Agent Custody, a paper trail for AI agent actions
A gateway and verification system that turns AI-agent tool calls into signed receipts, linking authorization, inputs, outcomes, and downstream beliefs.
Field notes
The system separates evidence about actions from state about beliefs. Its Receipts package records tool name, arguments, outcome, policy decision, and grant, while State maintains a fact ledger whose entries cite those receipts. The page lists JSONL, SQLite, and Postgres as ledger options and names Mem0 and Zep adapters for recall. It also distinguishes fields that are attested, observed, or merely claimed, a useful limitation for anyone evaluating agent audit trails.
