Three tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names follow verb_noun convention (greet, transfer_image, analyze_image), which is good. However, descriptions are minimal (10-30 chars), parameter descriptions lack detail about constraints/formats, and output schemas are not documented. No error handling guidance, no idempotency markers, and no indication of which operations are destructive. The transfer_image tool performs a WRITE operation but lacks confirmation/dry-run patterns. Overall structure is present but falls short of production quality.

• Expand tool descriptions to 100-200 chars. Example: 'greet' → 'Greet a person by name. Returns a personalized greeting message. Use this to generate friendly introductions or acknowledgments.'
• Document output schemas for each tool. Specify return type (string, object, array), field names, and types. Example: greet returns {greeting: string, timestamp: string}.
• Add parameter constraints in descriptions. Example: 'Path to the source image file (absolute or relative path; supported formats: PNG, JPG, GIF; max 50MB).'
• Implement confirmation pattern for transfer_image. Add a 'dry_run' boolean parameter (default false) so agents can preview the operation before executing.
• Add tool annotations to the MCP tool definitions. Use destructiveHint=true for transfer_image and idempotentHint=true for greet and analyze_image.
