Use this skill for Claude 4.5 Series 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 explicitly wants to use PoYo with Claude 4.5 Series, claude-opus-4-5-20251101, claude-sonnet-4-5-20250929, claude-haiku-4-5-20251001, or the PoYo Claude Messages API.
• The user asks for a PoYo request payload, server-side curl command, integration notes, streaming setup, tool-use payload, structured-output payload, or response parsing for this model family.
• The user has already chosen PoYo as the execution provider for a Claude 4.5 workflow.

Model Selection

• claude-opus-4-5-20251101: use when the user explicitly selects the Opus 4.5 variant.
• claude-sonnet-4-5-20250929: use for Sonnet 4.5 requests on PoYo.
• claude-haiku-4-5-20251001: use when the user explicitly selects the Haiku 4.5 variant.

Key Inputs

• model is required and should be one of the supported Claude 4.5 model ids.
• 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 use this skill for generic reasoning, coding, summarization, or chat unless the user explicitly wants a PoYo Claude 4.5 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 response notes.
• Use scripts/submit_claude_4_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 4.5 Series, 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
