Skill: OpenAI Agent Tools

Purpose

Define reusable function tools for OpenAI Agents using the OpenAI Agents SDK function_tool interface.

These tools expose external capabilities (RAG, databases, selection-based answering) to the agent without embedding reasoning logic.

Responsibilities

• Define tools using @function_tool
• Enforce strict input/output contracts
• Provide deterministic, side-effect-aware behavior
• Support Retrieval-Augmented Generation (RAG)

What This Skill Covers

• function_tool decorator usage
• Tool input schema design
• Tool output structure
• Tool naming conventions

What This Skill Does NOT Cover

• Agent reasoning or planning
• Prompt engineering
• UI concerns

Constraints

• Tools must not call LLMs
• Tools must not hallucinate
• Tools must return factual data only

Used By

• openai_agent_runtime
• RAG Orchestrator Agent
