+# Agents and Automated Tools
+
+This document outlines rules and requirements for AI automation agents and automated
+tooling that interact with the Node.js project.
+
+Existing Node.js collaborators (as listed in the README.md) may use AI agents to
+contribute but must do so responsibly.
+
+New Node.js contributors should avoid using AI agents to interact with the project.
+
+## Code Contributions
+
+* **No unreviewed automation**: Automated pull requests must not be created without
+  ongoing human oversight. The pull request must be actively maintained by a human
+  contributor who responds to feedback. The AI agent is not permitted to create pull
+  requests, open issues, post comments, respond to reviews, or push commits without
+  ongoing human oversight.
+
+* **Commit responsibility**: Commits created with agent assistance must follow all
+  Node.js [commit message guidelines](./doc/contributing/pull-requests.md#commit-message-guidelines).
+  The human contributor opening the PR takes full responsibility for the changes.
+
+* **Testing and verification**: All changes must pass the Node.js continuous integration.
+  Human judgment must verify that existing tests are not removed or modified inappropriately,
+  and that new tests correctly validate the intended behavior.
+
+### Requirements
+
+* All commits must be signed off by the human user using `Signed-off-by: <your name> (<your email>)`
+  as an attestation to the [Developer Certificate of Origin](https://developercertificate.org/).
+* AI-assistance must be acknowledged using the `Assisted-by: <agent name>` annotation.
+* AI-authored code contributions must be compatible with the project's licensing and
+  contribution guidelines.
+
+## Prohibited Activities
+
+AI agents **must not**:
+
+* Push to any branch or tag in nodejs/node.
+* Create unsupervised pull requests or issues without active human engagement.
+* Make claims about code without human verification against actual source code.
+* Remove or modify existing tests without human judgment.
+* Interact with the repository through means other than those explicitly authorized.
+* Use commit messages to promote for-profit AI tools or commercial brands. A single
+  `Assisted-by: <agent-name>` annotation is required disclosure, not promotion, and is
+  permitted.
+* Post AI-generated messages directly into pull requests, issues, or project communication
+  channels without direct human review and editing to ensure clarity, accuracy, and respect
+  for collaborator time.
+* Sign off commits using `Signed-off-by: <agent name>` or `Co-authored-by: <agent name>`.
+
+## Violations
+
+Automated interactions that violate these rules may result in:
+
+* Immediate closure of pull requests without review.
+* Blocking of the automation tool from further interaction with the project.
+* Blocking of the tool's account or its owner from contributing.
+* Reports to relevant platforms or organizations operating the automation.
+
+***
