 ## Writing

-- Lists themselves are acceptable
+Use the elements-of-style writing skill for documentation, commit
+messages, PR descriptions, and user-facing text. Apply it before
+considering prose complete.
+
+Style rules: Avoid the "**bold**: explanation" pattern in lists. Use
+plain text or structured prose instead.
+
+Examples to avoid:
+- **Option A**: explanation text here
+- **Foo**: description follows
 
-For detailed writing assistance, invoke the `writing` skill.
+Acceptable alternatives:
+- Use plain list items without bold labels
+- Use prose paragraphs for explanations
+- Use tables for multi-column comparisons
+- Bold text is acceptable in headers and inline emphasis

 - Avoid references to unavailable conversations or artifacts
