Optimizes agent-tool interfaces through consolidation principles, architectural reduction, and precise Model Context Protocol standards.

This skill provides a framework for designing robust tools that agents can reliably interpret and execute. It addresses the fundamental gap between deterministic APIs and non-deterministic agents by treating tool definitions as a form of prompt engineering. By implementing the consolidation principle and architectural reduction, this skill helps developers move away from brittle, specialized tools toward lean, primitive-based systems that leverage an agent's reasoning capabilities. It is essential for anyone building production-grade agentic workflows, debugging tool-selection failures, or implementing Model Context Protocol (MCP) integrations.
