What it does
Yichen X Slicer is an agent skill from mcncarl/yichen-skills. 将公开 X 推文、Quote 或同作者 Thread 转为 1080×1440 图片切片和 MP4；也支持显式 source-only 素材桥接。保留所选原生视频及对应音频，不发布。
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `references/content-routing.md` and `references/source-only.md`).
It sits in Testing & QA. It works with Playwright.
When your agent uses it
- Testing & QA work in your project
Example prompts
- “/yichen-x-slicer”
Requirements
- Node.js
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Resolve the directory containing this SKILL.md as SKILL_DIR.
- Choose a new output directory under the current task's user-facing outputs/ directory. Never overwrite or delete an earlier run.
- Run. This default command generates the image sequence, image ZIP, and MP4
What it can do on your machine
Read from SKILL.md and the folder at commit 9bd7898. 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 3 files in scripts/ (JavaScript), which the agent can run.
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
Yichen X Slicer loads about 2.2k tokens when it runs, and up to ~6.4k if it reads all its reference files. Until then it costs about 27 tokens; SKILL.md has 1,147 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,147 words (~2,164 tokens).
“Turn one public X status URL into a complete 3:4 image sequence. Use sunset（落日琥珀版）unless the user explicitly chooses another template.”
