What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of www.code402.dev controls every word below.
Simulate Spend Sentinel policy defense and escrow reversal
Simulate prompt-injection spend halts, hallucinated subagent delivery escrow reversals, and verified bounded spend under AP2 envelopes.
