PoYo Flux Kontext Image Generation and Editing#

Use this skill for Flux Kontext image jobs on PoYo. It helps agents prepare text-to-image and single-image editing payloads, choose Pro or Max model ids, submit async tasks, and explain polling or webhook follow-up.

Use When#

• The user explicitly mentions Flux Kontext, flux-kontext-pro, flux-kontext-pro-edit, flux-kontext-max, or flux-kontext-max-edit.
• The task is image generation, image editing, product visuals, reference-image edits, or output format control.
• The workflow needs PoYo async task submission, task status polling, or callback URL guidance.

Model Selection#

• flux-kontext-pro: use for Flux Kontext Pro text-to-image generation.
• flux-kontext-pro-edit: use for Flux Kontext Pro image editing with one source image.
• flux-kontext-max: use for Flux Kontext Max text-to-image generation.
• flux-kontext-max-edit: use for Flux Kontext Max image editing with one source image.

Key Inputs#

• prompt is required inside input.
• image_urls is required for edit models and only the first image is used according to current PoYo docs.
• size controls the documented output aspect ratio.
• output_format supports documented image formats.
• 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 ids, common fields, example payloads, and polling notes.
• Use scripts/submit_flux_kontext.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 Flux Kontext, include:

• chosen model id
• whether the request is generation or editing
• final payload or concise parameter summary
• selected size and output format when relevant
• whether a source image is involved
• returned task_id if a request was actually submitted
• next step: poll status or wait for webhook
