CloudCIX/guiden-eo ? reverse-engineered prompt

Build me a Euro Office plugin called CloudCIX Guiden that works inside Writer, Spreadsheet, and Presentation editors and lets users talk to an AI assistant from the plugin panel.

I want the user to be able to paste their CloudCIX API key, choose a simple action like ask, rewrite, summarize, translate, or draft new content, then send the current selection or the active document context to the assistant. Show a live preview while the response streams in, then let the user review the exact changes before applying them. For edits, keep it safe, only allow changes after validation, and do not expose an apply button if the response is incomplete or invalid.

Please make it work with the local Document Server plugin runtime, include the install and preflight helper scripts, and keep the key local unless the user chooses to remember it in the browser. If you need current docs for the office plugin runtime, look them up online first.
