Why Your Coding Agent Needs More Than Grep: LSP, Semantic Search, and the Rise of the CLI

Coding agents are getting smarter, but they still waste most of their tokens reading irrelevant code. Here is how AST-based semantic search, LSP, and a lightweight CLI can change that. We built an embedded lightweight semantic code search tool for coding agents that is complementary to LSP and this is what we’ve learned. compare The Problem: Coding Agents Are Flying Blind If you have used Claude Code, Cursor, Codex, or any AI coding agent recently, you have probably noticed something: these tools spend a lot of time and tokens just trying to understand your codebase.
