Single tool 'get_todays_date' has minimal definition quality. Description is present but extremely brief (18 chars, below 20-char threshold). Input schema is empty object {} with no parameters documented. Tool is registered via @bright_data_agent.tool_plain decorator but lacks structured schema definition. No parameter descriptions, no output schema documentation, no error handling guidance. Naming is acceptable (verb_noun pattern) but overall definition falls well below production baseline.

• Expand description to 50-150 chars: 'Returns the current system date and time in ISO 8601 format (YYYY-MM-DD HH:MM:SS). Use this to provide context-aware responses when users ask about timing or scheduling. Safe to call multiple times.'
• Document output schema explicitly: specify return type is string, format is ISO 8601 datetime, and example value '2025-01-15 14:30:45'.
• Add tool annotation for idempotency: mark tool with idempotentHint=true so agents know it's safe to retry without side effects.
• Add error handling: document what happens if system clock is unavailable or timezone is misconfigured, and provide recovery guidance.
• Consider adding optional timezone parameter: allow caller to specify timezone (e.g., 'UTC', 'America/New_York') to make tool more flexible for multi-region agents.
