Server has 10 tools with basic descriptions and input schemas, but significant gaps limit production readiness. All tools have descriptions (10-100+ chars), and most parameters have type definitions. However, descriptions are often generic and lack actionable context for LLM selection. No output schemas documented. Error handling is minimal, most tools return plain strings without structured guidance. Parameter descriptions are sparse (e.g., 'Device IP address or alias/name' repeated across all tools). No enum constraints, validation ranges, or dependency hints. Tool composition is reasonable (single responsibility), but missing idempotency guarantees and recovery guidance.

• Add structured output schemas to all tools. Document return fields (e.g., discover_devices returns [{alias, model, ip, is_on, device_type, brightness?, color_temp?}]). Include field types and descriptions.
• Enhance parameter descriptions with validation rules and enums. E.g., 'brightness: integer 1-100 (required for dimmable lights)' and 'action: enum ["on", "off"]' for control_strip_outlet.
• Implement error classification and recovery guidance. Replace 'does not support brightness control' with 'Device does not support brightness. Call discover_devices() to check device capabilities, or try set_color_temp() for tunable lights.'
• Support environment variable secret injection (TAPO_USERNAME, TAPO_PASSWORD) as fallback to Keychain. Enable cross-platform deployment and CI/CD integration.
• Add dry-run or confirmation support for destructive operations. E.g., turn_off could accept a 'confirm' parameter or return a confirmation token that must be passed in a follow-up call.
