggestions

Add a 'Use when...' clause naming the situations or user phrasings that should trigger this skill (e.g., 'Use when setting up contract, snapshot, mutation, or property-based tests, or organizing a test suite').

Differentiate from a general testing skill by framing around advanced/non-obvious strategies rather than the generic 'testing strategies' framing.

DimensionReasoningScore

Specificity

The description enumerates multiple concrete strategies — 'contract testing, snapshot testing, mutation testing, property-based testing, and test organization' — matching the anchor for listing multiple specific concrete items rather than naming only a domain and some actions.

3 / 3

Completeness

It clearly answers 'what' (the listed strategies) but provides no 'Use when...' clause or equivalent trigger guidance, so per the judging guidelines completeness is capped at 2 — when-to-use is missing rather than explicit.

2 / 3

Trigger Term Quality

Terms like 'contract testing', 'snapshot testing', 'mutation testing', and 'property-based testing' are the natural vocabulary a developer would say when reaching for this skill, giving good coverage of relevant trigger terms.

3 / 3

Distinctiveness Conflict Risk

The named sub-techniques give it a recognizable niche, yet 'testing strategies' is broad enough to overlap with a general testing or test-writing skill, matching the anchor for being somewhat specific but still potentially overlapping.
