muapi-youtube-shortsAuto-generate viral 9:16 YouTube Shorts (or TikTok / Reels clips) from a long-form video.
Muapi Youtube Shorts is an agent skill from hashgraph-online/awesome-codex-plugins. Auto-generate viral 9:16 YouTube Shorts (or TikTok / Reels clips) from a long-form video. Thin platform-aware wrapper around the AI Clipping skill — picks sensible defaults for short-form social platforms (9:16, 30–60s sweet spot) and delegates the actual highlight extraction + crop to muapi.ai's /ai-clipping endpoint.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/run-youtube-shorts.sh`).
It sits in Media & Creative, covering Video scripts and shorts. It works with TikTok. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 3e1456a. It shows what the files ask for, not the result of running them.
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.
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
bashjqFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
youtube.comAlso links to:
github.commuapi.aiFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
MUAPI_API_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Muapi Youtube Shorts loads about 1.5k tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 574 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.
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.

This skill is a platform-aware preset over the AI Clipping primitive. It picks the right aspect ratio and clip count for the target platform and delegates highlight extraction, dedupe, and face-tracked auto-crop to muapi.ai's managed /ai-clipping endpoint.

| Use this skill when… | Use AI Clipping directly when… |
|---|---|
| Target is YouTube Shorts / TikTok / Reels | You want full control over aspect / count |
| You want platform-tuned defaults | You want raw timestamps (--coords-only) |
You'd rather pass --platform tiktok than think about ratios | You're integrating into a custom renderer |
| Input | Default | Notes |
|---|---|---|
--source | — | YouTube URL, hosted mp4 URL, or local file |
--platform | shorts | shorts | tiktok | reels | feed (sets ratio + count defaults) |
--num-clips | platform default | Override clip count |
--aspect-ratio | platform default | Override aspect ratio |
If the user gave only a URL, run with platform defaults — don't block.

--aspect-ratio / --num-clips aren't passed.muapi edit clipping (the /ai-clipping endpoint) with the chosen params.The /ai-clipping endpoint runs the full pipeline:
Each clip ships with score (0–100), opening hook line, and a one-sentence "why it works" reason.
| Platform | Flag | Aspect | Default clips | Notes |
|---|---|---|---|---|
| YouTube Shorts | --platform shorts | 9:16 | 3 | Hook in first 1s |
| TikTok | --platform tiktok | 9:16 | 5 | Higher energy, longer ok |
| Instagram Reels | --platform reels | 9:16 | 3 | Hook in first 1s |
| Instagram Feed | --platform feed | 1:1 | 3 | Static-feel works well |
Override any default with --aspect-ratio / --num-clips.

Auto-generate viral 9:16 YouTube Shorts (or TikTok / Reels clips) from a long-form video. Muapi Youtube Shorts is an agent skill from hashgraph-online/awesome-codex-plugins. Auto-generate viral 9:16 YouTube Shorts (or TikTok / Reels clips) from a long-form video.
Muapi Youtube Shorts fits situations like: tasks that involve Video scripts and shorts.
Run `npx skills add hashgraph-online/awesome-codex-plugins --skill muapi-youtube-shorts -a claude-code`. Or copy the skill folder (plugins/SamurAIGPT/Generative-Media-Skills/library/social/youtube-shorts in hashgraph-online/awesome-codex-plugins) into .claude/skills/muapi-youtube-shorts in your project. Claude Code loads it when a task matches its description.
Run `npx skills add hashgraph-online/awesome-codex-plugins --skill muapi-youtube-shorts -a codex`. Or copy the skill folder (plugins/SamurAIGPT/Generative-Media-Skills/library/social/youtube-shorts in hashgraph-online/awesome-codex-plugins) into .agents/skills/muapi-youtube-shorts in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add hashgraph-online/awesome-codex-plugins --skill muapi-youtube-shorts -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/muapi-youtube-shorts, .gemini/skills/muapi-youtube-shorts, .github/skills/muapi-youtube-shorts and .opencode/skills/muapi-youtube-shorts in your project.
Going by SKILL.md and its folder, Muapi Youtube Shorts needs a shell for the scripts in its folder, the command-line tools its instructions call (bash and jq) and credentials named MUAPI_API_KEY. Our summary lists: A Bash shell; A credential in MUAPI_API_KEY.
SKILL.md names 3 domains. In commands or code: youtube.com; the agent is likely to contact it when it follows the instructions. As links in the text: github.com and muapi.ai. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Muapi Youtube Shorts is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
