update_annotation

update_annotation edits an existing annotation: its message, its position, its size, or any combination. Omitted parameters keep their current value. Get the id from get_annotations first. Example prompt: “Reword comment 3 to mention the new deadline”.

Tool description (as the AI agent sees it):

Updates an existing annotation’s message and/or bounding box, then saves the result back to storage. Supports PDF, DOCX, XLSX, PPTX, and 50+ more document and image formats. Call get_annotations first to retrieve the annotation ‘id’ and current values. Pass any subset of message/x/y/width/height — omitted parameters keep their current value. Call this tool whenever the user asks to edit, modify, move, or resize an existing annotation. Do NOT pre-check whether files exist — pass the filename the user provided directly. Returns a saved-path message (‘Updated annotation in ’). On failure, the response text starts with ‘Annotation update failed for’ followed by the underlying exception type, message, and inner-exception chain.

Example call

{
  "name": "update_annotation",
  "arguments": {
    "file": {
      "filePath": "contract_annotated.pdf"
    },
    "id": 3,
    "message": "Deadline moved to 15 March \u2014 please confirm"
  }
}

Result

A message of the form Updated annotation <id> in <file> naming the saved document.

Pass only what changes: sending just message keeps the box where it was; sending x/y moves the annotation without touching its text.

On failure the text starts with Annotation update failed for, followed by the exception type and message.

Example prompts

  • “Reword comment 3 to mention the new deadline.”
  • “Move the annotation on page 2 down a little — it covers the table header.”
  • “Make annotation 5 bigger so it covers the whole clause.”
