Scored across 5 tools
Disambiguation4/5
buy_vpn, sign_and_pay, and fulfill_payment all touch payment/fulfillment, so an agent could confuse them; however descriptions explicitly mark buy_vpn as preferred, sign_and_pay as debug-only, and fulfill_payment as recovery-only. wallet_status and list_vpn_catalog are clearly distinct read-only tools.
Naming Consistency4/5
All names use snake_case, and most follow a verb_noun pattern (list_vpn_catalog, sign_and_pay, buy_vpn, fulfill_payment); wallet_status is a noun phrase without a verb. The deviation is minor and still readable.
Tool Count5/5
Five tools map cleanly to wallet check, catalog discovery, purchase, debug payment, and recovery, with no obvious extraneous tool. The scope is narrow enough that five is well-scoped.
Completeness3/5
The core purchase flow is covered, but there is no tool to retrieve previously saved VPN credentials or list past purchases, despite buy_vpn saying it saves credentials. No refund/cancel or balance check exists either, so later-session workflows can hit dead ends.
