# Action Callbacks Pattern
# Use the `run` keyword for deterministic post-action processing
#
# ★ When To Use This Pattern:
#   - You need guaranteed follow-up after an action completes
#   - Audit logging or notifications must ALWAYS happen
#   - Chain multiple actions where order matters
#
# ★ Key Insight:
#   The `run` keyword executes AFTER the parent action completes.
#   This is deterministic (not LLM-decided) - the callback ALWAYS runs.
#   Use this when you can't afford to skip follow-up steps.
#
# ★ Validation Impact:
#   - [5 pts] Actions with proper callback structure
#   - Avoid nested run (only 1 level of nesting allowed)
#
# This is a PARTIAL template - integrate into a complete agent file

				customer_id: string
					description: "Customer identifier"
				items: list[string]
					description: "List of item SKUs"
				total: number
					description: "Order total amount"
			outputs:

	reasoning:
		instructions: ->
			| Help the customer place their order.
			| Ensure confirmation is sent after successful orders.
			| All order activities must be logged for compliance.
		actions:
			# This action uses callbacks to guarantee follow-up
			process_order: @actions.create_order
				with customer_id=@variables.customer_id
				with items=...
				with total=...
				set @variables.order_id = @outputs.order_id
				set @variables.order_status = @outputs.status
				# Callback 1: Always send confirmation after order created
				run @actions.send_confirmation

# ★ Anti-Pattern: Nested run (DO NOT DO THIS)
#
# process: @actions.first
#    run @actions.second
#       run @actions.third   # ❌ INVALID - nested run not allowed
#
# ★ Correct Pattern: Sequential callbacks (all at same level)
#
# process: @actions.first
#    run @actions.second     # ✅ First callback
#    run @actions.third      # ✅ Second callback (runs after second)

# ═══════════════════════════════════════════════════════════════════════════════
# ★ Pattern 2: Simple Variable Updates (No Callback Needed)
# ═══════════════════════════════════════════════════════════════════════════════
#
# For simple operations like incrementing counters or storing outputs,
# use `set` statements directly - NO `run` keyword needed.
#
# ⚠️ IMPORTANT: This pattern works in BOTH GenAiPlannerBundle AND AiAuthoringBundle
#    The `run` keyword ONLY works in GenAiPlannerBundle (not AiAuthoringBundle)
#    Use `set` statements for AiAuthoringBundle deployments
#
# Example: Create case and track count (works in BOTH bundle types)

subagent case_management:

				inp_Subject: string
					description: "Subject line for the case"
			outputs:
				out_CaseNumber: string
					description: "Generated case number"
				out_CaseId: string
					description: "Salesforce ID of the created case"
			target: "flow://Create_Case"

	reasoning:
		instructions: ->
			| Help the customer create support cases.
			| Track case count for session statistics.
		actions:
			# ✅ Simple pattern - just use `set` for variable updates
			create_support_case: @actions.create_case
				with inp_CustomerId=@variables.ContactId
				with inp_Subject=...
				set @variables.case_number = @outputs.out_CaseNumber
				set @variables.case_id = @outputs.out_CaseId
				set @variables.cases_created = @variables.cases_created + 1  # Direct increment!

# ⛔ INVALID KEYWORDS - NEVER USE THESE
# ═══════════════════════════════════════════════════════════════════════════════
#
# The following keywords DO NOT EXIST in Agent Script. Using them causes:
#   SyntaxError: Unexpected '[keyword]'
#
# ❌ internal_actions  - Does not exist (Claude may invent this for "local helpers")
# ❌ helper_actions    - Does not exist
# ❌ private_actions   - Does not exist
# ❌ local_actions     - Does not exist
#
# If you need simple variable operations after an action, use `set` directly:
#
# ❌ WRONG (internal_actions does not exist):
#
# internal_actions:
#    increment_counter:
#       set @variables.count = @variables.count + 1
#
# reasoning:
#    actions:
#       process: @actions.create_case
#          run @actions.increment_counter   # ❌ Can't reference internal action
#
# ✅ CORRECT (use set directly in the action block):
#
# reasoning:
#    actions:
#       process: @actions.create_case
#          set @variables.count = @variables.count + 1  # ✅ Direct set works!
