gif-analyzer
Analyze animated GIF files by extracting and viewing frames as sequential video. Use when: - User mentions a GIF file path (e.g., "./demo.gif", "~/Downloads/animation.gif") - User wants to analyze or understand a GIF animation - User asks about motion, changes, or content in a GIF - User attaches or references a .gif file for analysis - User wants to examine a screen recording in GIF format - User invokes /gif slash command Keywords: "GIF", ".gif", "animation", "animated", "frames", "screen recording", "analyze gif", "gif analysis", "view gif", "gif content", "gif motion" Trigger patterns: - Natural language: "Analyze this GIF: ./demo.gif" - Slash command: `/gif <path>` or `/gif <path> <message>` When triggered, extract frames using the Python script, view frames in order, and interpret as continuous video sequence.
What this skill does
# GIF Analyzer Analyze animated GIFs by extracting frames and interpreting them as sequential video. ## Quick Start When the user uses `/gif`: **Pattern 1: Basic analysis** ``` /gif ./animation.gif ``` **Pattern 2: With specific request** ``` /gif ./animation.gif describe what happens step by step /gif ./demo.gif what is the character doing? /gif ./screen.gif summarize this screen recording ``` ## Workflow ### Step 1: Parse User Input Extract from the user's message: 1. **GIF path**: The file path immediately after `/gif` 2. **User request** (optional): Any text after the GIF path Example parsing: - Input: `/gif ./demo.gif explain the animation` - GIF path: `./demo.gif` - User request: `explain the animation` ### Step 2: Extract Frames ```bash python3 scripts/extract_gif_frames.py <gif_path> --output-dir /tmp/gif_frames_analysis ``` Options for long GIFs: ```bash python3 scripts/extract_gif_frames.py <gif_path> --max-frames 30 --skip 2 ``` ### Step 3: Read Metadata Check `gif_metadata.json` for: - Total frames and duration - Individual frame timestamps - Resolution and loop information ### Step 4: View and Analyze Frames View frames in order: `frame_001.png`, `frame_002.png`, etc. **CRITICAL**: Treat frames as a continuous video sequence: 1. **Frame 001 = START** of the animation 2. **Frame numbers increase in TIME ORDER** 3. **Consecutive frames show MOTION/CHANGE over time** ### Step 5: Respond to User If user provided a specific request, focus on answering that. Otherwise, provide a general analysis of the GIF content. ## Script Options | Option | Description | Default | |--------|-------------|---------| | `--output-dir`, `-o` | Output directory | `./gif_frames_<timestamp>` | | `--max-frames`, `-m` | Max frames to extract | 50 | | `--skip`, `-s` | Extract every Nth frame | 1 (all frames) | ## Frame Analysis Guidelines 1. **Temporal Awareness**: Frame 001 is the beginning 2. **Motion Detection**: Compare adjacent frames to identify movement 3. **Key Frames**: Identify significant moments (start, middle, end) 4. **Loop Points**: Note if the animation appears to loop 5. **Duration Context**: Use timestamp info to understand pacing ## Output Format ``` **GIF Analysis: [filename]** **Overview:** [1-2 sentence summary] **Timeline:** - [0.0s - 0.5s] Frame 1-5: [Description] - [0.5s - 1.0s] Frame 6-10: [Description] ... **[Answer to user's specific question if provided]** ``` ## Troubleshooting - **Pillow not found**: `pip install Pillow` - **Too many frames**: Use `--skip 2` or higher - **Large output**: Use `--max-frames 20`

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.
