+Seed Go Plugin: file-module-size
+
+Flags Python files that exceed the recommended size limit.
+
+Seed's internal standard: files should be <= 400 lines of code (excluding
+blank lines, comments, and docstrings).
+
+Large files are a code smell indicating:
+- Too many responsibilities (SRP violation)
+- Difficult to navigate and understand
+- Hard to test thoroughly
+- Likely candidates for refactoring
+
+This is a WARNING, not an ERROR, because sometimes large files are unavoidable
+or refactoring isn't immediately feasible.
