Three tools with basic schemas and descriptions, but significant gaps in parameter documentation and output structure. Tool names follow verb_noun convention (get_alerts, get_forecast, hello). Descriptions exist but are minimal (10-60 chars, below the 50-200 char LLM-optimized baseline). Input schemas present with type info but lack parameter descriptions for critical fields like 'state' and 'latitude'/'longitude'. No output schemas documented. Error handling returns plain strings with no recovery guidance. No tool annotations (readOnlyHint, etc.). Composition is reasonable, each tool has one responsibility, but parameter naming could be more explicit (e.g., 'state' should clarify it expects a two-letter US state code, not a full state name).

• Expand tool descriptions to 80-150 chars. Example: 'Get active weather alerts for a US state. Returns event type, severity, area, and instructions. Call this to check for warnings before get_forecast.'
• Add parameter descriptions with constraints. For 'state': 'Two-letter US state code (e.g., CA, NY, TX). Must be uppercase.' For 'latitude'/'longitude': 'Decimal degrees, range -90 to 90 (latitude) and -180 to 180 (longitude).'
• Document output schemas. E.g., get_alerts returns {alerts: [{event: string, area: string, severity: string, description: string}], count: number}.
• Enhance error messages with recovery hints. Instead of 'Unable to fetch alerts', return 'No alerts found for state CA. Verify the state code is valid (e.g., CA, NY). If the issue persists, try get_forecast() for the location.'
• Add tool annotations to schema. Mark all three tools with readOnlyHint: true to signal they are safe to call without user confirmation.
