    ### Authorization Actors

    These following actors and their sessions are coming from 
    the JWT authorization token, so you don't need to define them 
    in the request body schema.

    ${actors.map((a) => `- ${a}`).join("\n")}
  `;

  operations: AutoBeOpenApi.IOperation[],

  return StringUtil.trim`
    ### Path Parameters

    These following path parameters are defined for the operations,
    so you don't need to define them in the request body schema.

    ${operations
      .map((op) => [
        `- ${op.method.toUpperCase()} ${op.path}`,
        ...op.parameters.map((p) => `  - \`${p.name}\``),
      ])
      .flat()
      .join("\n")}
  `;
