+Name transforms
+---------------
+
+Generated Python names for functions, methods, and attributes can be configured
+with ``name_transform``. Explicit ``rename`` entries still take precedence, and
+YAML ``strip_prefixes`` is applied before the transform.
+
+Configuration precedence is:
+
+#. YAML ``name_transform``
+#. ``[tool.semiwrap.extension_modules."pkg.name"].name_transform``
+#. ``[tool.semiwrap].name_transform``
+#. ``default``
+
+Built-ins are ``default``, ``camelCase``, ``snake_case``, and ``PascalCase``.
+Custom transforms use ``custom: package.name:function`` and receive
+``(name: str, kind: str)`` where kind is ``function``, ``method``, or
+``attribute``.
+
+Example::
+
+   name_transform: snake_case
+   strip_prefixes:
+   - SW_
+
+Name transforms do not apply to classes, enums, enum values, template instance
+names, or parameter names.
