Quality

Content

63%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 content is a well-sequenced, mostly actionable multi-phase workflow with concrete per-platform prompts, but it is a long monolithic document with some padded boilerplate and no progressive file split. Adding explicit error-recovery feedback loops and moving detailed platform specs into reference files would lift the weaker dimensions.

Suggestions

Remove the 'Extended thinking' paragraph and the generic 'Instructions' bullets, or replace them with skill-specific guidance, to tighten conciseness.

Add explicit feedback loops for batch/destructive operations (e.g. 'If parity testing in step 6 finds >5% variance, return to the failing platform step and re-implement').

Split the detailed per-platform implementation prompts into separate reference files (e.g. references/web.md, references/ios.md) and link them one level deep from SKILL.md to improve progressive disclosure.

DimensionReasoningScore

Conciseness

The bulk is concrete actionable prompts, but the 'Extended thinking' block (lines 10) and the generic 'Instructions' boilerplate ('Clarify goals... Apply relevant best practices...') add padding Claude does not need, matching 'mostly efficient but includes some unnecessary explanation'.

3 / 5

Actionability

Each step gives a concrete Task tool invocation with subagent_type and a detailed, stack-specific prompt, which is mostly executable; placeholders like '[previous output]', '[architecture doc]', and '$ARGUMENTS' require substitution, keeping it just short of copy-paste-ready at 5.

4 / 5

Workflow Clarity

The workflow is clearly sequenced into three phases with numbered steps and 'Context from previous' / 'Expected output' per step, and includes validation steps (testing in 6, parity checks, success criteria); it lacks explicit error-recovery feedback loops, so it does not reach 5.

4 / 5

Progressive Disclosure

The body is a ~200-line monolith with good section headers but no bundle files (references/scripts/assets absent) and per-platform prompts inlined that could live in separate reference files, matching 'some structure but content that should be separate is inline'.

Description

53%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 clearly states what the skill does but lacks an explicit 'Use when' trigger clause, which caps completeness and limits trigger-term quality. It is specific enough to its multi-platform niche to be mostly distinct from other skills.

Suggestions

Add an explicit 'Use when...' clause with concrete trigger phrases, e.g. 'Use when building a feature for multiple platforms (web, iOS, Android, desktop) and needing feature parity.'

Include natural synonyms users would say ('cross-platform', 'multi-platform') alongside the jargon to improve trigger-term quality.

Optionally list 1-2 more concrete capabilities to lift specificity from a clear-what toward comprehensive coverage.

DimensionReasoningScore

Specificity

The description names the domain ('web, mobile, and desktop platforms') and two concrete actions ('Build and deploy'), but does not enumerate the full set of capabilities, so it matches 'names domain and 1-2 concrete actions' rather than the multi-action anchor at 4.

3 / 5

Completeness

It gives a clear 'what' ('Build and deploy the same feature consistently across...') but provides no 'Use when...' trigger clause, and the rubric caps completeness at 3 when explicit trigger guidance is missing.

3 / 5

Trigger Term Quality

It includes relevant natural terms ('web, mobile, desktop', 'feature') but leans on jargon ('API-first architecture', 'parallel implementation strategies') and omits common synonyms a user would say ('cross-platform', 'multi-platform'), fitting 'some relevant keywords but missing common variations'.

3 / 5

Distinctiveness Conflict Risk

The cross-platform feature-parity niche is mostly distinct from generic skills, with only minor overlap risk against closely related web or mobile development skills, matching 'mostly distinct; minor overlap risk'.
