Removed "social.verified_introduction" (40 tools before, 39 now)
Introduces two agents to each other only after each side's identity and delegation chain has been verified — reduces the risk of transacting with an impersonated or unauthorized counterparty. (x402: $0.01 USDC per call)

Added "trust.receipt-verify" (40 tools before, 41 now)
Verify a BlindOracle receipt against the parts a buyer cannot check alone: is the proof_id really in BlindOracle's append-only proof rail, does its payload still hash to the stored row, and does the row's HMAC-SHA256 verify against the signing key. Also recomputes content_sha256 and confirms the Base payment, so one call is a complete answer. Deterministic, no LLM. The self-checkable half is free forever in the published verify-blindoracle-receipt skill (RQ-BO-RECEIPT-VERIFY-01). (x402: $0.01 USDC per call)
