Strong tool naming (verb_noun pattern), comprehensive parameter schemas with type constraints and descriptions, and detailed descriptions for most tools. All 9 tools have explicit registrations with schemas visible in src/server.ts. Good use of Zod for validation (snowflake regex, min/max bounds, enums). However, output schemas are not documented, LLMs cannot predict response structure. Error handling returns actionable messages but lacks categorization (retryable vs fatal). Some parameter descriptions could be more concise (discord_find_messages is verbose). No tool annotations (readOnlyHint/destructiveHint) despite clear risk levels.

• Document output schemas for all tools. Example: discord_list_guilds returns {guilds: [{id: string, name: string, member_count: number}], total: number}. Include field types and descriptions so LLMs can plan chaining.
• Add tool annotations to schema. For WRITE tools (discord_sync_member_snapshot, discord_sync_community_history, discord_analyze_growth), add destructiveHint: true or idempotentHint: true to help agents reason about safety and retry logic.
• Enhance error handling with structured error codes. Return {error: 'GUILD_NOT_FOUND', message: '...', retryable: false} instead of plain text. This enables agents to classify and respond appropriately.
• Simplify discord_find_messages description. Reduce from ~250 chars to ~100 by moving intent requirements ('Requires Message Content Intent') to a separate 'prerequisites' field or parameter description.
• Add pagination to list tools. discord_list_guilds and discord_list_channels should accept limit and offset parameters, return total count, and document max result size (e.g., 'Returns up to 100 guilds; use offset for pagination').
