Multimedia handling with the Mediabunny library. An agent skill from guanyang/open-agent-hub.
- Agent Workflows work in your project
- SKILL.md covers Getting audio duration, Getting video dimensions and Getting video duration
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Mediabunny is an agent skill from guanyang/open-agent-hub. Multimedia handling with the Mediabunny library
Its SKILL.md is about 190 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `get-audio-duration.md`, `get-video-dimensions.md` and `get-video-duration.md`).
It sits in Agent Workflows. The repository describes itself as: A lightweight, zero-dependency CLI tool to manage and activate capabilities for AI coding assistants (such as Claude Code, Cursor, Trae, etc.). The licence is MIT.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/mediabunny”
What it can do on your machine
Read from SKILL.md and the folder at commit acd7c6c. 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
Links to these hosts (documentation or services it may open):
mediabunny.dev
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
Mediabunny loads about 191 tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 74 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.
