Three tools with clear verb-noun naming (search_game, get_game, get_game_reviews) and solid descriptions (120-180 chars each). All tools have input schemas with typed parameters and descriptions. However, output schemas are not documented in the source, LLMs cannot see what fields to expect from responses. Parameter descriptions lack format constraints (e.g., 'platform' accepts free-form strings with only examples 'PC', 'PS5', 'Xbox', 'Switch' in the description, not an enum). No error handling guidance visible. Tool descriptions mention optional filtering but don't explain what happens if a platform filter matches nothing. Missing documentation of response structure, pagination behavior, and error cases.

• Document output schemas for all three tools. For search_game, specify: returns array of {id: number, name: string, dist: number}. For get_game, specify all fields and their types (e.g., topCriticScore: number|null, percentRecommended: number|null, platforms: array of {id, name, shortName}).
• Convert 'platform' parameter to an enum in get_game and get_game_reviews. Extract valid platform names from the OpenCritic API (e.g., 'PC', 'PS5', 'Xbox Series X', 'Nintendo Switch') and declare them as enum values in the schema.
• Add error handling guidance to tool descriptions. E.g., 'If no results found, try a shorter or different game title.' 'If platform filter returns no reviews, the game may not be available on that platform.'
• Specify pagination behavior for search_game. Does it always return ≤10 results? Can the LLM request more? If not, state: 'Returns up to 10 results; no pagination available.'
• Document which fields in get_game response are always present vs optional (e.g., mediumImage and squaredImage may be null; genres and platforms may be empty arrays).
