 Make sure you have added value based on your personal competency to your contributions. 
 Just taking some input, feeding it to an AI and posting the result is not of value to the project. 
 To preserve precious core developer capacity, we reserve the right to rigorously reject seemingly AI generated low-value contributions.
+Adapted from the [Linux Kernal](https://www.kernel.org/doc./html/next/process/coding-assistants.html):
+
+### Signed-off-by and Developer Certificate of Origin 
+
+AI agents MUST NOT add Signed-off-by tags. Only humans can legally certify the Developer Certificate of Origin (DCO). The human submitter is responsible for:
+
+  - Reviewing all AI-generated code
+  - Ensuring compliance with licensing requirements
+  - Adding their own Signed-off-by tag to certify the DCO
+  - Taking full responsibility for the contribution
+  
+See [Signing your work](#signing-your-work) for more information.
+
+
+### Attribution
+
+When AI tools contribute to development, proper attribution helps track the evolving role of AI in the development process. Contributions should include an Assisted-by tag in the commit message with the following format:
+
+```
+Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]
+```
+
+Where:
+
+  - `AGENT_NAME` is the name of the AI tool or framework
+  - `MODEL_VERSION` is the specific model version used
+  - `[TOOL1] [TOOL2]` are optional specialized analysis tools used (e.g., coccinelle, sparse, smatch, clang-tidy)
+
+Basic development tools (git, gcc, make, editors) should not be listed.
+
+Example:
+
+```
+Assisted-by: Claude:claude-3-opus coccinelle sparse
+```
