Tars has 8 tools with mostly complete schemas and descriptions. Naming is action-oriented (manage_*, web_*, discover_*, invoke_*). Descriptions range 50 - 250 chars, meeting baseline. However, several tools lack parameter descriptions or have vague language. manage_facts and manage_notes omit descriptions for key parameters ('key', 'value', 'queryOrContent'). manage_tasks has a complex schema with 10 parameters but some lack clarity on mutual exclusivity. Error handling is minimal, no recovery guidance or actionable error messages visible. Output schemas are not documented. Tools are well-composed (single responsibility), but parameter validation rules are not explicit in descriptions.

• Add explicit parameter descriptions to manage_facts ('key': 'Unique snake_case identifier for the fact, e.g. favorite_color, timezone'; 'value': 'The value to store, any string') and manage_notes ('queryOrContent': 'For add: note text; for search: keyword query').
• Document manage_tasks parameter interdependencies: 'For create: title, prompt, schedule, mode required. For delete/toggle/modify: id required. For list: enabledOnly optional, filters to enabled tasks only.'
• Add output schema documentation for each tool. E.g., web_search returns {results: [{title, url, snippet}], total_count}; manage_facts returns {facts: {[key]: value}} for list action.
• Implement error handling with recovery guidance. E.g., 'URL fetch failed: timeout. Try a shorter URL or check network connectivity.' instead of raw HTTP errors.
• Add validation rules to descriptions. E.g., manage_tasks schedule: 'Cron expression (e.g. 0 9 * * MON) or ISO 8601 datetime (e.g. 2025-01-15T09:00:00Z)'.
