An AI agent design that refuses to act on what it merely assumes
Short summary
LedgerAgent enforces two safeguards: agents must verify state changes before trusting them (observe-not-assume rule), and consequential actions must pass policy gates before execution. This prevents agents from falsely narrating outcomes they never verified, making them reliable for high-stakes tasks like refund processing. The tradeoff is latency from extra verification reads, but this safety discipline is essential for operations where confidence in false beliefs becomes confidence in false deeds.
- •Agents must verify state changes before trusting them (observe-not-assume rule)
- •Consequential actions are gated against policies before execution, not after
- •Adds latency but prevents costly failures in high-stakes operations like refunds
Generated with AI, which can make mistakes.
