Three tools with minimal descriptions (10-30 chars), no parameter descriptions, and incomplete schemas. get_notes_list has empty input schema {}; get_note and add_note use Zod validation but lack formal schema documentation. No error handling guidance, no output schema documentation, and no tool annotations. Naming is acceptable (verb_noun pattern) but descriptions are far below the 194-char baseline for production tools. This server reads like a prototype, not production-grade.

• Expand get_notes_list description to ~100-150 chars: 'Retrieve all sticky notes. Returns a list of note IDs and truncated text (first 30 chars). Call this first to discover available notes before fetching individual content.'
• Expand get_note description: 'Retrieve the full content of a sticky note by ID. Returns the complete text, theme, timestamps, and metadata. Use after get_notes_list to fetch a specific note.'
• Expand add_note description: 'Create a new sticky note with the given text. Modifies state, returns success/failure message and the new note ID. Requires a valid user in the database.'
• Document output schemas for all three tools. E.g., get_notes_list returns {notes: [{id: string, text: string}]}; get_note returns {id, text, theme, createdAt, updatedAt}; add_note returns {success: boolean, noteId?: string, message: string}.
• Add error handling: if db_path is unset, return 'Database path not configured. Set db_path environment variable.'; if note not found, return 'Note ID not found. Call get_notes_list to see available notes.'
