Discovers existing React component patterns (file structure, state management, naming conventions, prop patterns, TypeScript conventions) in a codebase before writing new components. Produces a "use these patterns" summary to ensure consistency. Use this skill when: - About to write a new React component - Before creating a new feature with multiple components - When unsure what patterns or conventions exist in a codebase - Before a code review to understand existing patterns

Reviews CSS/SCSS changes in the current branch for over-specificity, missed reuse opportunities, and over-engineered abstractions. Produces analysis findings and uses pm7y-ralph-planner to generate TASKS.md for autonomous execution. Use when reviewing CSS changes before commit or PR, or to audit existing styles. Supports @file syntax to target specific files.

Creates syntactically correct mermaid diagrams (flowchart, sequenceDiagram, classDiagram, stateDiagram, erDiagram, gantt, mindmap) following official specifications. Prevents common errors like special characters in labels, subgraph syntax, note misuse, and reserved words. Use when creating or editing mermaid diagrams in documentation or design files.

Discovers existing SCSS/CSS patterns (mixins, variables, utility classes, component patterns) in a codebase before writing new styles. Produces a "use these patterns" summary to ensure consistency and reuse. Use this skill when: - About to write new CSS/SCSS styles - Before creating a new component's styles - When unsure what design tokens or utilities exist - Before a CSS review to understand existing patterns

Explicitly simplifies code by removing unnecessary abstractions, inlining single-use functions, reducing nesting, and applying YAGNI. Produces cleaner, more maintainable code. Use this skill when: - Code feels over-engineered or hard to follow - There are unnecessary abstractions or indirection - Functions are used only once and could be inlined - Nesting is deep and could be flattened - Code has speculative features that aren't needed

Download YouTube video transcripts and create structured summaries when user provides a YouTube URL or asks to download/get/fetch a transcript from YouTube. Also use when user wants to transcribe or get captions/subtitles from a YouTube video.
