A3.8/5.0

Scored across 3 tools

Disambiguation4/5

The three tools have clearly separable roles: feedback is for reporting issues to humans, x402_pick is the free preview/discovery call, and x402_buy is the paid execution call. The pick/buy pair shares a lot of description text and could momentarily blur, but the free-vs-paid distinction is stated explicitly in both.

Naming Consistency4/5

x402_pick and x402_buy form a clean prefix+verb pattern that makes the pair obvious. feedback breaks the convention (bare noun, no prefix), a minor deviation in an otherwise tiny and readable set.

Tool Count4/5

Three tools is lean but each earns its place: one discovery call, one paid execution call, one human feedback channel. No filler tools, though the surface is small enough that some adjacent capabilities (history, receipts) are absent rather than consolidated.

Completeness3/5

The core lifecycle (preview what will be bought, buy it, report problems) is covered, but there is no way to retrieve past purchases or receipts, check wallet/balance state, or browse sellers without specifying a need. Agents that want to verify or audit a prior transaction hit a dead end.
