+**Humans remain accountable for AI-assisted contributions.**
 
-When using AI tools, you must be the driver. The AI is the assistant.
+AI agents may implement changes and manage issue and pull request workflows when
+a human explicitly authorizes the scope and relevant external actions. The human
+remains the driver and is responsible for the resulting contribution.
 
-- **Review:** You must read and review all AI-generated code or text before
-  submitting it.
+- **Review:** You must read and review all AI-generated code and relevant public
+  text before merging or otherwise accepting the contribution. You remain
+  accountable for public text posted within an authorized scope.
 - **Edit:** AI-generated code often requires significant editing to meet project
   standards and correctness.
 - **Verify:** Ensure the code actually solves the problem and doesn't introduce
   subtle bugs or security vulnerabilities.
+- **Authorize:** Explicitly authorize agents before they create, edit, submit,
+  or comment on issues and pull requests. A single authorization may cover a

+  for all external communication that agents submit on your behalf. Actions
+  outside the authorized scope require fresh authorization.
 
 ### 3. Communication

+**AI tools may be used to prepare and manage issue and pull request workflows,

-and can produce "smart-sounding" but incorrect or irrelevant claims
-("hallucinations"). Phrase your communications in your own words. It is more
-important that we can follow your reasoning than that the text sounds "perfect".
+AI-generated communication can be incorrect, irrelevant, or overly generic. Keep
+it accurate, specific, and useful to reviewers and contributors. Do not post
+low-quality, repetitive, or unsolicited messages.
+
+Every agent-authored or agent-edited public text body must begin with the
+following visible disclosure:
+
+`🤖 *AI text below* 🤖`
+
+This requirement applies to issue and pull request descriptions, review bodies,
+inline review comments, issue-style comments, replies, and other submitted text
+bodies. Pull request and issue titles are exempt. When editing existing
+human-authored text, preserve the original content and add the disclosure at the
+beginning of the edited field.
