Three tools with clear verb-noun naming (get_lamp_state, set_lamp_state, set_all_lamps) and detailed descriptions (150-200 chars). All tools have input schemas with typed parameters and descriptions. However, output schemas are not documented, LLMs cannot predict return structure. Parameter descriptions include ranges and constraints (e.g., 'Brightness level from 0 to 254'), which is good. Missing: error handling guidance, idempotency hints for write operations, and confirmation patterns for destructive actions. No tool annotations (readOnlyHint/destructiveHint) despite clear risk levels.

• Document output schemas for all three tools. Example: get_lamp_state returns {lamp_id: string, on: boolean, brightness: 0-254, hue?: 0-65535, saturation?: 0-254, color_temperature?: 153-500, automation_status: string, manual_override: boolean, hue_sync_enabled: boolean}.
• Add tool annotations: set_lamp_state and set_all_lamps should include destructiveHint=true and idempotentHint=false (1-hour override means repeated calls may have different effects).
• Add error handling guidance to descriptions: 'If lamp_id is invalid, call get_lamp_state first to discover available lamps.' Include actionable error messages in responses (e.g., 'Invalid lamp_id: xyz. Available: lamp_1, lamp_2, lamp_3').
• Implement a dry-run or confirmation pattern for set_lamp_state and set_all_lamps. E.g., add an optional 'confirm' parameter or return a confirmation token that must be passed in a follow-up call.
• Document lamp_id format and discovery in set_lamp_state description: 'The lamp ID (e.g., "1", "2"). Call get_lamp_state with no parameters to list all available lamps.'
