WHAT IT DOES

What theme_set_stylebox does on Godot Breakpoint

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

RISK

Why theme_set_stylebox is rated Medium

Although the description includes the word 'DESTRUCTIVE' in parentheses, the actual operation—setting a StyleBox entry and saving it to a Theme resource file—is reversible (the previous state can be restored by re-saving with different values or reverting the file). The 'DESTRUCTIVE' qualifier appears to be a developer note about file I/O impact rather than indicating irreversible data loss.

From the tool's definition The description explicitly states 'writes a file' and 'save it', indicating reversible modification of a Theme resource file via a res:// path. The tool loads and updates StyleBox entries on a Theme resource.

RECOMMENDED RULE

The rule that runs theme_set_stylebox safely

theme_set_stylebox Rate-limited

theme_set_stylebox stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
