Single tool 'add-note' has a basic schema and minimal description. The tool name lacks a clear action verb (should be 'create_note' or 'save_note'). Description is only 14 characters ('Add a new note'), below the 20-char minimum for scoring above 0-20 range. Input schema is present with proper types (string for name and content, both required), but lacks parameter descriptions, LLMs cannot infer what 'name' and 'content' mean without explicit guidance. No output schema documented. No error handling guidance. Tool performs a write operation but description does not state this. Prompts and resources are implemented but not evaluated here.

• Rename 'add-note' to 'create_note' to signal the action verb clearly and match LLM expectations for tool naming conventions.
• Expand tool description to 50-150 characters: 'Create a new note with a name and content. Returns the note name and confirmation. Use this to store information for later retrieval.'
• Add descriptions to input parameters: name='The unique identifier for the note (alphanumeric, 1-100 chars)', content='The note body text (plain text or markdown, max 10000 chars)'.
• Document the output schema: 'Returns an object with fields: note_name (string), content (string), created_at (ISO 8601 timestamp), status (string: success|error)'.
• Add validation and error guidance: catch duplicate names and return 'Note already exists. Use update_note() to modify it, or choose a different name.' Validate content length and return 'Content exceeds 10000 chars. Please shorten and retry.'
