The Agent Skills Directory

[SAFE]: The skill provides development templates and boilerplate code for the Model Context Protocol (MCP). It correctly identifies and uses the official SDKs: @modelcontextprotocol/sdk for Node.js and mcp for Python.
[SAFE]: Strong emphasis on security best practices is present throughout the instructions. It demonstrates the use of validation libraries like Zod and Pydantic to sanitize and validate inputs for tool calls, which is the primary defense against indirect prompt injection in MCP implementations.
[SAFE]: Secret management is handled correctly using environment variable placeholders (e.g., ${API_KEY}) in configuration examples, avoiding the risk of hardcoded credentials.
[SAFE]: All external dependencies and tools referenced (such as uv, npm, and npx @modelcontextprotocol/inspector) are standard, well-known developer utilities associated with the specified technology stack.
