get_lang_status

Return whether semantic (Phase B) analysis is available for the language of a given file, and an install hint when it is not. Use it to decide whether call-edge queries on a file will be backed by resolved semantic edges or only by Tree-sitter structural edges.

Input schema​

{
  "type": "object",
  "properties": {
    "file": {
      "type": "string",
      "description": "Repo-relative file path to detect language for"
    }
  },
  "required": ["file"],
  "additionalProperties": false
}

Output​

Returns a JSON object describing the detected language, whether Phase B is active, and how to enable it if not. Built-in languages (TypeScript/JavaScript, Rust, Python) report active without any install step; the rest report an install hint such as travsr lang install go.

When to use​

  • Before semantic queries: confirm that get_blast_radius with analysis: "semantic" or get_callers will use resolved call edges for this file's language.
  • Editor integrations: drive a one-click "install language tool" affordance when a file's language is recognized but Phase B is not yet active.

Notes​

  • Available over both stdio and SSE transports.
  • A language present in the repo but not registered in ~/.travsr/lang.toml reports as inactive with an install hint.
