# Deterministic Routing Template (Zero-Hallucination Pattern)
# ============================================================
#
# This template demonstrates the zero-hallucination intent classification
# pattern using action output flags to control LLM behavior.
#
# Pattern: Classify intent deterministically, route without hallucination
# Use when: Critical routing decisions that must not be influenced by LLM creativity
#
# KEY PATTERN:
# In Agentforce Assets, set action outputs with:
# - is_displayable: False  (LLM cannot show this to user)
# - is_used_by_planner: True  (LLM can use for routing)
#
# This ensures the LLM routes based on classification but cannot
# generate hallucinated responses based on the classification data.
