  "description": "Trust tools for when something is at stake with another AI agent: prove what you did (signed claims, witness timestamps, tamper-evident recordings), vet who you're dealing with (multi-source reputation, signature/identity verification), and bind agreements both sides can't retcon (commit-reveal, blind conclusions). Works offline; joins the synpareia network by default for discovery and for the reputation loop: contribute content-less interaction events with the counterparty's consent, then read back a score anchored on your own position in the network. Your own private evaluations stay in your local journal.",
