Content

80%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.

A well-structured, token-efficient skill body that routes Claude to substantive reference files via clear one-level-deep navigation. Its main weakness is the absence of explicit build/upload verification checkpoints in the workflow, which caps workflow clarity despite the otherwise clean sequencing.

Suggestions

Add an explicit verification checkpoint after the upload step (e.g., confirm `artifact-id` was captured and the artifact is listed via `gh api` or `actions/download-artifact`) to satisfy the batch-operation feedback-loop expectation and raise workflow_clarity.

Include a minimal inline copy-paste-ready workflow snippet (workflow_dispatch/pull_request triggers calling the composite actions) so the core orchestration is executable without opening a reference file, improving actionability.

Add a short troubleshooting/error-recovery note for common build failures (missing iOS scheme, gradlew not executable, expired artifact retention) to add the feedback loop the workflow currently lacks.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence — it never explains what GitHub Actions or React Native is, and every section (Overview, When to Apply, Quick Reference, mapping tables) earns its place, matching the lean-and-efficient anchor.

5 / 5

Actionability

Provides concrete executable pointers — named composite-action files, the exact workflow path `.github/workflows/mobile-build.yml`, `actions/upload-artifact@v4` with `artifact-id`, and the exact REST path — but the full executable YAML/code lives in the reference files rather than inline, leaving minor gaps.

4 / 5

Workflow Clarity

Quick Reference gives a clear four-step sequence (composites → wire workflow → upload → download) and Problem→Skill routing, but there is no validation/verification checkpoint for the batch build-and-upload operations; per the rubric cap this holds workflow_clarity at 3.

3 / 5

Progressive Disclosure

Clear overview with well-signaled one-level-deep references: a References table and a Problem→Skill mapping table both route to three real, substantive reference files, with content appropriately split and easy to navigate.

Description

88%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 concise, well-targeted description that names concrete capabilities and gives an explicit 'Use when' trigger clause tied to natural keywords. It is largely free of fluff and clearly carves out a distinct niche, with only minor missing synonyms/extensions keeping it from full marks on trigger and distinctiveness.

DimensionReasoningScore

Specificity

Names multiple concrete actions across a clearly scoped domain — 'React Native iOS simulator and Android emulator cloud builds with downloadable artifacts' plus retrieval via 'gh CLI and GitHub API' — matching the comprehensive-coverage anchor.

5 / 5

Completeness

Explicitly answers both what (RN iOS sim/Android emulator cloud build workflow patterns with downloadable artifacts) and when ('Use when setting up CI build pipelines or downloading GitHub Actions artifacts via gh CLI and GitHub API') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Strong natural keywords users would say ('GitHub Actions', 'CI build pipelines', 'iOS simulator', 'Android emulator', 'gh CLI', 'GitHub API'); a few natural variations such as explicit file extensions (.apk/.app) are absent, placing it just below the comprehensive anchor.

4 / 5

Distinctiveness Conflict Risk

The React Native mobile simulator/emulator CI niche with artifact-download framing is clearly distinct; only minor overlap risk with a generic gh-CLI or GitHub-Actions skill.
