安全亮点
✓ Pure bash script with no external script downloads or remote code execution
✓ No obfuscation, base64, or encoded payloads — all code is human-readable
✓ No credential, API key, or environment variable enumeration
✓ No network access (no curl, wget, or IP addresses)
✓ No file write outside user-specified output paths
✓ Uses only standard, well-known CLI tools (ffmpeg/ffprobe)
✓ SKILL.md documentation accurately describes all implemented functionality
✓ No hidden commands — all 5 subcommands (analyze/frame/cover/waveform/batch) match SKILL.md
✓ File writes are limited to user-specified output files with explicit paths
