WHAT IT DOES

What gt_formula_create does on Ruflo

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

RISK

Why gt_formula_create is rated Medium

This tool creates new formula definitions, which is a reversible write operation. It does not execute code, delete data, or move money. The severity is medium because malicious formula definitions could potentially be chained with other tools (like agent_spawn or execution contexts) to cause harm, but the tool itself only stores configuration.

From the tool's definition Tool name 'gt_formula_create' and description 'Create a custom formula definition' indicate creation of new data/configuration artifacts. The verb 'Create' and noun 'formula definition' establish this as a write operation that adds reversible state.
