All Keys

Name	Type	Default	Env Var	Description
enabled	bool	True	LEX_AI_AGENTS__ENABLED	Enable the AI agents subsystem
max_iterations	int	10	LEX_AI_AGENTS__MAX_ITERATIONS	Maximum reasoning iterations per execution
default_temperature	float	0.7	LEX_AI_AGENTS__DEFAULT_TEMPERATURE	Default temperature for LLM calls
default_max_tokens	int	2048	LEX_AI_AGENTS__DEFAULT_MAX_TOKENS	Default max tokens for LLM responses
tool_max_retries	int	3	LEX_AI_AGENTS__TOOL_MAX_RETRIES	Number of retries for transient tool execution errors
enable_tracing	bool	True	LEX_AI_AGENTS__ENABLE_TRACING	Enable OpenTelemetry tracing
enable_metrics	bool	True	LEX_AI_AGENTS__ENABLE_METRICS	Enable Prometheus metrics

Env Var Override

Environment variables use prefix LEX_AI_AGENTS__:

export LEX_AI_AGENTS__MAX_ITERATIONS=25
export LEX_AI_AGENTS__DEFAULT_TEMPERATURE=0.5
export LEX_AI_AGENTS__TOOL_MAX_RETRIES=5

Disabling

Set enabled: false to skip agent service registration entirely. The provider exits early during register().

Limits

• max_iterations: min 1
• default_temperature: 0.0–2.0
