Content & Media

Use when cypress CI/CD integration including parallelization, test recording, and media capture.

Use when hotwire (Turbo and Stimulus) for building modern reactive Rails applications without complex JavaScript frameworks.

Use during implementation when designing modules, functions, and components requiring SOLID principles for maintainable, flexible architecture.

Use when eSLint built-in rules including rule configuration, severity levels, and disabling strategies.

Multi-agent parallel investigation for complex JUCE problems. Use when troubleshooting fails after Level 3, problems require novel research, or user requests /research command.

Use when responding to questions or providing information requiring professional honesty and directness over excessive agreeableness.

Use when writing SOPs that require precise requirement levels using RFC 2119 constraint keywords (MUST, SHOULD, MAY). Covers proper usage of requirement keywords for deterministic agent behavior.

Use when optimizing React Native app performance. Covers FlatList optimization, memoization, image optimization, bundle size reduction, and profiling techniques.

Use when working with React Native Web projects. Provides core concepts, components, and cross-platform patterns for building web applications with React Native.

Use when configuring Expo apps with app.json, app.config.js, and EAS configuration. Covers app metadata, plugins, build configuration, and environment variables.

Validates audio plugins through automated tests, pluginval, or manual DAW testing. Use for MANUAL testing via /test command. Note - Automatic validation now built into workflow (validation-agent runs after each stage). This skill is for manual testing only, after bug fixes, or when user mentions test, validate, validation, pluginval, stability, automated tests, run tests, check plugin, or quality assurance.
