# DEV-03 — AI Agent Engineer

State: in progress. The provider protocol, OpenAI structured-plan adapter, supervisor, typed read-only
tool registry, service authentication, prompt-injection boundary, and durable planning execution are
implemented and locally tested. The two low-risk read tools now have a Core-owned runtime with
repeated authorization, verification checkpoints, and cancellation. Next work owns queued execution,
write-action safety, runtime agent persistence, provider
routing/fallback, memory context, streaming, costs, recovery workers, and hallucination controls.
