description: >
  Create an explainer video with narration using Pexo. Describe your product, concept, or process
  and Pexo writes the script, generates visuals shot by shot, adds TTS voiceover and captions, and
  assembles a clear, finished explainer. Use for explainer/tutorial content: "explainer video",
  "explain this as a video", "tutorial video", "how it works video". NOT for ads or promos (use
  the video-ad skill).

# 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-<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: "Explain how our budgeting app works in a 60-second video."

```bash
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.
```

## Scripts

| Script | Usage | Returns |
|---|---|---|
| `pexo-project-create.sh` | `"<brief>"` | `project_id` |
| `pexo-upload.sh` | `<project_id> <file>` | `asset_id` |
| `pexo-chat.sh` | `<project_id> "<message>" [--choice <id>]` | ack (async) |
| `pexo-project-get.sh` | `<project_id>` | JSON: `nextAction`, `recentMessages` |
| `pexo-asset-get.sh` | `<project_id> <asset_id>` | JSON with `url` |
| `pexo-doctor.sh` | — | setup diagnostic |
