When a Forge Rovo action is invoked, the platform auto-generates a confirmation ("preview") card that displays the action title and input values before the user confirms execution. Currently, there is no partner-facing API to customize, template, or control the contents of this card. The card is generated entirely by the runtime from the parsed tool inputs, with no render guarantee.

This creates a poor user experience in cases where:

• Input values are long JSON strings that are not human-readable in a card preview.
• The card renders blank (no input values shown) due to parsing issues on the platform side.
• The card shows raw field names and values that are not meaningful to end users.
