What it does

Youtube Short Maker is an agent skill from pexoai/pexo-skills. Make YouTube Shorts that hold attention with Pexo — vertical 9:16, fast-paced, hook in the first 3 seconds. Describe your topic and Pexo writes the script, generates the shots, picks the models, and assembles a finished Short with music and captions. Use for YouTube Shorts: "youtube short", "make a youtube short", "shorts video", "short-form video". NOT for long-form or landscape video.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts and reference files (for example `README.md`, `references/SETUP-CHECKLIST.md` and `references/TROUBLESHOOTING.md`).

It sits in Media & Creative, covering Video scripts and shorts. The repository describes itself as: A collection of open-source Agent Skills for content creation — images, audio, and video. The licence is MIT.

When your agent uses it

  • YouTube Shorts: youtube short
  • Make a youtube short
  • Short-form video

Example prompts

  • “youtube short”
  • “make a youtube short”
  • “shorts video”
  • “/youtube-short-maker”

Requirements

  • A Bash shell
  • A credential in PEXO_API_KEY

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Create a project: pexo-project-create.sh "" → save the project_id.
  2. Upload any files the user gave: pexo-upload.sh → save asset_id,
  3. Send the request: pexo-chat.sh " ".
  4. Tell the user (their language): submitted ✓ · ~15–20 min · https://pexo.ai/project/.
  5. Poll: every ≥60s run pexo-project-get.sh and act on nextAction

What it can do on your machine

Read from SKILL.md and the folder at commit f724267. 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 9 files in scripts/ (Shell), which the agent can run.

    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:

    • pexo.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • PEXO_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Youtube Short Maker loads about 1.3k tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 102 tokens; SKILL.md has 536 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~102
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5k

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.

YouTube Short Maker — Pexo

Pexo: https://pexo.ai — get an API key, watch your project render, and buy credits there.

Make a finished YouTube Short built to retain — vertical and hook-first. You pass the user's topic to the hosted Pexo agent and deliver the result; Pexo scripts it, generates the shots, and assembles the Short with music and captions.

Your role: relay, don't create

Create a project, send the user's request verbatim, poll, deliver. Pexo's backend handles all creative work — scriptwriting, model choice, prompts, music. Adding your own direction (duration, style, models the user didn't ask for) overrides its judgment and produces worse videos.

Config

~/.pexo/config:

PEXO_BASE_URL="https://pexo.ai"
PEXO_API_KEY="sk-<your-api-key>"

No account / first run → read references/SETUP-CHECKLIST.md and walk the user through it — it carries the signup flow with the invite code that grants new users bonus credits, plus how to create the config above. Config error → run scripts/pexo-doctor.sh and follow its output.

Workflow

Scripts live in this skill's scripts/. Reply to the user in their language.

  1. Create a project: pexo-project-create.sh "<short brief>" → save the project_id.
  2. Upload any files the user gave: pexo-upload.sh <project_id> <path> → save asset_id, reference it inline as <original-image>asset_id</original-image> (or <original-video> / <original-audio>). Tags are required — a bare asset_id is ignored. Pexo can't crawl URLs — download, then upload.
  3. Send the request: pexo-chat.sh <project_id> "<user's exact words> <asset tags>". Copy the user's words exactly; only add asset tags.
  4. Tell the user (their language): submitted ✓ · ~15–20 min · https://pexo.ai/project/<project_id>.
  5. Poll: every ≥60s run pexo-project-get.sh <project_id> and act on nextAction:
    • WAIT → keep polling; every ~5 polls send a one-line update with the project link.
    • RESPOND → handle each event in recentMessages: relay Pexo's text (wait for the user's answer if it asked, then pexo-chat.sh their reply); for preview_video, run pexo-asset-get.sh <project_id> <assetId> per option, show the URLs (A/B/C), let the user pick, then pexo-chat.sh <project_id> "<choice>" --choice <assetId>; for a document event, mention it to the user.
    • DELIVER → pexo-asset-get.sh <project_id> <final assetId>, then send the user the full asset URL as plain text — all ?… query params, never truncated or wrapped in markdown — plus the project link.
    • FAILED → explain nextActionHint in plain terms and offer to retry.
    • RECONNECT → pexo-chat.sh <project_id> "continue", tell the user the connection dropped and you're resuming, then keep polling.
    • Never call pexo-chat.sh during WAIT — it triggers duplicate production.
    • Taking too long → if it's been >30 min and still WAIT, tell the user (with the project link + https://pexo.ai/connect/openclaw) it's running long; ask whether to keep waiting or stop. Don't poll forever.

Revisions

After delivery, the user's tweaks ("make it shorter", "new music", "different shot") reuse the same project: pexo-chat.sh <project_id> "<their feedback>", then poll again (step 5). Never create a new project for a revision — it throws away Pexo's server-side context.

Credits

If a script fails with "Credits balance" / "Insufficient credits": if the error carries a purchase link, pass it to the user; otherwise tell them to add credits at https://pexo.ai/home → Credits → Buy Credits. Retry after they confirm.

Example

User: "Make a YouTube Short on 3 quick tips for better sleep."

bash
pid=$(pexo-project-create.sh "better sleep tips short")
pexo-chat.sh "$pid" "Make a YouTube Short on 3 quick tips for better sleep."
# Tell the user: submitted, ~15–20 min, https://pexo.ai/project/$pid
# Poll pexo-project-get.sh "$pid" until nextAction is DELIVER, then deliver the asset URL.
