What problem does it solve?
This Skill eliminates the friction of building or debugging LLM APIs that work across multiple providers, removing vendor lock-in and inconsistent implementation gaps for teams working with 600+ AI models.
Core Features & Use Cases
- Full Specification Reference: Covers the complete Open Responses standard including HTTP protocol structure, polymorphic item systems, state machines, SSE streaming, tool architecture, agentic loops, and extension frameworks.
- Implementation & Debugging Guidance: Provides compliance checklists, error handling rules, concrete streaming sequence examples, and tool call orchestration patterns for building compliant servers and clients.
- Use Case: Use this Skill to implement a /v1/responses endpoint that supports parallel tool calls, debug streaming event ordering issues, or extend the spec with custom provider-specific item types without breaking client compatibility.
Quick Start
Use the open-responses skill to build a compliant POST /v1/responses endpoint that supports streaming text responses and parallel function tool calls.
