Eve discovers capability identities from their paths. The component does not duplicate prompts, skills, tool definitions, or model history in Convex. It stores only the application thread/session binding and a sanitized projection of Eve's native message parts.

Approval-gated action

The demo's propose_training_plan tool uses Eve's always() approval policy. Eve pauses the durable run, while convex-eve projects the request into the host application and sends the authorized answer back to the exact waiting request.
