--- name: video-tool-background-remove description: "Remove or replace a video background with a solid color via WeryAI (video-background-remove). Use when the user wants background removal or a flat-color backdrop on an HTTPS video, not text-to-video." 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 — background remove This skill is **self-contained**: it documents and runs **only** the **`background-remove`** 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_background_remove.js` (alongside this `SKILL.md`). **Runtime:** `WERYAI_API_KEY`, Node.js 18+. **Inputs:** `video_url` must be a **public `https://` URL**. 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_background_remove.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 background-remove; remove them or reinstall from a clean source. Inspect what you run: `node scripts/video_background_remove.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) - **Optional:** `background_color` — `TRANSPARENT`, `BLACK`, `WHITE`, `GRAY`, `RED`, `GREEN`, `BLUE`, `YELLOW`, `CYAN`, `MAGENTA`, `ORANGE` - **Default:** `background_color=BLACK` From **this skill root**, run `node scripts/video_background_remove.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 and any non-default `background_color`. 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_background_remove.js wait \ --json '{"video_url":"https://example.com/video.mp4"}' node scripts/video_background_remove.js submit \ --json '{"video_url":"https://example.com/video.mp4"}' node scripts/video_background_remove.js status --task-id <task-id> ``` Dry-run: ```sh node scripts/video_background_remove.js wait \ --json '{"video_url":"https://example.com/video.mp4"}' \ --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_background_remove.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 (subtitles, upscale, extend, face change, etc.) - Text-to-video or image-to-video from scratch ## References - [WeryAI llms.txt](https://docs.weryai.com/llms.txt)
