Quality

Content

77%Weight 40%Scale 1-3

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

A highly actionable, well-sequenced skill with executable code and a verification checklist. The main weaknesses are repeated boilerplate across examples and the absence of progressive disclosure for a skill this size.

Suggestions

Factor the three full examples and the Anti-Patterns into a separate references/ file (e.g. EXAMPLES.md), keeping SKILL.md as an overview with one-level-deep links.

De-duplicate the import/theme preamble across examples — show the shared header once and reference it, or trim the boilerplate from later examples.

Move the container-sizing and interactive-handler tables into the referenced examples file to reduce inline length while retaining the core decision rules.

DimensionReasoningScore

Conciseness

Largely project-specific and dense, but the full import/theme boilerplate is repeated across three example blocks and the Anti-Patterns section restates guidance already covered in the steps, so it could be tightened.

2 / 3

Actionability

Provides fully executable TSX, exact import paths with the correct eslint-disable comments, decision tables, and concrete file-naming rules — copy-paste ready.

3 / 3

Workflow Clarity

A clear five-step sequence (locate, import path, classify props, write file, order) closes with a 'Checklist: Before finishing' verification block that serves as an explicit checkpoint.

3 / 3

Progressive Disclosure

No bundle files exist and the ~350-line skill keeps everything inline; the substantial Examples and Anti-Patterns sections could be split into referenced files rather than residing in SKILL.md.

Description

90%Weight 40%Scale 1-3

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 with explicit what-and-when structure and excellent natural-language trigger coverage. The only soft spot is specificity, which names a single action rather than enumerating several distinct capabilities.

Suggestions

Broaden the action list beyond 'generate' to surface the distinct sub-actions the skill performs, e.g. 'Generate snapshot test files, classify props into variants, and colocate light/dark theme snapshots for Sentry React components.'

DimensionReasoningScore

Specificity

Names the domain ("Sentry frontend React components") and one concrete action ("Generate snapshot test files"), but does not list multiple distinct actions as the score-3 anchor requires.

2 / 3

Completeness

Explicitly answers both what ("Generate snapshot test files for Sentry frontend React components") and when via an explicit "Use when asked to..." trigger clause.

3 / 3

Trigger Term Quality

Provides six natural phrasings a user would actually say ("generate snapshot tests", "add snapshot tests", "create visual snapshots", "write snapshot tests", "add visual regression tests", "snapshot this component"), giving good coverage.

3 / 3

Distinctiveness Conflict Risk

Targets a clear niche (Sentry React component snapshot tests) with distinct, specific triggers unlikely to fire for unrelated skills.
