Server defines 8 tools with consistent naming (verb_noun pattern) and basic descriptions. All tools have input schemas with type definitions and parameter descriptions. However, descriptions are terse (10-60 chars, well below the 194-char baseline), output schemas are defined in code but not exposed to the LLM, and error handling is minimal. No tool annotations (readOnlyHint/destructiveHint) despite 7 read-only and 1 write tool. Parameter descriptions lack format constraints and validation guidance. Missing pagination documentation for list-returning tools.

• Expand tool descriptions to 100-200 characters. Example: 'leaderboard_get' → 'Fetch top products from Product Hunt leaderboard for a given period (daily/weekly/monthly) and optional date. Returns up to 50 products ranked by votes. Use this to discover trending products or compare performance across time periods.'
• Add tool annotations via mcp.Tool fields: set ReadOnlyHint=true for all read tools, DestructiveHint=true for cache_clear, IdempotentHint=true for all read tools. This enables LLMs to reason about safety.
• Expose output schemas in tool registration. Modify mcp.AddTool to include OutputSchema field documenting the response structure (e.g., {period, date, total, items[{id, name, votes, ...}]}).
• Add min/max constraints to numeric parameters and enum values to string parameters. Example: limit parameter should declare min=1, max=50; period should declare enum=[daily, weekly, monthly].
• Document pagination in category_list and search_products descriptions: 'Returns paginated results (default 20 per page). Use offset/limit or page parameters to navigate. Total count included in response.'
