Video Thumbnail Generator is an agent skill from 0xsline/OpenChatCut. Create platform-ready thumbnails from real video frames. Use when the user wants a thumbnail, cover image, YouTube cover, Shorts cover, Bilibili cover, Xiaohongshu cover, or other video poster image.
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Social media graphics and Video production. It works with Bilibili, Xiaohongshu and YouTube. The repository describes itself as: Open-source, local-first conversational AI video editor with a professional multi-track timeline, Agent Skills, MCP integration, and Remotion rendering. The licence is AGPL-3.0.
When your agent uses it
- The user wants a thumbnail
- Xiaohongshu cover
- Other video poster image
Example prompts
- “/video-thumbnail-generator”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Use the real video as visual evidence.
- Read style references before recommending styles.
- Keep text short and readable.
What it can do on your machine
Read from SKILL.md and the folder at commit 2e6f4a2. 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
No scripts in the folder and no shell commands in SKILL.md.
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 Thumbnail Generator loads about 713 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 273 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); files beside SKILL.md are not scanned.

Non-Negotiables
Use the real video as visual evidence.

- Inspect candidate frames:
- expressive face
- product or UI clearly visible
- dramatic action moment
- clean composition
- strong lighting or clear subject separation
- Classify the thumbnail job:
