testland/detox-testing

Authors React Native E2E tests with Detox (Wix) - gray-box architecture (runs in-process with the app), `element(by.id|by.text|by.label)` matchers, `waitFor()` for explicit sync beyond Detox's automatic async tracking, Jest runner. Use when the app is React Native and speed matters. For Flutter use flutter-testing; for black-box cross-platform use appium-testing; for YAML-declarative flows use maestro-flows; for non-RN native use xcuitest-suite or espresso-suite.

Content

85%

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

An actionable, well-sequenced skill body with executable code, explicit build/test verification feedback loops, and proper one-level-deep reference disclosure. The only weakness is mild verbosity in the introductory gray-box explanation and Limitations, which restate concepts Claude could infer.

Suggestions

Tighten the opening paragraph on gray-box architecture to the load-bearing differentiator only ('runs in-process, auto-syncs async ops') and drop the Appium comparison that Claude can infer.

Compress the 'Limitations' section into terse bullets without restating trade-offs already implied by the architecture description.

Consider moving the 'Anti-patterns' table rationale column to a single phrase each to cut tokens while keeping the fix guidance.

DimensionReasoningScore

Conciseness

The bulk is lean executable commands and code, but the opening gray-box-vs-Appium paragraph and parts of 'Limitations' explain concepts (e.g. 'automatically monitors asynchronous operations to eliminate test flakiness at its core') that Claude can largely infer, fitting 'Mostly efficient but includes some unnecessary explanation'.

2 / 3

Actionability

Fully executable guidance throughout — real `npm install`/`npx detox init`/`detox build --configuration` commands, complete Jest specs with `element(by.id(...))` and `expect(...).toHaveText(...)`, `waitFor` examples, and a CI YAML — matching 'Fully executable code/commands; copy-paste ready'.

3 / 3

Workflow Clarity

A clear 7-step sequence with explicit validation checkpoints and feedback loops — Step 2's 'If it fails, fix the underlying native build error... and re-run' and Step 6's 'If one fails, read the Detox error, fix the matcher or add a waitFor, and re-run' — matching the 'Clear sequence with explicit validation steps; feedback loops for error recovery' anchor.

3 / 3

Progressive Disclosure

SKILL.md is an overview that offloads the matcher/action/assertion catalog to a real, clearly signaled one-level-deep reference (`[references/element-api.md](references/element-api.md)`), with content appropriately split and easy navigation, 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 highly specific, third-person description that covers concrete capabilities, natural trigger terms, and explicit when-to-use guidance, while clearly distinguishing itself from sibling testing skills. It satisfies every dimension at the top anchor with no over-claims or fluff.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Authors React Native E2E tests', 'gray-box architecture (runs in-process with the app)', `element(by.id|by.text|by.label)` matchers, `waitFor()` for explicit sync, Jest runner — matching the 'Lists multiple specific concrete actions' anchor.

3 / 3

Completeness

Explicitly states what ('Authors React Native E2E tests with Detox...') and when ('Use when the app is React Native and speed matters'), matching the 'Clearly answers both what AND when with explicit triggers' anchor.

3 / 3

Trigger Term Quality

Natural terms users would say are well-covered ('E2E tests', 'React Native', 'speed matters') alongside comparative triggers ('For Flutter use flutter-testing; for black-box cross-platform use appium-testing'), fitting the 'Good coverage of natural terms' anchor.

3 / 3

Distinctiveness Conflict Risk

Clear RN+Detox niche with explicit disambiguation against flutter-testing, appium-testing, maestro-flows, xcuitest-suite, and espresso-suite, making wrong-skill triggering unlikely.
