First readmethods and parameters, then follow thebatch recipeand execute using the real returned IDs.
Create a standalone vector illustration sample; for real tasks, first clarify the retention scope, which objects participate in the mask, and the topmost mask path. For existing artwork, select only authorized objects; do not use select.all.
Use a circular mask to reveal two color planes without cropping the original rectangles; after saving and reopening, the Clip Group and complete child objects still remain, and saving a copy and releasing the mask restores the outer content.
Methods, parameters, and batches are all within this skill. Do not treat the manual's $ref or capture directly as native command parameters; do not run file.new on existing artwork. Keep the same MCP editor within the host; for CLI file tasks, explicitly save and reopen.
Deliver a native editable project and the agreed exports, check SVG and PNG, and do not judge only by command success. Synthetic examples do not represent real design quality or that synchronization to the target host has been accepted.
