Implementation Reference

• src/tool_handlers.ts:288-309 (handler)

  Main handler function for the w3_delegation_ls tool. Parses arguments using the schema, executes the 'delegation ls' command (with optional JSON flag), processes output using parseNdJson if JSON, and returns formatted content.

  const handleW3DelegationLs: ToolHandler = async (args) => {
    const parsed = Schemas.W3DelegationLsArgsSchema.safeParse(args);
    if (!parsed.success)
      throw new Error(
        `Invalid arguments for w3_delegation_ls: ${parsed.error.message}`
      );
    const { json } = parsed.data;
    const command = json ? "delegation ls --json" : "delegation ls";
    const { stdout } = await runW3Command(command);
    if (json) {
      const delegations = parseNdJson(stdout);
      return {
        content: [{ type: "text", text: JSON.stringify({ delegations }) }],
      };
    } else {
      return {
        content: [
          { type: "text", text: JSON.stringify({ output: stdout.trim() }) },
        ],
      };
    }
  };

• src/schemas.ts:127-133 (schema)

  Zod schema for input arguments of w3_delegation_ls, defining optional 'json' boolean flag defaulting to true.

  export const W3DelegationLsArgsSchema = z.object({
    json: z
      .boolean()
      .optional()
      .default(true)
      .describe("Format output as newline delimited JSON (default: true)."),
  });

• src/tool_handlers.ts:944-980 (registration)

  Registration of the w3_delegation_ls handler in the toolHandlers map, which is likely exported and used for tool registration in the MCP system.

  export const toolHandlers: Record<string, ToolHandler> = {
    w3_login: handleW3Login,
    w3_space_ls: handleW3SpaceLs,
    w3_space_use: handleW3SpaceUse,
