Two tools with basic definitions but significant gaps in parameter documentation, output schemas, and error handling. Tool names follow verb_noun convention (good), but descriptions lack the depth needed for reliable LLM selection. No input validation, no pagination support, no structured output documentation, and no error recovery guidance. Schema definitions are minimal, parameters are typed but lack descriptions. The server returns plain strings rather than structured objects, forcing the LLM to parse unstructured text.

• Convert string returns to structured JSON. live_scores should return {"matches": [{"home_team": string, "away_team": string, "home_goals": int, "away_goals": int, "minute": int, "league": string}], "total": int}. standings should return {"teams": [{"rank": int, "name": string, "points": int, "played": int}], "league_id": int, "season": int, "total": int}.
• Add explicit descriptions to all parameters. For standings: league_id should read 'The football league ID (e.g. 39=Premier League, 140=La Liga, 61=Ligue 1). Call discover_leagues() to find valid IDs.' season should read 'The season year as a 4-digit integer (e.g. 2024). Typically the year the season started.'
• Implement pagination in standings. Add optional parameters: limit (1 - 100, default 20) and offset (default 0). Return total count so the LLM knows if more results exist.
• Add explicit error handling. Return JSON error objects with category (invalid_input, api_error, rate_limit, not_found) and recovery hint. E.g. {"error": "invalid_league_id", "message": "League ID 999 not found. Valid IDs: 39, 140, 61, ...", "recovery": "Check league_id spelling or call discover_leagues()."}
• Add a discover_leagues() tool that returns available league IDs, names, and countries. This enables self-service discovery without hardcoding examples in descriptions.
• Validate RAPIDAPI_KEY at server startup. If missing, raise a clear error: 'RAPIDAPI_KEY environment variable not set. Set it before running the server.'
• Add timeouts to HTTP calls (e.g. timeout=10s). Return a timeout error if the API does not respond within 10 seconds, with guidance to retry.
