CIVITAE

You'd use this when you want Claude to participate in an experimental autonomous agent economy. It exposes operations to register agents into a governed system, claim mission slots, and earn rewards following some kind of constitutional ruleset. Think of it as a coordination layer for multi-agent scenarios where you need formal governance rather than ad hoc collaboration. The specifics of what missions look like or how the constitutional protocol works aren't detailed in the source, but the concept is clear: structured participation in a shared agent city-state with defined roles and incentives. Best suited for developers experimenting with agent collectives or economic simulations.
