What it does
Video Frames is an agent skill from iflytek/skillhub. Extract a single frame from a local video at the first frame, a timestamp, or a zero-based frame index using FFmpeg.
Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `NOTICE.md` and `scripts/frame.sh`).
It sits in Media & Creative, covering Video production. It works with FFmpeg. The repository describes itself as: Self-hosted, open-source agent skill registry for enterprises. Publish & version skill packages, govern with RBAC and audit logs, deploy on-premise with Docker or Kubernetes. The licence is MIT.
When your agent uses it
- Tasks that involve Video production
Example prompts
- “/video-frames”
Requirements
- A Bash shell
What it can do on your machine
Read from SKILL.md and the folder at commit 7352597. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
bash
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Video Frames loads about 238 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 80 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Video Frames (ffmpeg)
Extract a single frame from a video, or create quick thumbnails for inspection.
Quick start
First frame:
bash scripts/frame.sh /path/to/video.mp4 --out /tmp/frame.jpgAt a timestamp:
bash scripts/frame.sh /path/to/video.mp4 --time 00:00:10 --out /tmp/frame-10s.jpgAt a zero-based frame index:
bash scripts/frame.sh /path/to/video.mp4 --index 42 --out /tmp/frame-42.pngNotes
- Prefer
--timefor "what is happening around here?". - Use a
.jpgfor quick share; use.pngfor crisp UI frames. --indexaccepts a non-negative integer only.- The script never overwrites an existing output. Choose a new path or remove the old file only after the user explicitly asks to replace it.
