WHY IT NEEDS A POLICY

Why generate_color_palette needs a policy

This tool creates or produces a new color palette artifact, which is a write operation. The generated palette is design data that can be modified or discarded, making it reversible. The blast radius of misuse is minimal—worst case, an AI generates an aesthetically poor or brand-non-compliant palette that a human designer would reject or override.

From the tool's definition Tool description: 'Generate a color palette based on harmonies and brand guidelines' — the verb 'generate' indicates creation of new data (a color palette). No destructive overwrite, no code execution, no financial transaction, and no irreversible deletion.
