tool-definition

What problem does it solve?

This Skill provides a repeatable pattern for defining Claude Code Tools with a schema-first approach, ensuring validation, permissions, and safe defaults are baked in from the start.

Core Features & Use Cases

• Schema-first design using Zod to define inputs and ensure runtime validation and TypeScript types stay in sync.
• Safe tool composition with buildTool factory, default flags, and a centralized permission check that runs before execution.
• Use cases include adding new tools or updating existing tool behavior while maintaining security, reliability, and consistency across the Code environment.

Quick Start

Implement a new tool by calling buildTool with the appropriate inputSchema, permission checks, and default configurations.
