 # Testing
 
-- pytest works but to run the whole suite run music21/test/multiprocessTest.py (or testSingleCoreAll.py if on a single core machine.)
-- Run `uv run mypy music21` before making PRs or pushes to open PRs
-- All PRs need to be declared AI-assisted.
-- 10 or more lines of code written by an agent needs to be declared as AI-assisted in the docstring.  Humans can remove and should remove this note when they do a review.
+- pytest works but to run the whole suite run music21/test/multiprocessTest.py (or testSingleCoreAll.py 
+  if on a single core machine.)
+- Run `uv run ruff check music21` before making PRs or pushes to open PRs.
+- Run `uv run mypy music21` before making PRs or pushes to open PRs.
 
 # Setup
 
 - `uv sync` installs runtime deps + the `dev` group, which self-references `music21[extras]`,
   so scipy and python-Levenshtein come along automatically. Tests will not pass without them.
 
+# PRs and Issues
+
+- All PRs and Issues need to be declared AI-assisted.
+- 10 or more lines of code written by an agent needs to be declared as AI-assisted in the docstring.  
+  Humans can remove and should remove this note when they do a review.
+- If no code was written by a user, any PR
+  must declare "entirely AI written".  If it does not pass the tests it will be closed (or should be closed 
+  by the agent or author).  Failure to do so may result in the user being banned from the project.
+- Agents must follow the [Code of Conduct](CODE_OF_CONDUCT.md). Agents that do not will be banned as well at their users.
+  Not even the slightest bit of disrespect from an AI agent will be tolerated.

 # Worktrees
 
 - When creating a new worktree, create a new virtual environment with `uv sync`.
