# 3. Symbol overview of changed files
serena.get_symbols_overview(relative_path="changed/file")

# 4. Focus on changed functions
serena.find_symbol(name_path="ChangedClass/method", include_body=True)

# 5. Check impact scope
serena.find_referencing_symbols(name_path="ChangedClass/method")

# 6. Framework best practices
context7.get-library-docs("<framework>", topic="security")
