The Pokemon Server has basic tool definitions with proper naming and schemas, but falls short on description quality and lacks depth in parameter documentation. Both tools follow verb_noun naming conventions (get_pokemon, compare_pokemon), which is good. Input schemas are properly defined with type information and required flags. However, tool descriptions are extremely brief (under 50 chars), parameter descriptions lack actionable detail about format/constraints, and there is no documented output schema. The tools are READ_ONLY and relatively simple, which limits complexity issues, but the lack of comprehensive parameter guidance and missing output documentation significantly impact LLM reasoning and error recovery.

• Expand tool descriptions to 80-150 chars. Example for get_pokemon: 'Fetch detailed stats for a Pokemon including height, weight, types, and base stats. Call this to answer questions about a single Pokemon. Requires lowercase name (e.g., pikachu, charizard). Returns HTTP 404 if not found.'
• Add recovery guidance to error messages. Example: 'Pokemon "Pikachu" not found. Did you mean: pikachu, pikachuu? Try lowercase names or use search_pokemon for partial matches.'
• Document output schemas explicitly. Add a comment or schema definition showing that get_pokemon returns {name, height, weight, types: [string], stats: [{name, base_stat}]}
• Normalize input: convert parameter names to lowercase inside tool handlers rather than requiring LLM to do it. Replace the manual validation 'name, ok := arguments["name"].(string)' with automatic normalization: name = strings.ToLower(name)
• Add enum constraints or pattern validation. If only lowercase is valid, document as: 'Pokemon name (lowercase only, 1-20 chars, alphanumeric+dash). Example: pikachu, mr-mime'
• Consider adding a search_pokemon tool to handle partial or case-insensitive lookups, reducing errors when LLMs do not recall exact names.
• Document API rate limits and timeouts in tool descriptions to guide agent retry logic.
