Quick Review

Exceptional MCP server development skill with comprehensive, well-structured guidance. The SKILL.md provides clear phase-based workflow (research, implementation, review, evaluation) with explicit instructions a CLI agent can follow. Task knowledge is excellent - covers agent-centric design principles, API integration, framework-specific implementations, and evaluation creation. Structure is exemplary: concise overview with logical phases and detailed references externalized to separate files. Novelty is strong - building production-quality MCP servers with proper agent design patterns, evaluation harnesses, and multi-language support would require significant token investment for a CLI agent alone. Minor improvement possible in making some external fetch requirements more explicit upfront, but overall this is a highly useful, well-designed skill that meaningfully reduces complexity and cost for a specialized domain.
