Comprehensive spreadsheet creation, editing, and analysis with support for formulas, formatting, data analysis, and visualization. When Claude needs to work with spreadsheets (.xlsx, .xlsm, .csv, .tsv, etc) for: (1) Creating new spreadsheets with formulas and formatting, (2) Reading or analyzing data, (3) Modify existing spreadsheets while preserving formulas, (4) Data analysis and visualization in spreadsheets, or (5) Recalculating formulas
i18n (internationalization) toolkit for projects using i18next. Provides three main functions: (1) i18n-check - Detect hardcoded Chinese text in HTML/JS files, (2) i18n-fix - Replace hardcoded text with i18n markers, (3) i18n-sync - Align translation keys across multiple languages (zh-CN, en, ja, ko, zh-TW). Use when working on internationalization tasks, detecting untranslated strings, or syncing locale files.
Extract key frames (I-frames) from video files using FFmpeg command line tool. Use this skill when the user needs to pull out keyframes, thumbnails, or important frames from MP4, MKV, AVI, or other video formats for analysis, previews, or processing.
Extract, normalize, mix, and process audio tracks - audio manipulation and analysis
Analyze media file properties - duration, resolution, bitrate, codecs, and stream information
Apply video filters - scale, crop, watermark, speed, blur, and visual effects
Cut, trim, concatenate, and split video files - basic video editing operations
Convert media files between formats - video containers, audio formats, and codec transcoding
Comprehensive command-line tools for modifying and manipulating images, such as resize, blur, crop, flip, and many more.
Extract frames from video files and save them as images using OpenCV
Generate compression reports for video processing. Use when you need to create structured JSON reports with duration statistics, compression ratios, and segment details after video processing.
Video editing with ffmpeg including cutting, trimming, concatenating segments, and re-encoding. Use when working with video files (.mp4, .mkv, .avi) for: removing segments, joining clips, extracting portions, or any video manipulation task.
Transcribe video to timestamped text using Whisper tiny model (pre-installed).
Process videos by removing segments and concatenating remaining parts. Use when you need to remove detected pauses/openings from videos, create highlight reels, or batch process segment removals using ffmpeg filter_complex.
Extract audio from video files to WAV format. Use when you need to analyze audio from video, prepare audio for energy calculation, or convert video audio to standard format for processing.
Transcribe audio/video to text with word-level timestamps using OpenAI Whisper. Use when you need speech-to-text with accurate timing information for each word.
Process filler word annotations to generate video edit lists. Use when working with timestamp annotations for removing speech disfluencies (um, uh, like, you know) from audio/video content.
Combine visual features (face detection, lip movement analysis) with audio features to improve speaker diarization accuracy in video files. Use OpenCV for face detection and lip movement tracking, then fuse visual cues with audio-based speaker embeddings. Essential when processing video files with multiple visible speakers or when audio-only diarization needs visual validation.
Transcribe audio segments to text using Whisper models. Use larger models (small, base, medium, large-v3) for better accuracy, or faster-whisper for optimized performance. Always align transcription timestamps with diarization segments for accurate speaker-labeled subtitles.
Create professional PDF reports with text, tables, and embedded images using reportlab. Works with ANY LLM provider (GPT, Gemini, Claude, etc.).
