Implementation Reference

• src/server.ts:491-506 (registration)

  The close_surface tool is registered in src/server.ts, where it invokes client.closeSurface.

  // 9. close_surface
  server.tool(
    "close_surface",
    "Close a surface (terminal or browser pane)",
    {
      surface: z.string().describe("Target surface ref"),
      workspace: z.string().optional().describe("Target workspace ref"),
    },
    async (args) => {
      try {
        await client.closeSurface(args.surface, {
          workspace: args.workspace,
        });
        return ok({ surface: args.surface, applied: "close_surface" });
      } catch (e) {
        return err(e);

• src/cmux-client.ts:347-354 (handler)

  The actual implementation of closing a surface, which executes a cmux command.

  async closeSurface(
    surface: string,
    opts?: { workspace?: string },
  ): Promise<void> {
    const args = ["close-surface", "--surface", surface];
    if (opts?.workspace) args.push("--workspace", opts.workspace);
    await this.run(args);
  }
