Server has 12 tools with basic schemas and descriptions, but significant quality gaps. All tools have descriptions (positive), but most are brief (avg ~60 chars, well below 194-char baseline). Schemas are present but minimal, most lack parameter descriptions entirely. No error handling guidance, no output schemas documented, no tool annotations. Naming is inconsistent: 'lead_target' is vague (what does 'lead' mean?), while 'get_current_time' and 'calendar_list' follow verb_noun convention. Parameters like 'resp_id' lack context. No evidence of idempotency, pagination, or composition patterns. Security concern: no visible permission gating for destructive tools (calendar_delete, sheets_write). Overall, definitions are skeletal, functional but not LLM-optimized.

• Add parameter descriptions to all tools. For each parameter, specify: purpose, expected format/type, constraints (enum, range, pattern), and examples. E.g., 'resp_id: integer, conversation session ID (1 - 999999), required'.
• Document output schemas for all tools. Define response structure: field names, types, and whether results are paginated. E.g., 'Returns {files: [{name: string, url: string, size: integer}], total: integer}'.
• Rename 'lead_target' to 'confirm_goal_completion' or 'mark_goal_achieved' to clarify intent. Ensure tool names follow verb_noun convention and are unambiguous.
• Add error handling guidance to destructive tools (calendar_delete, sheets_write). Include: 'Returns error if event_id not found. Retryable: no. Suggest: verify event_id via calendar_list before deleting.'
• Expand tool descriptions to 100 - 200 characters. Include WHEN to use (e.g., 'Call after calendar_list to fetch full event details'), WHAT it returns, and any prerequisites (e.g., 'Requires Google Calendar OAuth scope').
