+# AI Usage Policy
+
+This project has strict rules for AI usage:
+
+* **The human-in-the-loop must fully understand all code.** If you
+can't explain what your changes do and how they interact with the
+greater system without the aid of AI tools, do not contribute
+those changes.
+
+* **Issues and discussions can use AI assistance but must have a full
+human-in-the-loop.** This means that any content generated with AI
+must have been reviewed *and edited* by a human before submission.
+The author must do their research and trim this down.
+
+* **No AI-generated media is allowed (textures, videos, audio, etc.).**
+Text and code are the only acceptable AI-generated content, per the
+other rules in this policy.
+
+* **Commit messages, PR descriptions must read in your own voice.**
+No AI-authored or AI co-authored commits, including Co-authored-by AI tags.
+
+* **Only contribute fixes for bugs you have personally hit in-game.**
+If you haven’t experienced or reproduced a bug firsthand, and don’t
+already know the relevant code well, don’t throw AI at it and forward it to us.
+Patches written for problems the author never actually experienced themselves
+tend to fix the wrong thing and/or produce another.
+
+* **The voice and intent of written content must be yours.**
+For documentation and especially quests, the tone and the point you're trying to make
+has to come from you, not an AI. Use AI to help with phrasing or cleanup if you like,
+but if the substance and voice aren't yours, don't contribute it.
+
+* **Bad AI use may be blocked.** People who produce bad contributions
+that are clearly AI (slop) may be blocked from making future contributions.
+We love to help junior developers learn and grow, but if you're interested
+in that, don't use AI and we'll help you. We're sorry that bad AI
+users have ruined this for you.
+
+
+## There are Humans Here
+
+Please remember that this project is maintained by humans.
+
+Every discussion, issue, and pull request is read and reviewed by
+humans (and sometimes machines, too). It is a boundary point at which
+people interact with each other and work is done. It is rude and
+disrespectful to approach this boundary with low-effort, unqualified
+work, since it puts the burden of validation on the maintainer.
+
+In a perfect world, AI would produce high-quality, accurate work
+every time. But today, that reality depends on the user of the AI.
+And today, many users of AI do not use it well. So, until that
+changes, we need to have strict rules to protect maintainers.
+
