Reviewer Prompt

Always implement proper authentication checks and protect sensitive credentials throughout your codebase. This includes:

  1. Validate all authentication inputs properly to prevent panics and security vulnerabilities: ```rust // Bad: Will panic on short inputs if &authorization[0..7] != “Bearer “ { // … }

// Good: Safe parsing without panic risk if let Some(token) = authorization.strip_prefix(“Bearer “) { // Process token safely } else { return Err(tonic::Status::invalid_argument(“invalid authorization format”)); }


2. **Implement permission checks for all API endpoints**, even internal or testing ones:
```rust
// Always add permission checks to new endpoints
async fn your_api_endpoint(
    request: Request<Body>,
    _cancel: CancellationToken,
) -> Result<Response<Body>, ApiError> {
    // Add this check to prevent unauthorized access
    check_permissions(&request, None)?;
    
    // Rest of your endpoint logic
    // ...
}
  1. Redact sensitive information in logs to prevent credential exposure:
    // When logging URLs or other structures that might contain credentials
    match url::Url::parse(url) {
     Ok(mut url) => {
         if url.password().is_some() {
             let _ = url.set_password(Some("_redacted_"));
         }
         // Now safe to log
         info!("Using URL: {}", url);
     }
     // ...
    }
    

These practices prevent unauthorized access to sensitive endpoints, reduce risks of credential leakage, and improve the overall security posture of the system.
