SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Tool design for agents is often inconsistent and hard to adopt; this skill provides a standardized approach to crafting tool descriptions, contracts, and usage guidance that helps agents select, use, and recover from errors effectively.

Core Features & Use Cases

  • Clear tool description structure with What, When, Inputs, Returns, and Errors.
  • Encourages consolidation of workflows into umbrella tools and consistent naming.
  • Use Case: When adding a new tool for an AI agent, generate a complete description and schema to minimize errors and improve reliability.

Quick Start

Example: Use the tool-design skill to generate a complete tool description for a hypothetical "Server:deploy_tool" tool, including parameters, returns, and error handling.

Frequently Asked Questions about tool-design

FAQPage Schema
How do I write consistent tool descriptions for AI agents?

Standardize tool descriptions for AI agents by using a consistent schema that defines What, When, Inputs, Returns, and Errors. This approach reduces tool-selection confusion and improves reliability by providing actionable error guidance for agent recovery.

What is the best way to structure MCP tool contracts?

Structure MCP tool contracts by enforcing a consistent schema that defines clear parameters, returns, and actionable error handling guidance. Consolidating workflows into umbrella tools with standardized naming further reduces tool-selection confusion for agents.

Why do agents select the wrong tools during task execution?

Agents select wrong tools due to inconsistent tool descriptions and naming conventions. Standardizing tool contracts and consolidating workflows into umbrella tools reduces selection confusion, ensuring agents select, use, and recover from errors effectively.

How do I generate a complete tool schema with error handling for agents?

Generate a complete tool schema by defining the tool description structure including parameters, returns, and actionable error guidance. This standardizes the tool contract, enabling agents to effectively use the tool and recover from execution errors.

Can I consolidate multiple agent workflows into a single umbrella tool?

Yes, you can consolidate multiple agent workflows into a single umbrella tool. This practice enforces consistent naming and schema standardization, which directly reduces tool-selection confusion and improves overall agent reliability across projects.

What should be included in agent tool error guidance?

Agent tool error guidance should include actionable recovery steps within the tool contract. Standardizing this error guidance alongside the What, When, Inputs, and Returns descriptions ensures agents can handle failures effectively and maintain reliability.
