Server has 11 tools with basic schemas and descriptions in German. All tools are READ_ONLY and follow verb_noun naming (get_*, search_*). However, descriptions lack LLM-optimization guidance, parameter descriptions are minimal, and output schemas are not documented. No error handling guidance, no pagination support despite potentially large result sets, and no tool annotations. Schemas are present but sparse, most parameters lack detailed constraints or format specifications.

• Document output schemas for all tools. Include field names, types, and examples. E.g., get_near_earth_objects should return {asteroids: [{id, name, diameter_km, velocity_kmh, distance_km, hazard_score}], total_count}.
• Expand parameter descriptions with format, range, and constraints. E.g., 'start_date (YYYY-MM-DD, required, must be ≤ today, max 7 days before end_date)' instead of 'Startdatum im Format YYYY-MM-DD'.
• Add pagination to search_nasa_images, get_natural_events, and get_exoplanets. Accept page/limit params, return total_count and next_cursor. Cap default limit at 20, max at 100.
• Implement error handling with recovery guidance. Catch API errors (rate limits, timeouts, 404s) and return structured errors: {error: 'rate_limit_exceeded', retry_after_seconds: 60, message: 'NASA API rate limit hit. Retry after 60 seconds.'}.
• Translate descriptions to English (or primary agent language). German descriptions reduce LLM reasoning clarity and limit international adoption.
