AI Agent Tool Designer

Overview

This skill provides comprehensive guidance for designing tools that AI agents can use effectively. Whether building custom agent tools or any AI-accessible interfaces, these principles maximize agent success in accomplishing real-world tasks.

Note: Use the more specific mcp-builder skill if you want to create an MCP server.

The quality of a tool system is measured not by how comprehensively it implements features, but by how well it enables AI agents to accomplish realistic, complex tasks using only the tools provided.

Agent-Centric Design Principles

Before implementing any tool system, understand these foundational principles for designing tools that AI agents can use effectively:

1. Build for Workflows, Not Just API Endpoints

Principle: Design thoughtful, high-impact workflow tools rather than simply wrapping existing API endpoints.
