How does it improve agent reliability?

By implementing explicit error handling and input validation patterns, the skill helps agents recover from failures instead of looping or hallucinating.

Why are tool descriptions more important than implementation?

An LLM never sees your source code; it only sees the schema and description. Clear documentation ensures the LLM understands when and how to trigger the tool correctly.

What is the Agent Tool Builder skill?

It is a specialized set of guidelines and patterns for designing high-performance tools and function calls that allow AI agents to interact reliably with the outside world.

Can this skill help reduce API costs?

Yes, well-designed tools prevent the LLM from making redundant calls or using excessive tokens to figure out how a vague tool works.

Does this skill support the Model Context Protocol (MCP)?

Yes, it provides guidance on using the MCP standard, which is becoming the universal language for connecting AI models to data and tools.

Designs robust tool schemas and descriptions that optimize LLM performance and minimize model hallucinations.

概要

Agent Tool Builder is a specialized skill for crafting the interfaces through which AI agents interact with external systems. It emphasizes the critical importance of JSON Schema design, crystal-clear tool descriptions, and the emerging Model Context Protocol (MCP) standard. By focusing on how an LLM perceives a tool rather than just its back-end implementation, this skill helps developers build reliable agents that handle errors gracefully, avoid silent failures, and operate with maximum token efficiency.
