Server has 13 tools with basic naming (verb_noun pattern) and descriptions present. However, critical gaps undermine quality: most parameter descriptions are minimal (1-5 words), input schemas lack type definitions beyond string, output schemas are undocumented, and error handling is absent. Tool names are clear but descriptions average ~40 chars (below 194-char baseline). No evidence of pagination, result limits, or structured output documentation. Composition is reasonable (single-responsibility tools), but parameter validation and LLM-friendly guidance are missing.

• Document output schemas for all tools. E.g., 'Returns: {id: string, email: string, name: string, avatar_url: string, ...}' so LLMs know what fields to extract.
• Expand parameter descriptions to 50-100 chars with format/constraint hints. E.g., 'avatarId: The unique identifier of the avatar (UUID format, e.g. 550e8400-e29b-41d4-a716-446655440000).'
• Add enums for constrained parameters. E.g., 'service' in search_profiles_by_verified_account should list valid services: ['twitter', 'github', 'linkedin', ...].
• Add error handling guidance to tool descriptions. E.g., 'If avatar not found, returns 404 with message. Retry with get_avatars() to list available avatars.'
• Implement confirmation pattern for delete_avatar: add a 'confirm' boolean parameter (default false) or a separate 'confirm_delete_avatar' tool to prevent accidental destruction.
