Grep beats LSP? Why coding agents ignore your fancier tools

I compared grep with LSP-backed semantic navigation across code-finding and editing tasks. The results show why a tool's LLM-friendliness may matter as much as the capability behind it. Why would a coding agent ignore a retrieval interface that returns more precise results? I explored this question in a small study comparing lexical search with grep against LSP-backed semantic navigation. I expect...
