SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps in designing, refining, and consolidating agent tools to improve their clarity, efficiency, and effectiveness in agent systems.

Core Features & Use Cases

  • Tool Design Principles: Learn best practices for creating tools that language models can easily understand and utilize.
  • Consolidation: Guidance on merging multiple narrow tools into more comprehensive ones to reduce ambiguity.
  • Description Engineering: Crafting effective tool descriptions that act as prompts for agents.
  • Use Case: You are building a new agent and need to define its interaction with external systems. This skill will guide you on how to design the tools for optimal agent performance.

Quick Start

Use the tool-design skill to learn how to create effective descriptions for agent tools.

Frequently Asked Questions about tool-design

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design agent tools that language models can understand and use correctly?▼

Designing agent tools requires crafting clear tool contracts and prompt-like descriptions so the model understands the tool's purpose. This skill provides guidance on consolidation and effective description engineering to reduce ambiguity and improve agent performance.

What is the best way to consolidate multiple narrow agent tools into fewer comprehensive ones?▼

Consolidating agent tools involves merging narrow functions into broader tools to reduce ambiguity and architectural overhead. This skill guides you through consolidation principles that optimize tool sets for better agent decision-making and fewer misuse errors.

Why does my language model agent misuse tools or call the wrong API?▼

Agent tool misuse often stems from unclear tool descriptions or overly complex tool sets. This skill helps debug misuse by refining description engineering, improving error messages, and consolidating tools to ensure the agent selects the correct function.

Do I need to write prompt-like descriptions for MCP tools and API integrations?▼

Yes, writing prompt-like descriptions for MCP tools and API integrations is essential for effective agent performance. This skill guides you in treating tool descriptions as prompts, ensuring clear contracts and efficient error message design for external systems.

Can I use this approach to optimize existing tool sets without building new agent tools?▼

You can optimize existing tool sets by applying architectural reduction and description engineering principles. This skill addresses scenarios for refining and consolidating tools you already have, improving clarity and efficiency without needing to build new ones.

What are the limitations of consolidating agent tools into broader functions?▼

Consolidating agent tools can reduce flexibility for highly specific tasks and requires careful description engineering to avoid confusing the model. This skill helps determine when merging tools is beneficial and when keeping them separate is necessary for optimal agent performance.
