WHAT IT DOES

What bulc_set_fds_fire_source does on BULC Building Designer

AI agents use bulc_set_fds_fire_source to create or update resources in BULC Building Designer — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your BULC Building Designer environment.

WHY IT NEEDS A POLICY

Why bulc_set_fds_fire_source needs a policy

This tool modifies/configures an existing furniture item by setting it as a fire source in the FDS simulation. It is a reversible configuration change (write operation) rather than executing a simulation or destructively removing data. The severity is medium because misconfiguring fire source parameters could corrupt simulation setups, but the action itself is a targeted write to a simulation object.
