Halo-record: Open-source audit trails for AI agents

Brian Kuan released halo-record, an open-source Python package that creates tamper-evident audit trails for AI agents by logging each tool call, model call, data access, and approval as an append-only line with a hash of the previous line. The package ensures that any edit to a record breaks the hash chain, making unauthorized changes detectable. The tool addresses the growing need for transparency and accountability in AI agent operations.

Each action becomes one line in a file that only ever gets appended to, and every line carries a hash of the line before it, a hash being a short fingerprint computed from content. Edit a record later and every fingerprint after it stops matching.
