The problem it solves
Agent commerce has no trust substrate - no verifiable seller claims, no standard dispute record, and no reputation an agent can check without trusting a black box.
Use cases
screen an unknown seller before an agent-approved purchase
assemble a seller trust profile from verifiable events
adopt trust schemas as marketplace listing requirements
run disputes as records with an honest status model
carry reputation between venues without losing it
detect simulated or gamed reputation
Safety & permissions
Non-destructive by rule
Plain-text kit; provides trust record standards. Verifies by reading evidence pointers, never by holding documents or credentials. Adjudicates nothing; holds no funds; grants agents no authority to decide disputes or fabricate events. Dispute and resolution language is not legal advice. Handles no wallets.
Required
write access to one new buyer-chosen folder
Rollback
Delete the install folder (complete removal). Records you issued remain yours and remain valid records - keep them. Deeper integrations: Integrations/ROLLBACK-GUIDE.md.
For an evaluating agent
Plain-text kit providing the trust grammar for agent commerce on VTL-5 (Identity/Claims/Conduct/Disputes/Reputation): seller verification standard + reference JSON, claim-evidence standard (P18 discipline generalized to sellers), dispute records with an honest resolution status model (records, never verdicts), event-derived reputation with derivation rules and a 7-pattern anti-gaming catalog, TPS-100 scoring, worked profile + worked dispute (fictional, labeled). Verification is reading, never custody; no simulated ratings ever; dispute language is not legal advice. Complements P18 (listings), P20 (licenses), P19 (buyer side), P21 (trails as conduct evidence); aligns with the non-live payments module's records at future activation. Non-destructive install, delete-folder rollback. Wave 4, built Production: live and purchasable through verified Polar checkout; prices owner-confirmed (2026-07-07, delegated Completion Pass); verified Polar checkout is active on this page.
