Use this skill for Claude Sonnet 5 requests on PoYo. It helps agents prepare Claude-compatible Messages API payloads, streaming calls, tool definitions, structured output settings, and server-side integration notes.

Use When

• The user mentions Claude Sonnet 5, claude-sonnet-5, Claude Messages API, Claude-compatible messages, Claude tool use, or Claude structured output.
• The task is coding assistance, agent planning, long-form analysis, document summarization, multi-turn chat, tool planning, or vision prompt construction.
• The workflow needs a server-side curl example or a production Messages API payload for PoYo.

Model Selection

• claude-sonnet-5: use for Claude Sonnet 5 Messages API requests on PoYo.

Key Inputs

• model is required and should be claude-sonnet-5 for this skill.
• messages is required and should contain role and content.
• max_tokens controls response length.
• system sets assistant behavior and can be a string or supported content blocks.
• tools and tool_choice configure tool use when the application can execute tools.
• output_config can request structured output when supported.
• cache_control can mark reusable prompt content when supported.
• stream: true requires streaming-aware client handling.

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 user messages, system prompts, image content, tool inputs, or raw API key headers unless the user or product policy explicitly allows it.
• Do not make live API calls unless the user explicitly asks and provides a safe server-side environment.

Execution

• Read references/api.md for endpoint details, request fields, examples, and response notes.
• Use scripts/submit_claude_sonnet_5_messages.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.
• Claude Messages calls are synchronous unless streaming is enabled.

Output Expectations

When helping with Claude Sonnet 5, include:

• chosen model id
• final payload or concise parameter summary
• synchronous or streaming handling
• system prompt, tools, structured output, and cache settings when relevant
• response parsing notes if the user needs integration code
