Quality

Content

82%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 highly actionable with executable commands and a clear eas.json example, well-organized into navigable sections; its main gaps are minor verbosity and the absence of explicit validation checkpoints in the build workflow.

DimensionReasoningScore

Conciseness

The body is mostly lean with commands and minimal conceptual padding, though a few lines restate obvious outcomes (e.g. "This will: 1. Build the development client in the cloud...") that could be trimmed.

4 / 5

Actionability

Concrete, copy-paste-ready commands cover the common cases (eas build with --profile/--local/--submit, adb install, xcrun simctl install, ideviceinstaller) with a complete eas.json example.

5 / 5

Workflow Clarity

Multi-step flows (TestFlight submit, local install) are clearly numbered and sequenced with a troubleshooting section for error recovery, but explicit validation checkpoints before/after builds are only implicit rather than stated.

4 / 5

Progressive Disclosure

Well-organized single-file structure with clear section headers and no nested references; exceeds the simple-skill line count so it does not qualify for the 5-point exception, but placement is appropriate and easy to navigate.

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 is concise and names a clear, distinct niche, but it lacks an explicit trigger ("Use when...") clause and omits common synonym terms, leaving completeness and trigger-term quality at the midpoint.

Suggestions

Add a 'Use when...' clause naming concrete triggers, e.g. 'Use when your app needs custom native code not supported by Expo Go, or when distributing a dev build via TestFlight'.

Include natural synonyms users say ('dev client', 'EAS build', 'development build') to broaden trigger coverage.

Mention one or two more concrete actions (e.g. configuring eas.json, installing on simulator/device) to lift specificity toward comprehensive coverage.

DimensionReasoningScore

Specificity

"Build and distribute Expo development clients locally or via TestFlight" names the domain and two concrete actions (build, distribute) with two delivery channels, but coverage is not comprehensive (no mention of configuration, credentials, or local install).

3 / 5

Completeness

A clear "what" is present (build and distribute dev clients) but there is no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3 per the rubric.

3 / 5

Trigger Term Quality

Includes relevant terms ("Expo development clients", "TestFlight") but omits common natural variations users say such as "dev client", "EAS build", "development build", or file/extension synonyms.

3 / 5

Distinctiveness Conflict Risk

The "Expo development clients" + "TestFlight" niche is mostly distinct from generic Expo skills, with only minor overlap risk against broader EAS/Expo build skills.
