What list_pipelines does on Ha Nexus Agent

AI agents call list_pipelines to retrieve information from Ha Nexus Agent without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list_pipelines is rated Low

This tool retrieves and queries existing pipeline configurations from Home Assistant's Assist system. It returns information about pipelines and metadata (preferred pipeline ID) without creating, modifying, deleting, or executing any operations. No side effects or state changes occur. The blast radius of misuse is minimal—an agent could only learn about existing pipelines, which is informational only.

From the tool's definition Tool name 'list_pipelines' and description 'List all Assist pipelines plus the preferred pipeline id' indicate data retrieval with no modification. The verb 'List' and 'plus' (informational addition) are characteristic of read-only operations.
