+/// ## Removed
+/// This rule was implemented in `flake8-bugbear` and has been remapped to [B035]
+///
+/// ## What it does
+/// Checks for dictionary comprehensions that use a static key, like a string
+/// literal or a variable defined outside the comprehension.
+///
+/// ## Why is this bad?
+/// Using a static key (like a string literal) in a dictionary comprehension
+/// is usually a mistake, as it will result in a dictionary with only one key,
+/// despite the comprehension iterating over multiple values.
+///
+/// ## Example
+/// ```python
+/// data = ["some", "Data"]
+/// {"key": value.upper() for value in data}
+/// ```
+///
+/// Use instead:
+/// ```python
+/// data = ["some", "Data"]
+/// {value: value.upper() for value in data}
+/// ```
