The assigned complexity tier.
QueryTier
Retrieval strategy recommendation from the LLM-as-judge classifier.
When the classifier operates in strategy-aware mode, this field is populated directly from the LLM's structured output. When the classifier runs in legacy tier-only mode, the strategy is inferred from the tier via TIER_TO_STRATEGY.
RetrievalStrategy
Confidence score for the classification (0 to 1). A score below the configured threshold may trigger fallback behaviour.
Human-readable reasoning explaining why this tier was chosen. Useful for debugging and audit trails.
Whether the agent's internal knowledge is likely sufficient to answer
without any retrieval. When true and tier is 0, the router may skip
retrieval entirely.
Suggested source types to consult for this query.
['vector', 'graph']
Tool names the classifier believes are needed to answer this query. Empty array if no tools are required.
