- Add database connection retry logic (3 attempts, 5s delay) - Add missing database functions: get_task_by_id, get_agent_execution, approve_agent_execution, update_agent_config, update_execution_status - Complete agent execution approval workflow - Fix agent executor to handle approved executions - Fix inefficient task queries (use direct ID lookup) - Add error action handling in agent executor - Improve LiteLLM error handling with specific exception types - Reduce LiteLLM timeout from 60s to 30s - Fix execution status update to only set started_at once - Consolidate WebSocket datetime serialization with helper function - Implement update agent endpoint
