The current agents´ modeling languages aim at representing the system and theirs agents in a clear way by diagrams, which permit shows theirs goals, plans and actions. Even with all provided by the language, some systems can´t be represented a correct form yet, because the current agents´ modeling languages represent only a whole system and not a product line. In this way the method proposed tries to determine a mapping of the flexibility points into software agents. The flexibility points into agents are defined to theirs plans and actions. Such points can be flexible if show a variability characteristic. The variability is presented by two points of view: the variability of plans and variability of action, where the variability of plans can enable many distinct plan for an agent, in other words, accept distinct applications for each one of theirs plans; and the variability of actions that enable the actions are executed in distinct form that result in distinct applications. With that, we can see an abstract actions and abstract plans will be inherited by the concrete actions and concrete plans, and that in the future will define new applications. For this the method uses the diagrams, tags and documentation. The documentation is used like a guide in a plan instance and action instance. After, these agents can generate the instance of new applications by yours owner plans and actions that´s determine the software product line and consequently it is possible to use the framework idea. With this approach it is possible to introduce into agent world all the advantage of frameworks and product lines, techniques that are traditionally used in object orientation. Moreover, the approach can be used concomitantly with current agents´ modeling languages. The benefits of the approach will be shown in more details through a case study.
