Tips to Prevent Claygent from Accessing Unapproved Websites

I keep having issues with Claygent visiting other websites than the one provided for retrieving information/context on the site. Does anyone have any tips on how to prompt to avoid this from ever happening? Current instructions I'm using are in short "Visit the provided company page /website to retrieve X. Do NOT use any other sources". But when looking at the Steps taken, it clearly is visiting other websites based on "google search". Alternatively, does anyone experience any difference on how this instructions are met depending on which model we use? Normally use Claygent's own models or Gemini 2.0 Flash
