+Contributions made by Large Language Models are politely declined.
-## Regarding use of Agents
-
-`wavinfo` is an open-source project that is offered free for no commerical gain, and 
-is developed and maintained for educational and creative reasons.
-
-If you use an agent or LLM to produce code for it you are missing out on the benefits 
-of contributing to an open-source project, particularly community, collaboration with 
-other developers and designers, and being able to learn and experiment without the 
-burden of deadlines or worrying about business cases or profits.
-
-This project is supposed to be fun, do not let machines have fun for you.
-
-We can't prevent you from using LLMs to contribute to this project but we ask you 
-abide by the following eitiquette when doing so:
-
-* All communication with the maintainers must be written by a human in their own
-  voice. Never use an LLM to craft thread comments, discussion posts, issues, emails
-  or other correspondence with other developers or the maintainers. 
-* PRs must be submitted by a person. Do not allow an agent to submit its own PRs to
-  this project.
-* Especially if you are a new contributor to this project, please submit only one PR
-  at a time and please restrict the subject matter of the PR to a specific unit,
-  module or tool. All submissions have to be reviewed and understood by the
-  maintainers before they can be merged.
-
-Obviously we can't verify if you follow all of these rules but certain telltale 
-traits of LLM-predicted text or code will raise a flag: lack of brevity in 
-descriptions or code comments, large amounts of text describing your process or 
-steps that add little to understanding the changes you've made, use of an 
-obsequious tone or being excessively accomodating, immediately doing requests 
-without further discussion or clarifications.
