 ## Tool Usage
 
 - When consulting with the Codex MCP tool, use model `gpt-5.4`.
+- When a task requires setting up or controlling system state (sites, templates, instances, data connections, deployments, security, etc.) and the Central UI is not needed, prefer the ScadaLink CLI over manual DB edits or UI navigation. See [`src/ScadaLink.CLI/README.md`](src/ScadaLink.CLI/README.md) for the full command reference.
