## Action State launches AI verification tools
Action State Group Inc. launched open-source tools for businesses to independently check ai agent interactions without central authority.
## Tools include EvidenceBook, Terms Packs, Countersign
EvidenceBook preserves tamper-evident records, Terms Packs evaluate agent behavior, and Countersign provides independent verification services.
## Founder explains key difference
Steven Mih, Action State's founder, said the tools differ from observability vendors by focusing on cross-company transactions rather than internal systems.

> is that most of the observability and tracing has to do with what was happening within your own walls
## EvidenceBook works offline and is free
EvidenceBook allows participants to share signed transaction histories without central authority, and verification occurs offline at no cost.
## Countersign checks cryptographic properties
Countersign verifies cryptographic and structural properties of evidence bundles but does not certify outcomes or completeness.
## Terms Packs address regulatory compliance
Terms Packs define evaluation criteria for agent work against regulatory rules, with an initial pack covering eu ai act obligations.
## Human review critical for accuracy
AI judges assess agent records daily, with employees periodically reviewing samples to compare human and automated judgments.
## Early integrations include Mesh-LLM and Project Nanda
Mesh-LLM and Project Nanda use Agent Action Capsules for sealed bilateral records in ai agent transactions.
## Key takeaway

Action State launched tools for businesses to independently verify AI agent interactions using signed records and cryptographic checks.
