Server has 9 tools with schemas and descriptions present, but quality is inconsistent. Naming follows verb_noun convention (reminder_create, bot_power_off, datetime_now). However, descriptions are minimal (10-50 chars for most tools), parameter descriptions are sparse or missing, and output schemas are entirely undocumented. Three datetime tools (datetime_now, now, get_date) are near-duplicates with overlapping functionality, violating single-responsibility principle. Error handling is present in code but not documented in tool definitions. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk levels. Parameters like 'tz', 'at_ms', 'locale_format' lack format/constraint documentation. Critical: reminder_create and bot_power_off are destructive operations with no confirmation or dry-run pattern.

• Consolidate datetime_now, now, and get_date into a single 'get_datetime' tool with optional parameters (include_weekday, include_day_of_year, locale_format) to eliminate ambiguity and reduce LLM decision overhead.
• Add tool annotations: mark reminder_create, bot_power_off, reminder_cancel as destructiveHint=true; mark reminder_list, bot_power_status, datetime_now, now, get_date as readOnlyHint=true. This signals operation safety to agents.
• Document output schemas for all tools. E.g., reminder_create returns {id: string, dueAtMs: int, text: string, createdAtMs: int}; reminder_list returns {reminders: [{id, dueAtMs, text}], total: int}.
• Expand parameter descriptions to 50-100 chars with format/constraint guidance. E.g., 'tz: IANA timezone name (e.g., Asia/Shanghai, UTC, America/New_York). Defaults to Asia/Shanghai if not provided.'
• Add confirmation pattern for destructive tools: reminder_create and bot_power_off should support a 'dry_run' parameter that returns what would happen without executing, or require explicit 'confirm=true' parameter.
