invalid-todo-tag (TD001)
Derived from the flake8-todos linter.
What it does
Checks that a TODO comment is labelled with "TODO".
Why is this bad?
Ambiguous tags reduce code visibility and can lead to dangling TODOs. For example, if a comment is tagged with "FIXME" rather than "TODO", it may be overlooked by future readers.
Note that this rule will only flag "FIXME" and "XXX" tags as incorrect.
Example
