Use this skill for add-vocals jobs on PoYo. It helps agents prepare vocal-generation payloads for uploaded instrumental audio, submit async tasks, and explain callback or music detail retrieval.

Use When

• The user explicitly wants to use PoYo with Add Vocals, add-vocals, AI vocal generation, adding vocals to an instrumental, lyrics-to-vocals, or music production automation.
• The user asks for a PoYo Add Vocals request payload, server-side curl command, integration notes, callback setup, or music result retrieval.
• The user has already chosen PoYo as the execution provider for an instrumental-to-vocal workflow.

Model Selection

• add-vocals: use for generating vocals over an uploaded instrumental audio URL.

Key Inputs

• upload_url is required and must point to a publicly accessible instrumental audio file.
• prompt is required and can contain lyrics or a vocal direction.
• title is required and should be short enough for the documented title limit.
• style is required and should describe genre, mood, or vocal delivery.
• negative_tags is required and should describe vocal or music traits to avoid.
• mv is optional; documented values include V4_5PLUS, V5, and V5_5.
• vocal_gender, style_weight, weirdness_constraint, and audio_weight are optional controls when supported by the current PoYo docs.
• 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 log private audio URLs, lyrics, vocal prompts, generated audio URLs, callback URLs, task ids, or raw authorization headers unless the product policy allows it.
• Do not use this skill for generic music generation unless the user explicitly wants a PoYo Add Vocals API workflow.
• Do not make live API calls unless the user explicitly asks, confirms the payload should be sent to PoYo, and provides a safe server-side environment.

Execution

• Read references/api.md for endpoint details, request fields, examples, and result retrieval notes.
• Use scripts/submit_add_vocals.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 retrieval is easy.

Output Expectations

When helping with Add Vocals, include:

• chosen model id
• source instrumental URL handling notes
• prompt or lyrics summary
• style, negative tags, and optional vocal gender
• final payload or concise parameter summary
• returned task_id if a request was actually submitted
• next step: query music detail or wait for webhook
