| Task | Tool | Reason |
|---|---|---|
| Video encoding/conversion | FFmpeg | Native codec support, streaming |
| Audio extraction/conversion | FFmpeg | Direct stream manipulation |
| Image resize/effects | ImageMagick | Optimized for still images |
| Background removal | RMBG | AI-powered, local processing |
| Batch images | ImageMagick | mogrify for in-place edits |
| Video thumbnails | FFmpeg | Frame extraction built-in |
| GIF creation | FFmpeg/ImageMagick | FFmpeg for video, ImageMagick for images |
# macOS
brew install ffmpeg imagemagick
npm install -g rmbg-cli
# Ubuntu/Debian
sudo apt-get install ffmpeg imagemagick
npm install -g rmbg-cli
# Verify
ffmpeg -version && magick -version && rmbg --version
# Video: Convert/re-encode
ffmpeg -i input.mkv -c copy output.mp4
ffmpeg -i input.avi -c:v libx264 -crf 22 -c:a aac output.mp4
# Video: Extract audio
ffmpeg -i video.mp4 -vn -c:a copy audio.m4a

Use for technology evaluation, best practices research, solution design, scalability/security/maintainability analysis.
Fast codebase scouting using parallel agents. Use for file discovery, task context gathering, quick searches across directories. Supports internal (Explore) and external (Gemini/OpenCode) agents.
Analyze images/audio/video with Gemini API (better vision than Claude). Generate images (Imagen 4), videos (Veo 3). Use for vision analysis, transcription, OCR, design extraction, multimodal AI.
Manage MCP servers - discover, analyze, execute tools/prompts/resources. Use for MCP integrations, intelligent tool selection, multi-server management, context-efficient capability discovery.
Brainstorm solutions with trade-off analysis and brutal honesty. Use for ideation, architecture decisions, technical debates, feature exploration, feasibility assessment, design discussions.
Review code quality, receive feedback with technical rigor, verify completion claims. Use before PRs, after implementing features, when claiming task completion. Includes scout-based edge case detection.
