Scored across 19 tools
Most tools have distinct purposes: lessons explain concepts, while practical tools like read-this-challenge, how-do-i-pay, and verify-my-purchase handle specific actions. A few educational tools (e.g., what-is-x402 vs. read-this-challenge) could be confused, but descriptions clarify the difference.
Tool names are uniformly lowercase with hyphens, and most use an imperative verb or a 'what-is' pattern. The mix of verb phrases (get-a-wallet, verify-my-purchase) and noun phrases (what-is-usdc, what-is-acp) is slight but consistent enough to be predictable.
At 19 tools, the set is on the heavier side but appropriate for a curriculum covering 16 lessons plus practical helpers. Each tool represents a distinct lesson or action, so the count feels justified rather than bloated.
The tool surface covers the full learning path from wallet basics to advanced protocols like AP2 and ACP, plus practical utilities for decoding challenges, paying, verifying, and troubleshooting. Minor gaps like missing explicit lessons 3, 8, 9, and 10 are likely covered by the practical tools, so no dead ends.
