What it does
Video Downloader is an agent skill from isjiamu/jiamu-skills. Download videos from 1000+ websites (YouTube, Bilibili, Twitter/X, TikTok, etc.) using yt-dlp. Use this skill when users provide video URLs and want to download videos, extract audio, or need help with video download issues.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/platform-tips.md` and `scripts/download.py`).
It sits in Media & Creative, covering Video production. It works with X (Twitter), YouTube, Bilibili and TikTok. The repository describes itself as: 甲木常用的 Agent Skills 集合，包含日常工作流中积累的高效技能扩展。 / A curated collection of Agent Skills for daily productivity workflows. The licence is MIT.
When your agent uses it
- Users provide video URLs and want to download videos
- Need help with video download issues
Example prompts
- “/video-downloader”
Requirements
- Python 3
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Browser cookies (recommended)
- PO token provider (for persistent access)
What it can do on your machine
Read from SKILL.md and the folder at commit 3c21371. 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/ (Python), which the agent can run.
Shell commands in SKILL.md call:
yt-dlppython3brewpip
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
bilibili.comtwitter.com
Also links to:
github.com
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 Downloader loads about 1.2k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 242 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.
