Each tool has a clearly distinct purpose: get_card_info retrieves details for a specific card ID, parse_deck_code processes deck codes to return deck information, and search_cards searches by card name. There is no overlap in functionality, making it easy for an agent to select the correct tool without confusion.

All tool names follow a consistent verb_noun pattern (get_card_info, parse_deck_code, search_cards), using snake_case throughout. This predictability enhances readability and usability for agents, with no deviations in naming style.

With only 3 tools, the server feels thin for a domain like Hearthstone decks, which might involve more operations such as creating, updating, or managing decks. While the tools cover basic retrieval and parsing, the count is borderline for the apparent scope, potentially limiting agent capabilities.

The tool set is significantly incomplete for a Hearthstone deck management domain. It lacks essential CRUD operations like creating, updating, or deleting decks, and does not cover lifecycle aspects such as deck validation or sharing. Agents will face dead ends when trying to perform common deck-related tasks beyond basic lookup and parsing.
