Yes. It lets the LLM immediately obtain precise information rather than having to reason across the entire source code of the code base (which ChatDBG also enables). For example (from the paper, Section 4.6):

  The second command, `definition`, prints the location and source
  code for the definition corresponding to the first occurrence of a symbol on a
  given line of code. For example, `definition polymorph.c:118` target prints the
  location and source for the declaration of target corresponding to its use on
  that line. The definition implementation
  leverages the `clangd` language server, which supports source code queries via
  JSON-RPC and Microsoft’s Language Server Protocol.
