NotchMate exhibits significant definition quality gaps. While 10 tools are registered with names and descriptions, most descriptions are in Russian and lack the 50-200 char LLM-optimized range (baseline: avg 194 chars). Input schemas are present but sparse: most tools have minimal parameters with no type constraints or validation guidance. Parameter descriptions are often missing or trivial. No output schemas are documented. Error handling is absent, tools provide no recovery guidance. The server targets a single user (personal productivity) rather than multi-user agent patterns, limiting composability. Tool names follow verb_noun convention (get_today, add_note, search_notes, start_focus, stop_focus, jira_log_time, calendar_events, media_control, call_recording, show_message) but descriptions lack actionable context for LLM selection.

• Translate all tool descriptions and parameter descriptions to English. Use 50-200 character descriptions optimized for LLM selection (e.g., 'get_today: Retrieve user's daily summary including focus timer status, active Jira task progress, calendar events, and music playback state. Call when user asks about their day or current tasks.').
• Document output schemas for all tools. For get_today, specify: {task_id, task_key, elapsed_minutes, remaining_minutes, calendar_events: [{title, start_time, end_time}], ...}. For search_notes, specify: {results: [{title, snippet, file_path}], total_count}.
• Add min/max constraints to numeric parameters: start_focus minutes (1-480), calendar_events days (1-7), show_message text (1-60 chars). Add length/format constraints to strings: add_note text (1-5000 chars), search_notes query (1-200 chars).
• Add error handling guidance to write tools. E.g., jira_log_time: 'If task key is invalid, returns error with available task keys. If time exceeds task estimate, returns warning but proceeds. Retryable on network timeout.'
• Implement tool annotations (readOnlyHint, destructiveHint, idempotentHint) in MCP schema. Mark get_today, search_notes, calendar_events as readOnlyHint=true. Mark jira_log_time, add_note, call_recording as destructiveHint=true.
