name: autofix-namespace description: Fixes 'not a member of namespace' errors by adding namespace qualifiers or using declarations.

Namespace Skill

Fixes C++ namespace-related compilation errors.

Detection Patterns

• 'X' is not a member of 'std'
• 'X' is not a member of 'namespace'
• 'X' was not declared in this scope (when namespace issue)

Strategy

1. Identify Symbol: Extract the symbol and expected namespace.
2. Add Qualifier: Prefix the symbol with namespace, or add using.

Instructions

Step 1: Parse Error

From: 'cout' is not a member of 'std' Symbol: cout, Namespace: std

Step 2: Common Fixes

Add namespace prefix:

Copy// Before
cout << "Hello";  // ERROR
// After
std::cout << "Hello";

Add using declaration:

Copy// At top of file or function
using std::cout;
// Or
using namespace std;  // Less recommended
