+
+/// ## What it does
+/// Checks for implicitly concatenated strings inside list, tuple, and set literals.
+///
+/// ## Why is this bad?
+/// In collection literals, implicit string concatenation is often the result of
+/// a missing comma between elements, which can silently merge items together.
+///
+/// ## Example
+/// ```python
+/// facts = (
+///     "Lobsters have blue blood.",
+///     "The liver is the only human organ that can fully regenerate itself.",
+///     "Clarinets are made almost entirely out of wood from the mpingo tree."
+///     "In 1971, astronaut Alan Shepard played golf on the moon.",
+/// )
+/// ```
+///
+/// Instead, you likely intended:
+/// ```python
+/// facts = (
+///     "Lobsters have blue blood.",
+///     "The liver is the only human organ that can fully regenerate itself.",
+///     "Clarinets are made almost entirely out of wood from the mpingo tree.",
+///     "In 1971, astronaut Alan Shepard played golf on the moon.",
+/// )
+/// ```
+///
+/// If the concatenation is intentional, wrap it in parentheses to make it
+/// explicit:
+/// ```python
+/// facts = (
+///     "Lobsters have blue blood.",
+///     "The liver is the only human organ that can fully regenerate itself.",
+///     (
+///         "Clarinets are made almost entirely out of wood from the mpingo tree."
+///         "In 1971, astronaut Alan Shepard played golf on the moon."
+///     ),
+/// )
+/// ```
+///
+/// ## Fix safety
+/// The fix is safe in that it does not change the semantics of your code.
+/// However, the issue is that you may often want to change semantics
+/// by adding a missing comma.
