The techniques are: (1) semantic tool selection — dynamically filtering which tools enter the context window using vector search to cut token usage from ~3,000 to under 300; (2) GraphRAG — replacing vector retrieval with Neo4j Cypher queries for aggregation and counting tasks that require precise, verifiable answers; (3) multi-agent validation — using a Strands Swarm of executor, validator, and critic agents to catch fabricated success responses; (4) neuro-symbolic guardians — enforcing business rules (max guests, payment before confirmation, date validation) in Python hooks that fire before tool execution, making them impossible for the model to bypass; and (5) runtime steering — using an agent-control server to register soft rules that redirect the agent (e.g., split a 50-guest booking into multiple rooms) rather than hard-blocking. Production deployment via Amazon Bedrock Agent Core is also covered, providing managed runtime, gateway, memory, and observability without self-managed infrastructure. ## Full article daily.dev links to this article rather than hosting it.
