-/// ## What it does
-/// Checks for Airflow function calls that will raise a runtime error in Airflow 3.0
-/// due to function signature changes, such as functions that changed to accept only
-/// keyword arguments, parameter reordering, or parameter type changes.
-///
-/// ## Why is this bad?
-/// Airflow 3.0 introduces changes to function signatures. Code that
-/// worked in Airflow 2.x will raise a runtime error if not updated in Airflow
-/// 3.0.
-///
-/// ## Example
-/// ```python
-/// from airflow.lineage.hook import HookLineageCollector
-///
-/// collector = HookLineageCollector()
-/// # Passing positional arguments will raise a runtime error in Airflow 3.0
-/// collector.create_asset("s3://bucket/key")
-/// ```
-///
-/// Use instead:
-/// ```python
-/// from airflow.lineage.hook import HookLineageCollector
-///
-/// collector = HookLineageCollector()
-/// # Passing arguments as keyword arguments instead of positional arguments
-/// collector.create_asset(uri="s3://bucket/key")
-/// ```
