[r/LocalLLaMA] Why AI Coding Agents Waste Half Their Context Window

Summary

An AI coding agent user observed that these agents frequently waste a significant portion of their context window. They spend 15-20 tool calls just to understand the codebase structure (e.g., grepping, reading files) before even beginning to write code. This inefficiency consumes a large chunk of their context, underscoring the critical importance of context position in agent performance.
