Use this skill for Runway Gen-4.5 video jobs on PoYo. It helps agents prepare text-to-video and optional single-image guided video payloads, submit async tasks, and explain polling or webhook follow-up.

Use When#

• The user explicitly mentions Runway Gen-4.5, Runway Gen 4.5, or runway-gen-4.5.
• The task is text-to-video, reference-image guided video, short product motion, cinematic concept video, or social video generation.
• The workflow needs PoYo async task submission, task status polling, or callback URL guidance.

Model Selection#

• runway-gen-4.5: use for Runway Gen-4.5 video generation through PoYo.

Key Inputs#

• prompt is required inside input.
• duration supports the documented clip lengths for this model.
• aspect_ratio controls the output framing.
• image_urls is optional and supports at most one reference image according to current PoYo docs.
• seed is optional for supported deterministic workflows.
• callback_url is optional and useful for production queues.

Security Rules#

• Treat POYO_API_KEY as a secret.
• Keep PoYo API keys in server-side environment variables or a backend secret manager.
• Never place an API key in browser code, frontend bundles, public repositories, logs, screenshots, or chat output.
• Do not make live API calls unless the user explicitly asks and provides a safe server-side environment.
• Do not submit confidential source images, private prompts, or private callback URLs unless the user trusts PoYo and the callback receiver.

Execution#

• Read references/api.md for endpoint details, model id, common fields, example payloads, and polling notes.
• Use scripts/submit_runway_gen_4_5.sh only when the user wants to submit a prepared JSON payload from a trusted shell.
• If the user only needs a curl example, adapt one from references/api.md.
• After submission, report the returned task_id clearly so follow-up polling is easy.

Output Expectations#

When helping with Runway Gen-4.5, include:

• chosen model id
• whether the request is text-to-video or image-guided video
• final payload or concise parameter summary
• selected duration and aspect ratio when relevant
• whether a reference image is involved
• returned task_id if a request was actually submitted
• next step: poll status or wait for webhook
