Recommended read. Proactive agents are a whole new and underexplored category. This microharness is about having a persistent, always-on agent that's always thinking and doing important work.

Proactive agents are exciting because they unlock new ways to work with agents and unlock productivity.

My proactive harness has a similar functionality that stays running in the background, monitoring and tracking work across projects/tasks, and then, when it has a genuinely useful idea or suggestion, it activates. It learns my preferences as I interact with it over time, so it gets better at recommendations with every interaction.
