WHAT IT DOES

What ruvllm_hnsw_create does on Claude Flow

AI agents use ruvllm_hnsw_create to create or update resources in Claude Flow, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Flow environment.

RISK

Why ruvllm_hnsw_create is rated Medium

The tool creates a new HNSW (Hierarchical Navigable Small World) router instance compiled to WASM. This is a Write operation as it instantiates a new persistent routing structure. It does not execute arbitrary code or commands, nor does it delete or move money.

From the tool's definition 'Create a WASM HNSW router for semantic pattern routing' — this creates a new routing component/resource in the system
