Server has 5 tools with basic schemas and descriptions, but significant quality gaps. All tools have input schemas with type definitions and descriptions present, meeting minimum requirements. However, descriptions are generic and lack LLM-optimized guidance on WHEN to use each tool or WHAT happens next. Parameter descriptions are minimal (e.g., 'Discord invite code' lacks format guidance). No output schemas documented, LLMs cannot predict response structure for chaining. Error handling is present but generic ('Error: {message}'). No tool annotations (readOnlyHint, destructiveHint, idempotentHint). Tool names are reasonably clear (verb_noun pattern) but lack specificity, 'analyze_server_engagement' doesn't clarify what 'engagement' means or what metric is returned. No pagination support documented despite tools returning lists. Baseline: avg tool description 194 chars; these average ~120 chars and lack context. Avg params per tool: 4 (matches baseline), but descriptions average ~40 chars vs. 72 char baseline.

• Document output schemas for all tools. E.g., search_public_servers should return {servers: [{name, member_count, description, invite_url}], total_count}. This enables LLM chaining and response parsing.
• Expand tool descriptions to 150-250 chars. Add WHEN to use (e.g., 'Use this AFTER search_public_servers to gauge activity before joining'), WHAT it returns (e.g., 'Returns online/total member ratio and activity level'), and NEXT STEPS (e.g., 'Use draft_community_message next').
• Add format constraints to parameters. E.g., server_invite: 'Discord invite code or full URL (discord.gg/XXX, discord.com/invite/XXX, or bare code like abc123def)'. Replace free-form strings with enums where possible (e.g., tolerance_level already has enum, good pattern).
• Add tool annotations to inputSchema. Mark all tools with readOnlyHint: true since they are read-only. This signals to agents that retries are safe and no side effects occur.
• Enhance error messages with recovery guidance. E.g., 'Invalid invite code. Try: (1) Check format (discord.gg/XXX), (2) Verify invite is not expired, (3) Use search_public_servers() to find active servers.' This guides agent retry logic.
