modbender 🎬 YouTube AI Editor (v1.0.14)
⚠️ Security Notice
This skill may trigger security warnings due to legitimate automation features:
Required Capabilities:
- API Keys: Requires
OPENAI_API_KEY(mandatory for Whisper/GPT-4) andNANO_BANANA_KEY(optional for AI image generation) - Subprocess Execution: Uses ffmpeg for video processing (standard video editing tool)
- Cross-Skill Integration: Calls
nano-banana-proskill for AI image generation (optional feature)- Only executes if nano-banana-pro is installed by user
- Uses fixed script path resolution with timeout protection
- File I/O: Reads user-specified avatar/font files and writes output files (thumbnails, transcripts) to working directory
Security Measures:
- YouTube URL validation (blocks localhost/private IPs)
- HTML-escaped text rendering
- Subprocess timeouts (900s max)
- Fixed script paths (no arbitrary code execution)
All code is open source and auditable. Review nano-banana-pro separately if using image generation features.
