Does this skill support both Python and TypeScript?

Yes, it provides specific implementation guides for Python (FastMCP) and Node/TypeScript SDKs, including project structure and validation patterns.

How does this skill help optimize LLM context usage?

It teaches agent-centric design, focusing on returning high-signal information and implementing configurable response levels (Concise vs. Detailed) to save tokens.

What is included in the implementation plan phase?

The implementation plan covers tool selection, shared utilities, input/output schema design using Pydantic or Zod, and robust error handling strategies.

Can I use this to test my custom tools?

Yes, the skill includes a comprehensive phase for creating an evaluation harness with realistic QA pairs to verify your tool's effectiveness before deployment.

What is an MCP server?

An MCP (Model Context Protocol) server is a standard that enables AI models like Claude to interact with external tools, local files, and APIs through a unified interface.
