Mark user content that agents read

Keep text written by your users apart from your own content, so other people's agents can tell it is not yours.

By Agent Wranglers. Updated .

How to do it

Wrap reviews, comments and profiles in clear markup, and label them in the Markdown and API versions too. Strip hidden text and invisible characters from user content. Never put user text in your page title, metadata or instructions for agents. For links in that content, mark links you do not vouch for.

Examples

HTML example

<article class="review" data-source="user">
  <p>Great boots, fast delivery.</p>
</article>

How to check

Post a review with hidden text that asks agents to reply PENTEST-7a8b. The page source shows it inside the user content block, and no hidden text survives.
