What it does
Cover Thumbnail is an agent skill from luzhenqian/ai-coding-lab. Use when producing the deliverables for a video episode — the cover thumbnail AND/OR the per-platform marketing copy (Bilibili / YouTube / 小红书 / 视频号 titles, descriptions, tags). Both live as a single "preset" in creative/cover-generator/. Locks the channel's visual + editorial style. Always edit via the React app (cover-generator), never hand-roll HTML or copy-paste-edit per-platform copy from scratch.
Its SKILL.md is about 3k 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 Writing & Content, covering Copywriting. It works with YouTube, Bilibili and React. The repository describes itself as: 适合所有人的 AI 编程、AI 应用开发的实战教程——从 Vibe Coding 到 Agent、RAG，循序渐进，边学边做。
When your agent uses it
- Tasks that involve Copywriting
Example prompts
- “preset”
- “/cover-thumbnail”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Pick a theme and variant first. Theme = chrome accent. Variant = right-side structure. Don't reuse the previous episode's theme…
- Create creative/cover-generator/src/lib/presets/ep0X-.ts. Export both halves
- Register it in creative/cover-generator/src/lib/presets/index.ts — prepend to PRESETS so it becomes the default
- Run npm run dev (or just refresh — Vite hot-reloads). User picks the new entry from the dropdown, switches to 封面 for thumbnail export, and…
What it can do on your machine
Read from SKILL.md and the folder at commit a33cbe8. 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
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
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
Cover Thumbnail loads about 3k tokens when it runs. Until then it costs about 105 tokens; SKILL.md has 1,244 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,244 words (~3,022 tokens).
“If the user just wants a generic graphic that does NOT need to match the channel's identity, this skill does not apply.”
