We discuss some features of the new logic programming language DALI for agents and multi-agent systems, also in connection to the issues raised in [12]. We focus in particular on the treatment of proactivity, which is based on the novel mechanism of the internal events and goals. As a case-study, we discuss the design and implementation of an agent capable to perform simple forms of planning. We demonstrate how it is possible in DALI to perform STRIPS-like planning without implementing a meta-interpreter. In fact a DALI agent, which is capable of complex proactive behavior, can build step-by-step her plan by proactively checking for goals and possible actions.
