message: "'async' and 'await' should not be used as identifiers"

description: |
  Using async and await as identifiers is confusing and may cause
  conflicts with the async/await keywords. Use different names.

  ✅ FIX: Use descriptive names that don't conflict with keywords

  ```csharp
  bool isAsyncOperation = true;  // GOOD - descriptive
  ```

query: |
  (variable_declarator
    (identifier) @NAME (#match? @NAME "^(async|await)$"))
  (parameter
    (identifier) @NAME (#match? @NAME "^(async|await)$"))
  (property_declaration
    name: (identifier) @NAME (#match? @NAME "^(async|await)$"))

metavars:
  - NAME

examples:
  bad: |
    int async = 5;  // BAD - keyword as identifier
    void Method(int await) { }  // BAD

  good: |
    int asyncOperation = 5;  // GOOD - descriptive
    void Method(int waitTime) { }  // GOOD
