Single tool 'get+presentation' with significant quality gaps. Tool name violates verb_noun convention (uses '+' instead of '_'). Description is minimal (37 chars, below 50-char baseline for A+ tools). Input schema present but severely under-specified: single generic 'operation' parameter with no enum constraints, no description of what operations are valid, and no example values. Output schema completely undocumented, no indication of what fields the response contains, whether it's paginated, or how to chain results to other tools. No error handling guidance. Cannot verify tool registration from provided source (Application.java excerpt not shown), so tool definition appears inferred rather than explicitly visible in code.

• Rename tool from 'get+presentation' to 'list_presentations' (follows verb_noun convention). If filtering is needed, add separate 'search_presentations' tool.
• Add enum constraint to 'operation' parameter with explicit valid values: e.g., {"type": "string", "enum": ["list_all", "filter_by_year", "filter_by_title"]}. Include description for each operation.
• Expand tool description to 100-150 chars: 'List all available Java presentations with optional filtering. Returns presentation title, YouTube URL, and year. Use to discover available content before requesting details.'
• Document output schema: e.g., '{"type": "array", "items": {"type": "object", "properties": {"title": {"type": "string"}, "url": {"type": "string", "format": "uri"}, "year": {"type": "integer"}}, "required": ["title", "url", "year"]}}'. Include total_count if pagination is supported.
• Add error handling: 'If operation is invalid, returns error with valid options. If service unavailable, returns retryable error with hint to try again.'
• Provide full Application.java source showing tool registration, MCP server initialization, and tool handler implementation to verify proper SDK usage.
