Each tool has a distinct purpose: browsing catalog, purchasing, getting free content, searching, and verifying receipts. No overlap in functionality.
Most tools follow a verb-object pattern with hyphens, but 'get-free-content' and 'verify-receipt' omit the domain name 'spines-underground', causing slight inconsistency.
Five tools cover all essential operations for a digital catalog store: browse, search, get free content, buy, and verify payment. Neither too many nor too few.
The tool set covers the full lifecycle for this domain: discovering content (browse, search), accessing free content, purchasing paid content, and handling payment verification. No obvious gaps.
