Implementation Reference

• src/tool_handlers.ts:70-89 (handler)

  The handler function that executes the w3_space_use tool. It validates input arguments using the schema, runs the 'w3 space use' command with the provided spaceDid, and returns a JSON-formatted response with success message and command output.

  const handleW3SpaceUse: ToolHandler = async (args) => {
    const parsed = Schemas.W3SpaceUseArgsSchema.safeParse(args);
    if (!parsed.success)
      throw new Error(
        `Invalid arguments for w3_space_use: ${parsed.error.message}`
      );
    const { spaceDid } = parsed.data;
    const { stdout } = await runW3Command(`space use ${spaceDid}`);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({
            message: `Successfully set current space to ${spaceDid}`,
            output: stdout.trim(),
          }),
        },
      ],
    };
  };

• src/schemas.ts:11-16 (schema)

  Zod schema for the input arguments of the w3_space_use tool, defining 'spaceDid' as a required string that must start with 'did:key:'.

  export const W3SpaceUseArgsSchema = z.object({
    spaceDid: z
      .string()
      .startsWith("did:key:")
      .describe("The DID of the space to select (e.g., did:key:...)."),
  });

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

  The toolHandlers object maps tool names to their handler functions, registering 'w3_space_use' to handleW3SpaceUse. This object is imported and used in index.ts for dynamic tool execution.

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