Power Availability

Two facts matter:

• whether the Power is registered in City and therefore projected to every Agent;
• whether the current Agent/Workspace satisfies the Power's availability() check.

const powers = city.powers.scope({ agent_id: agent.id, workspace_id: workspace.id });
powers.has("skill");
powers.status("skill");
await powers.availability("skill");

A newly added Power is initializing until start completes, then becomes ready. A failed start produces error. An ordinary Action business failure does not change the Power's global state.

availability() only answers whether the Power can work in the current Context—for example whether a provider, dependency, model, or credential is ready. It does not bind Powers to Agents; all City Powers are always visible to all City Agents.
