Based on SOC occupation classification
This skill should be used for advanced LLM evaluation: LLM-as-judge systems, direct scoring, pairwise comparison, rubric calibration, evaluator bias mitigation, confidence scoring, and automated quality assessment.
Automated end-to-end UI testing and verification on an Android Emulator using ADB.
This skill should be used when modeling agent mental states with BDI concepts: beliefs, desires, intentions, RDF-to-belief transformations, rational agency traces, cognitive agents, BDI ontologies, and neuro-symbolic AI integration.
Build a premium cinematic landing page with mouse-scrub video hero and brand-driven narrative-arc sections. Use whenever the user provides a hero video plus a product / subject / brand and wants a landing page, promo site, product showcase, marketing page, or storytelling site. Works for any language and any subject. The signature effect is mouse-driven video scrubbing — the hero video lives across the entire page as a fixed backdrop, and moving the mouse left-right scrubs the video timeline so the subject responds to the cursor. Below the hero, 4-5 fully-opaque sections each carry their own brand identity (color, typography emphasis, layout pattern) and walk the viewer through a narrative arc (e.g. longing -> joy -> nostalgia -> contemplation -> action). Do NOT use for parallax frame-scrub landings where the page itself doesn't scroll (use parallax-landing-page instead) or for video editing / captioning workflows (use video-edit).
Convert frontend code (Vite, React, etc.) to a Stitch Design by chaining static HTML extraction, design system extraction, and file upload. **ALWAYS** use this skill when the user's intent is to move existing web apps or React components into Stitch (e.g., requests to "save", "migrate", or "upload"). You must use this skill even for simple "save" operations, as it is the only way to ensure the design system is extracted and assets are properly linked.
This skill should be used for diagnosing and mitigating context degradation: lost-in-middle failures, context poisoning, context clash, context confusion, attention-pattern issues, and agent performance degradation caused by accumulated or conflicting context.

Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Show progress for operations longer than a second or two.
Determinate when duration/percentage is known. A filling progress bar gives users a clear sense of remaining work. Use for downloads, uploads, or any measurable process.
Indeterminate when duration is unknown. A spinner communicates work is happening without promising a timeframe. Use for unpredictable network requests.
Prefer progress bars over spinners. Determinate progress feels faster and more trustworthy.
Place indicators where content will appear. Inline progress near the content area, not modal or distant.
Don't stack multiple indicators. Aggregate simultaneous operations into one representation or show the most relevant.
Don't hide the status bar without good reason. Reserve hiding for immersive experiences (full-screen media, games, AR).
Match status bar style to your content. Light or dark for adequate contrast.
Respect safe areas. No interactive content behind the status bar.
Restore promptly when exiting immersive contexts.
Activity rings are for Move, Exercise, and Stand goals. Don't repurpose the ring metaphor for unrelated data.
Respect ring color conventions. Red (Move), green (Exercise), blue (Stand) are strongly associated with Apple Fitness.
Use HealthKit APIs for activity data rather than manual tracking.
Celebrate completions with animation and haptics when rings close.
