Critical gaps across all dimensions. Tool definitions are inferred from metadata object in mcpb/server/index.mjs rather than explicit schema registration. No input schemas visible in source code, cannot verify parameter types, constraints, or descriptions. Tool descriptions are present but extremely brief (10-20 chars), below the 50-200 char LLM-optimized baseline. No parameter documentation. No output schema documentation. No error handling guidance. The server acts as a wrapper around an external Mint CLI binary, delegating actual tool implementation, tool definitions are not directly visible in the MCP server code itself.

• Add explicit JSON Schema input definitions for all tools. Include parameter types (string, number, boolean, array), constraints (enum, minLength, pattern), and descriptions (50-100 chars each). Example: mint_status should document any required parameters like 'include_details' (boolean, default false).
• Expand tool descriptions to 80-150 characters. Include WHAT the tool does, WHEN to use it vs similar tools, and WHAT it returns. Example: 'Inspect current Mint storage status including total size, reclaimable space, and last scan timestamp. Call this first to understand storage state before running mint_scan.'
• Document output schemas for each tool. Specify returned fields, types, and structure. Example: mint_status returns {total_size_bytes: number, reclaimable_bytes: number, last_scan_iso8601: string, scan_in_progress: boolean}.
• Add a dry-run parameter to mint_execute: 'dry_run' (boolean, default true). Require explicit dry_run=false to move items to Trash. Return what would be deleted before actual execution.
• Add error handling guidance in tool descriptions. Example for mint_execute: 'Returns {success: boolean, moved_count: number, failed_items: array, error_message?: string}. If some items fail, returns partial success with details on which items could not be moved.'
