+AI Usage Guideline
+##################
+
+.. gd_guidl:: Usage of Generative AI
+ :id: gd_guidl__ai_usage
+ :status: valid
+ :version: 1
+ :tags: process_management
+
+ This guideline defines how the
+ `Eclipse Generative AI Usage Guidelines `_,
+ made applicable by :need:`wp__policies`, are applied in the project. It applies to every
+ contribution to the project, independent of the repository and the kind of content,
+ including issues, pull requests and review comments.
+
+ The Eclipse guidelines remain the governing document. This guideline only makes them
+ concrete where the Eclipse guidelines leave a choice to the project.
+
+Responsibility
+==============
+
+#. The contributor (:need:`Contributor `) shall be responsible for every
+ change they submit, independent of whether it was created with the help of a generative AI
+ tool. The contributor shall have reviewed and understood every change and shall be able to
+ defend it in the review.
+#. The use of a generative AI tool shall not reduce the scope of the review, the acceptance
+ criteria or the automated checks that apply to a contribution.
+
+Disclosure
+==========
+
+#. The contributor shall disclose the use of a generative AI tool, if the AI contributed in a
+ way for which a human would be given credit.
+
+ No disclosure is required for trivial assistance, for example spelling and grammar
+ corrections, formatting, code completion of single statements or rote boilerplate that
+ the contributor modifies and supplements.
+
+#. The disclosure shall be given where the AI-assisted content is created:
+
+ - for changes in a repository, as ``Assisted-by:`` trailer in the message of every affected
+ commit;
+ - for issues, pull request descriptions and comments whose text is AI-assisted, as
+ ``Assisted-by:`` line in that text.
+
+#. The AI tool shall be identified in the following format, as complete as possible:
+
+ .. code-block:: text
+
+ Assisted-by: ()
+
+ Examples:
+
+ .. code-block:: text
+
+ Assisted-by: GitHub Copilot (GPT-4o-2024-08-06)
+ Assisted-by: Anthropic Claude Opus 5.5 (claude-opus-5-5)
+
+ If several AI tools were used, one ``Assisted-by:`` line per tool shall be given.
+
+#. A file that is largely or entirely AI-generated shall carry, in addition to the standard
+ copyright header of the project, an AI disclosure block directly below it:
+
+ .. code-block:: text

+ that the content is correct.
+ SPDX-License-Identifier: Apache-2.0 AND CC0-1.0
+ Assisted-by: ()
+
+ The copyright header of the project shall stay unchanged, so that the automated copyright
+ checks keep working.
+
+Review and Merge
+================
+
+#. Every merge into a repository of the project shall be approved by a human committer
+ (:need:`Committer `). AI agents or bots shall not push directly to protected
+ branches or merge pull requests.
+#. A committer may reject an AI-assisted contribution that they do not understand or are not
+ willing to maintain, or request that it is split into smaller pull requests.
+#. A committer shall request the missing disclosure, if a contribution appears to be
+ AI-assisted and is not disclosed.
+
+Functional Safety and Security
+==============================
+
+#. AI-assisted content in safety or security related work products shall follow the same
+ process, review and verification requirements as any other content. No additional rules
+ apply.
+#. AI tools used to create or verify work products shall be identified and evaluated like any
+ other tool according to Tool Management (:need:`wf__tool_evaluate_tool`). A qualification of
+ AI tools is not intended. Therefore the output of an AI tool shall not be used as work product
+ or verification evidence without human review.
