Poyo Flux Schnell

FLUX Schnell text-to-image generation on PoYo / poyo.ai via https://api.poyo.ai/api/generate/submit; use when the user explicitly requests PoYo or flux-schnell for prompt-based image generation, output size, image count, PNG or JPEG output, async polling, or webhooks; do not use for image editing.

Use this skill for FLUX Schnell text-to-image jobs through PoYo. It helps agents prepare prompt-based payloads, validate output controls, submit async tasks, and explain polling or webhook follow-up.

Use When

• The user explicitly asks for PoYo, flux-schnell, or the PoYo FLUX Schnell API.
• The user wants that PoYo model for text-to-image generation without source images.
• The workflow needs a PoYo request payload, async task submission, status polling, or callback guidance.

Do Not Use When

• The request needs image editing, image-to-image conversion, or reference-image input; use a PoYo model that documents image_urls support instead.

Model Selection

• flux-schnell: text-to-image generation only.
• Do not include input.image_urls; current PoYo validation rejects image input for this model.

Key Inputs

• input.prompt is required.
• input.size controls documented presets or a supported custom WIDTHxHEIGHT value.
• input.n controls the requested output count when supported by the current service.
• input.output_format supports png or jpeg.
• callback_url is optional and useful for production queues.

Security Rules

• Treat POYO_API_KEY as a secret and keep it in a server-side environment variable or secret manager.
• Never place an API key in browser code, frontend bundles, public repositories, logs, screenshots, or chat output.
• Do not submit confidential prompts or private callback URLs unless the user trusts PoYo and the callback receiver.
• Do not make a live API call unless the user explicitly requests it and provides a safe server-side environment.

Required Capabilities and Permission Boundary

• Shell: run only the bundled scripts/submit_flux_schnell.sh helper after the user explicitly approves a live submission.
• Network: allow outbound HTTPS only to https://api.poyo.ai/api/generate/submit; use https://api.poyo.ai/api/generate/status/{task_id} only when the user asks to poll a returned task.
• Secret: read only POYO_API_KEY from the process environment and send it only in the PoYo Authorization header.
• Filesystem: read only the payload JSON file path explicitly supplied by the user. The helper does not write, delete, enumerate, or upload other local files.
• Do not broaden the endpoint, inspect unrelated environment variables, run background processes, or execute the helper automatically.

Execution

• Read references/api.md for endpoint details, request fields, example payload, response shape, and polling notes.
• Use scripts/submit_flux_schnell.sh only when the user wants to submit a reviewed JSON payload from a trusted shell.
• If the user only needs an example, adapt the one in references/api.md without making a live request.
• After submission, report the returned task_id clearly.

Output Expectations

When helping with FLUX Schnell, include:

• exact model id
• confirmation that the request is text-to-image
• final payload or concise parameter summary
• selected size, output count, and output format
• returned task_id if a request was submitted
• next step: poll status or wait for webhook
