Four well-named tools with clear, actionable descriptions (avg 180 chars). All tools have complete input schemas with typed parameters and descriptions. Tool names follow verb_noun pattern (search_, get_, find_). Descriptions include examples and explain prerequisites (e.g., 'Use the game ID from search_games'). However, output schemas are not documented, LLMs cannot predict response structure for downstream chaining. Error handling returns generic messages without recovery guidance. No parameter constraints (enums, ranges) despite opportunities (e.g., 'max' and 'top' lack bounds). Missing idempotency hints and destructive operation markers.

• Document output schemas for all tools. Example for search_games: 'Returns {count: number, games: [{id: string, name: string, abbreviation: string, released: number|null, weblink: string}]}'. This enables LLMs to chain tools and extract fields correctly.
• Add numeric constraints to 'max' and 'top' parameters. E.g., 'Maximum number of games to return (1 - 100, default 10)'. Prevents LLMs from passing invalid values.
• Enhance error messages with recovery guidance. Instead of 'Speedrun.com search_games error: 404', return 'Game not found. Try a different query or use search_games with a partial name (e.g., "mario" instead of "super mario 64").'
• Move '_apiKey' from tool parameters to server-side environment variable (SPEEDRUN_API_KEY). Remove from all tool schemas. Prevents credential leakage in logs and traces.
• Add tool annotations to schema. Mark all four tools with 'readOnlyHint: true' and 'idempotentHint: true' to enable client-side caching and safe retry logic.
