SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Tools are often poorly described, leading to inconsistent tool behavior, ambiguous activations, and brittle agent routing. This skill provides a principled approach to tool interface design, ensuring clear contracts, consistent naming, and actionable error handling across tool catalogs.

Core Features & Use Cases

  • Establishes a consistent, explicit tool-description framework that captures purpose, activation triggers, parameters, return formats, and error handling.
  • Enables consolidation and scalable tool collections by guiding when to combine or split tools to reduce ambiguity.
  • Use cases include designing new tools for agent catalogs, auditing existing tools for clarity, and mentoring teams on standard tool schemas.

Quick Start

Craft a complete tool schema for a hypothetical new tool named weather_fetch, following the described structure.
