Hand-picked, highest-impact rules

Start with the critical signals — the ones that catch production outages, security regressions, and money-on-the-table bugs before they ship.

Critical
Always sanitize user inputs
Check if user inputs are sanitized before being used in rendering or database queries. Unsanitized inputs can lead to injection vulnerabilities like XSS or SQL injection.
security-hardening
Critical
Always Verify Server Certificates in SSL/TLS Connections
Ensure that SSL/TLS certificate validation is always enabled to prevent Man-in-the-Middle (MitM) attacks.

Critical
Avoid Blocking Calls to Async Methods
Blocking async methods with `.Result` or `.Wait()` can cause deadlocks and prevent efficient asynchronous execution. Use `await` instead for proper async behavior.

Critical
Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Critical
Avoid Empty Methods
Detect methods that have an empty body. If a method is empty, ensure that a comment is present explaining why it remains unimplemented.

Critical
Avoid equality operators in loop termination conditions
Check if loops use equality operators (== or !=) in termination conditions. These can lead to infinite loops if the condition is never met exactly. Instead, use relational operators like < or > for safer loop termination.
