# LLM-Controlled Actions Pattern
# Demonstrates both deterministic and LLM-controlled action invocation
#
# ★ When To Use This Pattern:
#   - When the LLM should decide which actions to invoke based on context
#   - When actions should only be available under certain conditions
#   - When you want the agent to make intelligent choices about tool usage
#
# ★ Key Insight:
#   - Deterministic: "run @actions.x" - ALWAYS runs when code path is reached
#   - LLM-Controlled: "{!@actions.x}" in instructions - LLM decides based on context
#   - Tools in reasoning.actions - LLM chooses which to invoke
#
# ★ Two Invocation Methods:
#   1. Deterministic (run @actions.x): Use in before/after_reasoning, action callbacks
#   2. LLM-Controlled ({!@actions.x}): Reference in reasoning instructions
#
# This is a PARTIAL template - integrate into a complete agent file

# Variables for tracking action context
variables:
	# ... standard linked variables ...

	actions:

			description: "Retrieves order status by order ID"
			inputs:

					description: "The order ID to look up"
			outputs:
				status: string

				delivery_date: string

			target: "flow://Log_Interaction"

	# ★ Deterministic logging before reasoning
	before_reasoning:
		run @actions.log_interaction
			with interaction_type="order_inquiry"

	reasoning:
		# ★ LLM-Controlled: Reference actions in natural language
		# The LLM decides when to use these based on conversation context
		instructions: ->
			| Help the customer with their order inquiry.
			|
			| Available capabilities:
			| - Use {!@actions.get_order_status} to look up order details when they provide an order ID
			| - Use {!@actions.update_order} if they want to modify their order (requires confirmation)
			| - Use {!@actions.cancel_order} if they want to cancel (requires confirmation)
			|
			| Always confirm destructive actions before proceeding.
			| If they haven't provided an order ID, ask for it first.

		# ★ Tools: LLM chooses which to invoke based on conversation
		actions:
			# Slot filling - LLM extracts order_id from conversation
			lookup: @actions.get_order_status
				with order_id=...
				set @variables.order_id = @outputs.status

			# Conditional availability - only show when order ID is known
			update: @actions.update_order
				with order_id=@variables.order_id
				with changes=...
				available when @variables.has_order_id == True

			# Conditional availability with multiple conditions
			cancel: @actions.cancel_order
				with order_id=@variables.order_id
				with reason=...
				available when @variables.has_order_id == True
				available when @variables.order_status != "shipped"

			# Topic transitions
			go_help: @utils.transition to @topic.general_help
			go_escalation: @utils.transition to @topic.escalation
				available when @variables.needs_human == True

# ★ Insight: When to Use Each Method
#
# DETERMINISTIC (run @actions.x):
#   - Audit logging (must always run)
#   - Required follow-up actions
#   - Guaranteed side effects
#   - In before_reasoning / after_reasoning blocks
#   - In action callbacks (run after parent)
#
# LLM-CONTROLLED (reasoning.actions or {!@actions.x}):
#   - User-driven choices
#   - Context-dependent operations
#   - Optional actions based on conversation
#   - When intelligence is needed to decide
#
# CONDITIONAL (available when):
#   - Guard destructive operations
#   - Show options only when prerequisites met
#   - Enforce business rules

# ★ Example: Action Callback Pattern (Deterministic Chaining)
# Use "run" for guaranteed follow-up actions after a primary action
