A community of interacting software agents can support an activity of human agents. We describe an experiment based on an existing information server showing how software agents compete for the attention of the user with the intention to support her in an information-rich task through providing her some useful comment. To be successful in the competition, agents have to capture contextual parameters about the current activity of the user and render them in a context-sensitive annotation to information. The outcome of the competition for attention consists of a weighted topic structure, annotated with text templates. The annotated topic structure is the basis for generating a context-sensitive navigation node by a process of template expansion and aggregation.
