    return new AIPluginResult(
        new FileNotFoundException($"Pipeline path not found: {pipelinePath}"),
        "Pipeline path not found"
    );
}

2.3 Security Implementation

  • Input sanitization with regex patterns for secret detection

{
    @"(?i)(password|pwd|pass|secret|token|key|api[-_]?key)[\s]*[:=][\s]*[""']?[a-zA-Z0-9+/]{8,}[""']?",
    @"(?i)ghp_[a-zA-Z0-9]{36}",  // GitHub personal access token
