LSP

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

CodeArts Agent 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.

Constraints

This function can be used only in agent mode.
