SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the process of designing and integrating tools, ensuring they are secure, efficient, and well-defined, preventing potential security risks and improving overall system robustness.

Core Features & Use Cases

Secure Tool Integration: Design interfaces for MCP servers, HTTP endpoints, and CLI tools with a focus on least privilege and auditable contracts.
Task-Shaped Contracts: Define clear, purpose-driven contracts for tools, moving beyond raw API mirroring to ensure focused functionality.
Use Case: When introducing a new API for customer data retrieval, use this Skill to define a narrow, auditable fetch_customer_invoice tool instead of a broad GET /customers/{id} endpoint, specifying necessary authentication and access controls.

Quick Start

Use the tool-design skill to define a task contract for a new tool that fetches user profiles.

FAQPage Schema

How do I design secure tool contracts for MCP servers?▼

Designing secure MCP server tool contracts involves defining task-shaped interfaces that enforce least privilege, authorization, and auditable actions rather than mirroring raw API endpoints directly.

What is the best way to define task-shaped contracts for HTTP endpoints?▼

The best way to define task-shaped contracts for HTTP endpoints is to create narrow, purpose-driven interfaces—like a specific fetch action—instead of broad API mirrors, ensuring focused functionality and security.

How do I enforce least privilege and authorization for CLI tool integrations?▼

Enforce least privilege and authorization for CLI tool integrations by selecting appropriate authentication methods, defining clear integration boundaries, and specifying auditable task contracts that limit access strictly to necessary actions.

When do I need to specify auditability and approvals for API design?▼

You need to specify auditability and approvals in API design when introducing tools that handle sensitive data, ensuring that all task-shaped contracts define strict access controls and trackable execution logs.

Can I use this approach to modify existing tool integrations and boundaries?▼

Yes, you can modify existing tool integrations by redefining their interface boundaries, selecting appropriate transport mechanisms, and updating their task contracts to enforce better security and auditable execution.

Why use task-shaped tool contracts instead of raw API mirroring?▼

Task-shaped tool contracts prevent security risks by enforcing least privilege and auditable actions, whereas raw API mirroring often exposes overly broad endpoints without proper authorization or focused functionality.
