--- name: video-tool-extend description: "Extend or continue an existing HTTPS video with a prompt via WeryAI (video-extend). Use when the user wants to lengthen a clip with style and duration controls, not text-to-video from scratch." metadata: { "openclaw": { "emoji": "⏩", "primaryEnv": "WERYAI_API_KEY", "paid": true, "network_required": true, "requires": { "env": ["WERYAI_API_KEY"], "bins": ["node"], "node": ">=18" } } } tags: [video, weryai, video-tools] --- # WeryAI video tool — extend This skill is **self-contained**: it documents and runs **only** the **`extend`** workflow on an **existing** video given by URL. It is **not** text-to-video or image-to-video generation from scratch. **Entry script:** `scripts/video_extend.js` (alongside this `SKILL.md`). **Runtime:** `WERYAI_API_KEY`, Node.js 18+. **Inputs:** `video_url` must be a **public `https://` URL**; `prompt` is text. This script does not read local files and does not perform upload-file flows. ## What this package ships (verify before trust) Canonical layout for **this** skill only: - `SKILL.md`, `eval.yaml` - `scripts/video_extend.js` (**the only** runnable script in scope) If your copy also contains `scripts/video_gen.js`, `scripts/video_toolkits.js`, `references/WERYAI_VIDEO_API.md`, or other CLIs, those files are **not** part of this skill’s contract — they may come from another repo sync or an over-broad install. **Do not run** them when you only want extend; remove them or reinstall from a clean source. Inspect what you run: `node scripts/video_extend.js spec`. **Other tools** (multi-endpoint CLIs, local-file upload to growth/upload-file APIs, extra environment variables in those CLIs) are **out of scope** for this package. This skill’s script uses **only** `WERYAI_API_KEY` and public `https://` URLs. ## API surface (this tool only) - **Required:** `video_url` (public `https://` URL), `prompt` (string) - **Optional:** `style` — `anime`, `3d_animation`, `cyberpunk`, `comic`; `resolution` — `360p`, `540p`, `720p`, `1080p`; `duration` — `5` or `8` (seconds) - **Defaults:** `style=anime`, `resolution=720p`, `duration=5` From **this skill root**, run `node scripts/video_extend.js spec` to print the full tool schema (endpoint, required fields, defaults, enums) as JSON. ## Pre-submit gate (mandatory) Do **not** run `submit` / `wait` until the user explicitly confirms the video URL, prompt, and any non-default `style` / `resolution` / `duration`. Paid runs are not idempotent. ## Workflow Prefer `--dry-run` to validate JSON. Use `wait` to submit and poll until the task finishes; use `submit` only when the user wants a `task_id` without blocking, then `status` for later checks. Share final URLs as Markdown links `[Video](https://…)`. ## CLI From **this skill root**: ```sh node scripts/video_extend.js wait \ --json '{"video_url":"https://example.com/video.mp4","prompt":"Continue the motion naturally for 5 seconds"}' node scripts/video_extend.js submit \ --json '{"video_url":"https://example.com/video.mp4","prompt":"Continue the motion naturally for 5 seconds","style":"anime","duration":5,"resolution":"720p"}' node scripts/video_extend.js status --task-id <task-id> ``` Dry-run: ```sh node scripts/video_extend.js wait \ --json '{"video_url":"https://example.com/video.mp4","prompt":"Continue the motion naturally for 5 seconds"}' \ --dry-run ``` ## Security Never write `WERYAI_API_KEY` into files. Keep **only** `WERYAI_API_KEY` set for this workflow; do not rely on undocumented env vars in sibling scripts if any were mistakenly present. The in-scope script reads **only** `WERYAI_API_KEY` (no other env keys). **`video_extend.js`** accepts **only** `https://` media URLs (no disk read / no upload-file). Base URL and poll intervals are constants in the script, not env-driven. Do **not** pass local filesystem paths or run tools that accept them unless you have **explicitly** reviewed and consented to their upload behavior — that is never required for this skill. ## Out of scope - Any other WeryAI video-tool workflows - Pure text-to-video with **no** source video URL ## References - [WeryAI llms.txt](https://docs.weryai.com/llms.txt)
