Claude Code: deny. ### `add_keyline` - The name "add_keyline" says "add": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Apply a keyline to the explicit elementId and areaId. Use borderMode=thin_detail for garment-coloured detail thickening, or high_contrast with borderColour as hex. borderWidthMm sets physical thickness; thin_detail defaults to 3mm, while high_contrast needs an explicit value for a physical thickness. ``` ### `align_element` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Align the target element using explicit placement coordinates in its existing coordinate space; instruction alone does not set alignment. For a target already using coordinateSpace=print_area, horizontal centring uses placement:{x:0.5}, preserving y and all other geometry. Text alignment within its box is separate from the box position. Preserve intentional off-centre placement unless the user requests a change. ``` ### `apply_design_batch` - The name "apply_design_batch" says "apply": a word for a change. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Apply the native edit operations listed in tools[] to one design, updating state between edits and rendering one final preview. Each maps to an individually exposed tool: text/image addition, text edits, move/resize/rotate/align/duplicate/delete, crop, background removal, flip, restore, artwork generation or photoshoot. Use explicit elementId/areaId and native text/asset/placement/options objects; standalone workflow shorthand is not normalized inside a batch. May overwrite or delete content.

Description, as the server wrote it: ```untrusted-server-text Apply the existing natural-language edit to the current design: text/content/style, image replacement, sizing, positioning, background removal, crop/flip/restore, contrast, keyline or emoji changes. These capabilities also have individually named tools in this list. Preserve the user's exact instruction and intended element/print area. Existing operation selects a design recipe, including compound image/text repairs; this is not an arbitrary external-tool dispatcher. Edits can overwrite content. Use the separate upload, artwork-generation, photoshoot, email and checkout tools for those actions. ``` ### `choose_product` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true).

Description, as the server wrote it: ```untrusted-server-text Replace existing text content or edit its style. This can overwrite the selected wording. Resolve targets from session state. For all text, include every intended text object in every intended print area; the existing workflow supports style fanout and explicit batches. ``` ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `email_design` - The description's first verb is "send": a word for sending, and what is sent cannot be taken back. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Tag outbound: The description's first verb is "send": it sends or publishes something to other people. Description, as the server wrote it: ```untrusted-server-text Send a saved design link to the user's explicitly requested recipient using the existing sharing service.
