Server provides 7 tools with complete JSON schemas and descriptions. Naming follows verb_noun convention (add, multiply, write_note, list_notes, greet). Descriptions are present but vary in quality, some are clear (write_note: 3 sentences explaining purpose and return value), others are minimal (add: 4 words). All tools have typed input schemas with required fields and parameter descriptions. However, output schemas are not documented, LLMs cannot predict return structure. Error handling is absent from tool definitions. No tool annotations (readOnlyHint, destructiveHint) despite clear risk classifications in metadata. Parameter descriptions are adequate but lack format/constraint details (e.g., 'number' type has no min/max bounds). write_note is marked WRITE but has no confirmation or dry-run pattern.

• Document output schemas for all 7 tools. Example: write_note should return {type: 'object', properties: {download_link: {type: 'string', description: 'URL to download the note file'}, file_path: {type: 'string'}, created_at: {type: 'string', format: 'date-time'}}}.
• Expand descriptions for add and multiply to 50 - 100 chars. Example: 'Add two numbers and return the sum. Use for arithmetic calculations. Supports integers and decimals; result precision depends on input magnitude.'
• Add tool annotations to all tools. Use readOnlyHint: true for add, multiply, list_notes, greet, current_setting, where_do_files_go. Use destructiveHint: true for write_note.
• Add numeric constraints to add/multiply parameters. Example: {a: {type: 'number', description: 'First number (range: -1e6 to 1e6)'}, b: {type: 'number', description: 'Second number (range: -1e6 to 1e6)'}}.
• Rename where_do_files_go to get_file_paths or check_file_configuration. Update description to: 'Check which file storage path is currently active (local, temp, or custom). Call this to verify the server setup before writing notes.'
