Quality

Content

50%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.

The body is well-sectioned with mostly concrete, executable code examples, but the bulk of it restates basic programming knowledge Claude already has, and everything is packed into a single large file with no progressive disclosure. The vacuous 'When to Use' section adds no operational guidance.

Suggestions

Cut the sections that restate universal knowledge (KISS/DRY/YAGNI, early returns, magic numbers, Promise.all, AAA pattern) and keep only project-specific or non-obvious conventions, cutting the body well under 150 lines.

Move domain-specific detail (React patterns, API design, testing standards, code smells) into clearly signaled one-level-deep reference files (e.g., references/react.md, references/api-design.md) linked from a concise overview.

Replace the filler 'When to Use' section with concrete application guidance, such as a review checklist to run against changed code or a decision flow for which standard applies when writing new code.

DimensionReasoningScore

Conciseness

The 525-line body re-explains concepts Claude already knows — KISS, DRY, YAGNI ('Don't build features before they're needed'), early returns, magic numbers, Promise.all parallelism, the AAA test pattern, memoization — which the guidelines explicitly penalize. It is not anchor 1's padded prose (examples are compact and example-driven), but the sheer volume of already-known material makes it noticeably verbose.

2 / 5

Actionability

Most examples are concrete and executable (the Button component, useDebounce hook, zod validation handler, supabase query), with good/bad contrast pairs. It falls short of anchor 5 because several examples are stubs — 'async function fetchMarketData(marketId: string) { }', '// Implementation' — and there is no guidance on applying the standards to real code.

4 / 5

Workflow Clarity

As a reference-style skill with no multi-step process, its sections are thematically organized, but there is no guidance on how to operationalize the standards (e.g., a checklist flow for writing vs. reviewing code), and the closing 'When to Use' section is vacuous filler: 'This skill is applicable to execute the workflow or actions described in the overview.' Not anchor 4's 'clear sequence with most checkpoints'; structure exists but application checkpoints are absent.

3 / 5

Progressive Disclosure

Headers provide real structure, but the entire surface — TypeScript/JS standards, React practices, API design, file organization, performance, testing, code smells — is inlined in one 525-line SKILL.md with no bundle files at all (no references/, scripts/, or assets/ exist). The under-50-line simple-skill exception does not apply, and content that clearly belongs in separate reference files is inline — anchor 3, short of anchor 4's 'most content appropriately placed.'

Description

52%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.

The description names its technology domains clearly and uses natural keywords, but it describes a topic category rather than concrete actions and provides no 'when to use' trigger guidance. It is also very broad, risking overlap with many coding-related skills.

Suggestions

Add an explicit trigger clause, e.g., 'Use when writing or reviewing TypeScript, JavaScript, React, or Node.js code, or when the user asks about coding standards or best practices.'

Replace generic category nouns with concrete actions, e.g., 'Applies naming conventions, typing, error-handling, and React state patterns; flags code smells like deep nesting and magic numbers.'

Narrow the trigger surface (e.g., 'for code review or new-code checklists in TS/JS/React/Node projects') to reduce overlap with general code-review and refactoring skills.

DimensionReasoningScore

Specificity

The description names the domains ("TypeScript, JavaScript, React, and Node.js") but the actions — "coding standards, best practices, and patterns" — are generic category nouns with no concrete verbs. This matches anchor 2 ('Names the domain but actions are minimal or generic'); it is above anchor 1 because the domains are explicitly named, but below anchor 3 because no concrete actions (e.g., 'review', 'refactor', 'enforce naming conventions') are stated.

2 / 5

Completeness

There is a reasonably clear 'what' (universal standards for four named stacks) but the 'when' is entirely absent — no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Not score 4, since even a weak 'when' is missing; not score 2, since the 'what' is more than vague.

3 / 5

Trigger Term Quality

"TypeScript", "JavaScript", "React", "Node.js", "coding standards", and "best practices" are natural terms users would actually say. It falls short of anchor 5's comprehensive synonym/extension coverage (no 'TS', 'tsx', 'clean code', 'linting'-style variations) but exceeds anchor 3's 'some relevant keywords' breadth.

4 / 5

Distinctiveness Conflict Risk

Naming four specific ecosystems makes it more specific than anchor 2's 'helps with document files' blandness, but "coding standards, best practices, and patterns" would plausibly fire on nearly any TS/JS/React/Node coding task, creating real overlap with code-review, refactoring, and language-specific skills. Somewhat specific with residual overlap risk — anchor 3.
