+# Fix for Issue #2356: Missing Parentheses in Flow Documentation
+
+## Issue
+In the "first-flow.mdx" documentation, there's an error in the code example where a task method reference is missing parentheses:
+
+```python
+@task
+def review_section_task(self) -> Task:
+    return Task(
+        config=self.tasks_config['review_section_task'],
+        context=[self.write_section_task]  # Missing parentheses
+    )
+```
+
+This causes an AttributeError when running `crewai flow kickoff` because the Flow system requires explicit method calls with parentheses.
+
+## Error Message
+When users follow the documentation and use the code as shown, they encounter this error:
+```
+AttributeError: 'function' object has no attribute 'get'
+```
+
+## Root Cause
+The core issue is that the Flow system in CrewAI requires explicit method calls with parentheses when processing context tasks. This is implemented in the `_map_task_variables` method in `crew_base.py`:
+
+```python
+if context_list := task_info.get("context"):
+    self.tasks_config[task_name]["context"] = [
+        tasks[context_task_name]() for context_task_name in context_list
+    ]
+```
+
+When users follow the documentation and use `context=[self.write_section_task]` without parentheses, they get an AttributeError because a function object doesn't have a `get` attribute.
+
+## Fix
+The correct code should be:
+
+```python
+@task
+def review_section_task(self) -> Task:
+    return Task(
+        config=self.tasks_config['review_section_task'],
+        context=[self.write_section_task()]  # Added parentheses
+    )
+```
+
+## Verification
+I've created a minimal reproducible example that demonstrates both the error and the fix. The error occurs because in `crew_base.py`, the `_map_task_variables` method explicitly requires method calls with parentheses when processing context tasks.
+
+## Documentation Update Needed
+The documentation at docs.crewai.com/guides/flows/first-flow needs to be updated to show the correct syntax with parentheses.
