+# AI Coding Assistants
+
+This document provides guidance for AI tools and developers using AI assistance when contributing to `spyrmsd`.
+
+AI tools helping with `spyrmsd` development should follow the standard development process.
+
+## Licensing and Legal Requirements
+
+All contributions must comply with the `spyrmsd`'s licensing requirements:
+
+* All code must be compatible with the MIT license
+* Use appropriate SPDX license identifiers
+
+
+## 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
+
+## Attribution
+
+When AI tools contribute to `spyrmsd` development, proper attribution helps track the evolving role of AI in the development process. Contributions should include an Assisted-by tag in 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, and
+`[TOOL1] [TOOL2]` are optional specialized analysis tools used.
+Basic development tools (git, gcc, make, editors) should not be listed.
