## TL;DR

Tree-sitter parsers give code-intelligence systems fast, incremental syntax trees that can power highlighting, structural search, symbol extraction, and language-aware chunking.

## Core Explanation

Language models can read raw code text, but code agents need structural views too. A parser identifies declarations, calls, blocks, imports, comments, and literals so downstream tools can navigate source files without relying only on regexes.

Tree-sitter is especially useful in interactive and repository-scale settings because incremental parsing can update syntax trees after edits. It does not replace type checking or data-flow analysis, but it provides a stable syntax layer for many code-intelligence pipelines.
