Each tool serves a distinct purpose with clear boundaries: get_credits checks account balance, get_pricing retrieves product catalog, and place_order executes transactions. No functional overlap exists between the three operations.

All tools follow a consistent verb_noun snake_case convention. The naming clearly distinguishes between retrieval operations (get_) and the transactional operation (place_).

Three tools is minimal but reasonable for a focused ordering workflow. While the surface is thin, it covers the essential path from balance check to order completion without unnecessary bloat.

The toolset supports order creation but lacks order management capabilities such as status checking, order history retrieval, or cancellation. Once place_order is called, the agent has no visibility into order progress, creating a dead end for follow-up queries.
