Explainer Video — Pexo
Pexo: https://pexo.ai — get an API key, watch your project render, and buy credits there.
Produce a clear, narrated explainer video. You relay the user's topic to the hosted Pexo agent and deliver the result; Pexo writes the script, generates the visuals shot by shot, and adds voiceover 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-\x3Cyour-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.
- Create a project:
pexo-project-create.sh "\x3Cshort brief>"→ save theproject_id. - Upload any files the user gave:
pexo-upload.sh \x3Cproject_id> \x3Cpath>→ saveasset_id, reference it inline as\x3Coriginal-image>asset_id\x3C/original-image>(or\x3Coriginal-video>/\x3Coriginal-audio>). Tags are required — a bareasset_idis ignored. Pexo can't crawl URLs — download, then upload. - Send the request:
pexo-chat.sh \x3Cproject_id> "\x3Cuser's exact words> \x3Casset tags>". Copy the user's words exactly; only add asset tags. - Tell the user (their language): submitted ✓ · ~15–20 min ·
https://pexo.ai/project/\x3Cproject_id>. - Poll: every ≥60s run
pexo-project-get.sh \x3Cproject_id>and act onnextAction:- 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, thenpexo-chat.shtheir reply); forpreview_video, runpexo-asset-get.sh \x3Cproject_id> \x3CassetId>per option, show the URLs (A/B/C), let the user pick, thenpexo-chat.sh \x3Cproject_id> "\x3Cchoice>" --choice \x3CassetId>; for adocumentevent, mention it to the user. - DELIVER →
pexo-asset-get.sh \x3Cproject_id> \x3Cfinal 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
nextActionHintin plain terms and offer to retry. - RECONNECT →
pexo-chat.sh \x3Cproject_id> "continue", tell the user the connection dropped and you're resuming, then keep polling. - Never call
pexo-chat.shduring 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 \x3Cproject_id> "\x3Ctheir 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: "Explain how our budgeting app works in a 60-second video."
pid=$(pexo-project-create.sh "budgeting app explainer")
pexo-chat.sh "$pid" "Explain how our budgeting app works in a 60-second video."
# 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.
