LedgerAgent: Structured State for Policy-Adherent Tool-Calling Agents

Customer service agents powered by language models must juggle multiple responsibilities simultaneously: tracking conversation state, calling external tools, and obeying domain-specific policies — all without losing their place. Current architectures bury all of this in a flat prompt, forcing the model to reconstruct context from scratch on every turn. LedgerAgent introduces a dedicated state ledger that keeps track of task facts explicitly and checks policy constraints before executing consequential actions. This has direct relevance for enterprise deployments where compliance errors carry legal or financial consequences, such as banking chatbots, insurance claim handlers, or healthcare scheduling assistants operating under strict procedural rules.
