Implementation Reference
- src/index.ts:230-237 (handler)Tool handler for 'tanstack_doc'. Builds CLI args from library, path, and optional docsVersion, then runs the CLI and returns JSON-parsed result.
async ({ library, path, docsVersion }) => { const args = ["doc", library, path, "--json"]; if (docsVersion) args.push("--docs-version", docsVersion); const { stdout } = await runCli(args); return jsonResult(parseJsonOutput(stdout)); }, ); - src/index.ts:214-229 (schema)Schema definition for 'tanstack_doc'. Defines description and input parameters: library (string), path (string), docsVersion (optional string).
