Server has 15 tools with basic naming and descriptions, but significant gaps in schema completeness and parameter documentation. Most tools lack detailed input schemas visible in source; descriptions are present but often generic (10-50 chars). No output schemas documented. Error handling is minimal. Tool composition is reasonable (each does one thing), but parameter descriptions are sparse and many lack type constraints. This is a typical community server with foundational structure but incomplete production-grade polish.

• Document output schemas for all tools. E.g., send_push_to_tag should return {success: bool, push_id: string, timestamp: ISO8601, error?: string}. This enables LLMs to chain calls and extract IDs.
• Expand parameter descriptions to 50-150 chars with format hints. E.g., 'criteria' in create_segment: 'JSON object defining segment rules (e.g., {"tag": "vip", "opt_in": true}). See docs for full schema.'
• Add error handling guidance to tool descriptions. E.g., send_push_to_tag: 'Returns error if tag does not exist (retryable with list_segments to find valid tags) or if API quota exceeded (wait 60s and retry).'
• Implement pagination for list_segments and list_skills. Add limit (default 20, max 100) and offset parameters. Return total_count and next_offset in response.
• Add tool annotations (readOnlyHint, destructiveHint) to clarify side effects. E.g., send_push_to_tag, send_message_center_message, create_segment, migrate_sdk should be marked destructiveHint=true.
