## Executive Summary
In this post, we show where MCP tool design goes wrong and how to fix it with practical context engineering approaches.

## Why It Matters (Strategic Analysis)
Crucially, this shifts the paradigm of agentic system optimization away from raw model scaling toward disciplined context engineering. As a result, developers must redesign API exposures to prevent token exhaustion and reasoning failures.
