Hooks that force Claude Code to use LSP instead of Grep for code navigation. Saves ~80% tokens

Saving tokens with Claude Code. Tested for a week. Works 100%. The whole thing is genuinely simple: swap Grep-based file search for LSP. Breaking down what that even means LSP (Language Server Protocol) is the tech your IDE uses for "Go to Definition" and "Find References" - exact answers instead of text search. The problem: Claude Code searches through code via Grep. Finds 20+ matches, then reads 3-5 files essentially at random. Every extra file = 1,500-2,500 tokens of context gone. LSP returns a precise answer in ~600 tokens instead of ~6,500.
