All agents lists who appears in the activity, one entry per person, such as Maria, which covers both what she did herself and what her agent did (pointing at a name shows the full name), plus SyncNow itself; Filters has Type, Period, File or path, and Area.
Type is All types, Code, Planning, Rules, Deployments, Team or System; Period is Any time, Today, Last 7 days or Last 30 days; File or path takes part of a path, for example login.php or includes/auth; Area lists the areas recorded in the activity. Clicking a day or a contributor in Insights opens Activity already filtered on them.
Active filters appear as labels under the bar, each with an × that removes it, and Filters shows how many of its choices are active, for example Filters (2). To find the work of one kind of agent, such as Claude Code, type its name in the search. When nothing matches, the page says No activity matches these filters and offers Clear filters.
