auth0-expo

Use when adding Auth0 login, logout, or session management to an Expo app. Integrates react-native-auth0 with the Expo Config Plugin for native iOS/Android builds — use even if the user says "add login to my Expo app" without mentioning the SDK. Do not use for bare React Native CLI projects.

Quality

Content

85%

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

The body is a well-structured, highly actionable integration guide with a clearly sequenced workflow and robust build-verification feedback loop, plus a clean three-file progressive-disclosure structure. Its only weakness is conciseness: the inline code example and some agent-instruction blocks run longer than necessary.

Suggestions

Trim the inline Auth0Provider/HomeScreen example to the minimal code that demonstrates provider wrapping and useAuth0() usage, moving the full multi-state UI rendering into references/integration.md or references/api.md.

Condense the blockquoted agent instructions (steps 2 and 7) into terser bullet form — keep the decisions and commands, drop the surrounding prose framing.

Consider moving the 'Common Mistakes' table into a reference file or keeping only the top 3–4 highest-frequency mistakes inline to reduce SKILL.md token weight.

DimensionReasoningScore

Conciseness

The body is specific and free of generic concept explanations, but the full inline HomeScreen component (loading state, conditional UI rendering) and several verbose agent-instruction blockquotes could be trimmed or moved to references; it is mostly efficient yet could be tightened, matching the level-2 anchor rather than the 'every token earns its place' level-3 anchor.

2 / 3

Actionability

It provides copy-paste-ready, executable commands ('npx expo install react-native-auth0', 'npx expo prebuild --clean', 'npx expo run:ios'), a complete app.json plugin block, exact callback URL formats, and a full Auth0Provider/useAuth0 TypeScript example, matching the 'fully executable code/commands; copy-paste ready' anchor.

3 / 3

Workflow Clarity

The seven-step Quick Start is clearly sequenced with an explicit validation checkpoint (checking for expo-dev-client before proceeding) and a build-verify feedback loop ('Re-run the build after each fix... Track the number of build-fix iterations') with a 5–6 attempt failcheck, matching the level-3 anchor for fragile operations.

3 / 3

Progressive Disclosure

SKILL.md is a concise overview with one-level-deep references to setup.md, integration.md, and api.md, each clearly signaled in a 'Detailed Documentation' section; all three files exist and the deep-link anchor in setup.md resolves, matching the 'clear overview with well-signaled one-level-deep references' anchor.

Description

100%

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: it states concrete capabilities, provides explicit and natural-language triggers, and clearly bounds its scope with a negative-trigger guardrail. Voice is third-person throughout, so no specificity penalty applies.

DimensionReasoningScore

Specificity

The description names multiple concrete actions ('adding Auth0 login, logout, or session management') and the specific integration mechanism ('Integrates react-native-auth0 with the Expo Config Plugin for native iOS/Android builds'), matching the 'lists multiple specific concrete actions' anchor rather than the partial level-2 anchor.

3 / 3

Completeness

It explicitly answers both 'what' ('Integrates react-native-auth0 with the Expo Config Plugin...') and 'when' via an explicit 'Use when...' trigger, plus the reinforced trigger 'use even if the user says "add login to my Expo app" without mentioning the SDK', matching the level-3 anchor.

3 / 3

Trigger Term Quality

It embeds a near-verbatim natural user phrase — "add login to my Expo app" — alongside 'login, logout, session management' and 'Expo app', giving strong coverage of terms a user would actually say rather than mere technical jargon.

3 / 3

Distinctiveness Conflict Risk

It carves a clear niche ('Expo app', 'native iOS/Android builds') and explicitly excludes the adjacent case ('Do not use for bare React Native CLI projects'), making collision with sibling skills like auth0-react-native unlikely.
