media-accessibility
Video, audio, and streaming media accessibility specialist. Audits captions (WebVTT/SRT), transcripts, audio descriptions, accessible media player controls, live captioning, and WCAG 1.2.x time-based media criteria.
What this skill does
Derived from `.claude/agents/media-accessibility.md`. Treat platform-specific tool names or delegation instructions as Codex equivalents. # Media Accessibility Specialist You audit video, audio, and multimedia content for accessibility. Covers captions, transcripts, audio descriptions, media player controls, and live captioning — the full WCAG 1.2.x domain. ## WCAG 1.2 Coverage | SC | Level | Requirement | |----|-------|-------------| | 1.2.1 | A | Transcript for audio-only/video-only | | 1.2.2 | A | Captions for prerecorded video | | 1.2.3 | A | Audio description or text alternative | | 1.2.4 | AA | Captions for live video | | 1.2.5 | AA | Audio descriptions for prerecorded video | ## Audit Checklist 1. Find all `<video>`, `<audio>`, `<iframe>` (embedded media) elements 2. Check each `<video>` for `<track kind="captions">` — missing = Critical 3. Verify caption files exist and are valid (WebVTT/SRT syntax) 4. Check for `<track kind="descriptions">` for audio descriptions 5. Audit media player controls: keyboard accessibility, ARIA labels, state management 6. Check for autoplay: audio >3s must have pause/stop/volume control (WCAG 1.4.2) 7. Verify transcripts exist for audio-only content ## Caption Quality - 99%+ accuracy, synchronized within 1 second - Speaker identification for 2+ speakers - Non-speech audio in brackets: `[applause]`, `[music]` - Maximum 200 words/minute, 32 chars/line, 2 lines/caption ## Media Player ARIA - Play/Pause: `role="button"`, `aria-label` reflects state - Volume: `role="slider"` with min/max/now values - Seek: `role="slider"`, `aria-valuetext` for time - Captions toggle: `aria-pressed` - State announcements via `aria-live="polite"` region

watch
IncludedWatch a video (URL or local path). Downloads with yt-dlp, extracts auto-scaled frames with ffmpeg, pulls the transcript from captions (or Whisper API fallback), and hands the result to Claude so it can answer questions about what's in the video.
physical-ai-defect-image-generation
IncludedUse when the user wants to orchestrate defect image generation, run associated setup, or handle outputs on OSMO. The Day 0 path handles cold-start with USD-to-ROI, image-edit augmentation, and AnomalyGen to create initial PCBA datasets. The Day 1 path performs inference and labeling on real images. This skill helps with first-time asset setup, creation of finetuning checkpoints, and configuring deployment. Trigger keywords: defect image generation, dig workflow, dig pipeline, defect image detection workflow, aoi pipeline, aoi anomalygen, usd2roi anomalygen, day 0 pcba, day 1 pcba, day 1 real-photo alignment, day 1 manual roi, metal surface anomaly, glass defect, anomalygen finetune, setup_pcb, setup_metal, setup_glass, setup_pretrained, dig setup, dig datasets, dig pretrained checkpoint, dig image-edit endpoint.
accelint-react-best-practices
IncludedReact performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies. Even simple React tasks benefit from these patterns. Covers React 19+ (useEffectEvent, Activity, ref props). Triggers - useEffect, useState, useMemo, useCallback, memo, inline components, nested components, components inside components, re-render, performance, hydration, SSR, Next.js, useDeferredValue, combined hooks.
elevenlabs-agents
IncludedBuild conversational AI voice agents with ElevenLabs Platform using React, JavaScript, React Native, or Swift SDKs. Configure agents, tools (client/server/MCP), RAG knowledge bases, multi-voice, and Scribe real-time STT. Use when: building voice chat interfaces, implementing AI phone agents with Twilio, configuring agent workflows or tools, adding RAG knowledge bases, testing with CLI "agents as code", or troubleshooting deprecated @11labs packages, Android audio cutoff, CSP violations, dynamic variables, or WebRTC config.

humanizer
IncludedHumanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.
generating-mermaid-diagrams
IncludedSalesforce architecture diagrams using Mermaid with ASCII fallback. Use this skill when generating text-based diagrams for Salesforce architecture, OAuth flows, ERDs, integration sequences, or Agentforce structure. TRIGGER when: user says "diagram", "visualize", "ERD", or asks for sequence diagrams, flowcharts, class diagrams, or architecture visualizations in Mermaid. DO NOT TRIGGER when: user wants PNG/SVG image output (use generating-visual-diagrams), or asks about non-Salesforce systems.
