This server has 2 tools with basic functionality but significant quality gaps. Both tools have descriptions that are present but lack precision and fail to meet LLM-optimization baselines. Naming is reasonable (verb_noun pattern) but descriptions are generic. Input schemas are minimally structured, add_note has a basic string parameter but read_notes has an empty input object. Output schemas are completely undocumented, violating the critical baseline that '100% of A+ tools have documented return types.' Error handling is absent: tools do not guide recovery or categorize failures (pattern:recovery-guide). No parameter validation or actionable error messages. The server includes a resource (notes://latest) and prompt (note_summary_prompt) which add some feature completeness, but core tool quality is weak. Average tool score: 38/100.

• Expand add_note description to ~100-150 chars: 'Add a new note to the sticky notes file. Each note is stored as a separate line. Use when the user wants to record a new item, task, or reminder. Returns a confirmation message. Note: this operation is permanent once added.'
• Expand read_notes description to ~100-150 chars: 'Retrieve all notes from the sticky notes file as a newline-separated list. Use this before summarizing, filtering, or checking for existing notes. Returns all notes or "No notes yet" if empty.'
• Document output schemas explicitly. For add_note, state: 'Returns: {"status": string, "message": string}' or similar. For read_notes, state: 'Returns: {"notes": string, "count": integer}'.
• Add input validation: check for null/empty message in add_note, return error like 'message cannot be empty' instead of silently adding blank lines.
• Add try-catch blocks and return actionable errors: 'Failed to add note: file is read-only' or 'Failed to read notes: file not found (expected at <path>).'
• Add tool annotations: mark add_note with destructiveHint=true to signal state modification to the LLM.
• Consider adding limit and offset parameters to read_notes, or document a hard limit (e.g., 'returns up to 1000 most recent notes') to prevent context explosion.
