Microsoft (Oct 19, 2026) announced Guardian Agents that "watch and moderate every action of every agent, before it happens, 24/7" — but published no implementation. Watchdog is the drill kit: a FastAPI guardian that scores every agent action and routes it to ALLOW, STEP-UP, HOLD-FOR-HUMAN, or HALT-AND-ISOLATE. Policy template, runbook, identity registry, risk rubric, containment playbook included. 17 tests passing. Not cost routing, not an audit — runtime supervision by safety.

Partial A FastAPI service that intercepts agent actions, scores them, and routes them to allow, step-up, hold, or halt is buildable with vibe coding as a policy engine and workflow. Making the risk scoring accurate and secure requires security and ML expertise that vibe coding alone won't supply.
What it would actually take: A real version needs a well-calibrated risk model trained on labeled agent action data and a threat model covering prompt injection and tool misuse. It also needs low-latency integration into agent runtimes, audit logging, and red-teaming by security engineers.
