LSP

Language Server Protocol (LSP) is a standardized protocol for providing language services. By decoupling language services from CodeArts Agent CLI, LSP enables an independent language server process to deliver core capabilities such as code analysis, fast navigation, and symbol search.

CodeArts Agent CLI now features a built-in local LSP function. Once enabled, the agent can leverage these language services to provide code analysis, code navigation, and symbol information, enabling more accurate code comprehension and modification.
