Single tool with adequate naming (verb_noun pattern) and basic schema. Description is present but generic (67 chars, below 194-char baseline). Parameter has type and description. No output schema documented. No error handling guidance. Tool returns unstructured string instead of structured object. Missing pagination, result limits, and recovery hints. Follows ~20% of 54 patterns.

• Document output schema: return structured JSON with fields {name: string, types: string[], abilities: string[], stats: {stat_name: string, base_stat: number}[]}. This enables LLM to extract and chain data.
• Expand description to 150 - 250 chars: 'Fetch Pokémon stats, types, and abilities by name. Returns structured data suitable for comparison or team building. Accepts lowercase names (e.g., pikachu, charizard). If name not found, suggests similar names.'
• Add error recovery guidance: 'If Pokémon not found, try search_pokemon_by_type() or list_pokemon_by_generation() to discover valid names.'
• Replace example value in parameter description with a constraint: 'The Pokémon name (lowercase, 1 - 50 chars). Accepts common names like pikachu, charizard, dragonite.'
• Cap results at 20 base stats and 10 abilities; document in description: 'Returns up to 10 abilities and 20 base stats. For full move list, call get_pokemon_moves().' This prevents context bloat.
