Solid foundation with clear verb-based naming and consistent parameter descriptions. All 6 tools have documented schemas and descriptions. However, output schemas are not formally documented, responses are formatted strings rather than structured objects. Parameter descriptions lack constraint details (enums, ranges, formats). Error handling is present but minimal. No tool annotations (readOnlyHint, etc.). Descriptions average ~80 chars, below the 194-char baseline for A+ tools.

• Convert all tool responses from formatted strings to structured JSON objects. E.g., get_standings should return {standings: [{position, team_name, played, won, drawn, lost, goal_diff, points}, ...], competition, season} instead of a formatted table string.
• Add enum constraints to status parameters. Declare status as enum: ['FINISHED', 'SCHEDULED', 'LIVE'] in the schema. Add limit bounds (1 - 100) and season format (YYYY) to parameter descriptions.
• Add readOnlyHint: true to all tool schemas to signal idempotency and enable client-side caching and retry optimization.
• Implement structured error responses with error codes and recovery hints. E.g., {error: 'COMPETITION_NOT_FOUND', message: 'Unknown competition "xyz". Try: Premier League, La Liga, ...', retryable: false}.
• Add limit and offset parameters to get_matches and get_top_scorers. Return {results: [...], total_count, has_more} to enable pagination and prevent context window overflow.
