⚡️ Coding agents reach for grep. Not LSP. Every time.
Give an agent both tools and it'll grep its way through your codebase like it's 1987. LSP just... sits there.
Likely reason: grep is all over training data. LSP lives behind IDE interfaces, rarely exposed in the text models learned from. So agents default to what they know.
It works. But it's a ceiling. Source

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.
