 ## Code Style
 
 - **Comments**: Describe the final code state, not what changed. Avoid "changed X to Y" or "added this because..." comments.
-- **Git commits/PRs**: No emoji, no "Generated by..." footers, no co-author boilerplate.
 - **Type annotations**: Fix type errors properly instead of using `# type: ignore`. Prefer:
   - `@overload` decorators for functions with different return types based on input
   - `assert` statements to narrow types after None checks

   - `np.atleast_1d()` or similar to guarantee array returns from numpy functions
   - Only use `# type: ignore` as a last resort for genuine type checker limitations (e.g., numpy's `ArrayLike` being too broad)
 
-## Shell Command Style
-
-- **Do NOT use compound `cd` commands** like `cd foo && git status` or `cd foo && pytest`. Compound commands that cross directories require explicit user approval and slow things down. Instead, issue a standalone `cd foo` command first, then run the action as a separate command. The Bash tool's working directory persists between calls.

 ## Testing Guidelines
 
 **When CI tests fail, fix them.** Don't waste time analyzing whether failures are "related to your changes" — just fix all failing tests. The goal is a green CI, not attribution.
