LedgerAgent: Structured State to Keep Tool-Calling Agents Policy-Adherent

arXiv·low signal

LedgerAgent (arXiv 2606.20529, June 20) maintains an explicit structured 'ledger' of state to stop tool-calling agents from drifting out of policy over long interactions — a recurring production failure where agents quietly stop following rules across many tool calls. It's a concrete pattern for policy-constrained domains (finance, compliance, ops) where free-form context isn't enough to enforce invariants. Useful if you're hardening reliability of an agent that takes consequential actions.
