Dealing with Poor Quality AI-Generated Code

The proliferation of AI-powered coding assistants has fundamentally altered the software development landscape. These tools promise to dramatically increase developer productivity, accelerate timelines, and streamline the creation of complex applications. The data supports this promise; according to recent studies, development teams see coding productivity rise by over 40% with the adoption of AI tools. However, this new paradigm is not without its challenges. The code generated by these large language models (LLMs) is often a “black box” output—it can appear functional at first glance but may harbor subtle bugs, security vulnerabilities, and performance inefficiencies.

Engineering leaders are feeling the pressure. Executives demand faster innovation through AI, while development teams often find themselves bogged down, fixing the very code that was supposed to make them faster. This creates a critical bottleneck where the potential productivity gains are nullified by the time spent debugging and refactoring suboptimal code. The key to unlocking the true power of AI in development lies not in blindly accepting its output, but in establishing a robust framework for validating, correcting, and integrating it.

This article provides a comprehensive guide for developers and engineering managers on how to deal with poor-quality AI-generated code. We will explore techniques for identifying problematic code, strategies for correcting it effectively, and the importance of a human-in-the-loop approach. Furthermore, we will discuss how partnering with an experienced AI development agency like MetaCTO can help organizations navigate these complexities, turning AI from a source of potential chaos into a reliable foundation for growth and innovation.

The Double-Edged Sword of AI Code Generation

AI coding assistants represent a significant leap forward in developer tooling, but like any powerful technology, they come with both substantial benefits and inherent risks. Understanding this duality is the first step toward leveraging them effectively and responsibly.

The Upside: A Catalyst for Productivity and Innovation

The advantages of integrating AI into the coding process are compelling and well-documented. When used correctly, these tools can serve as a powerful force multiplier for any engineering team.

  • Accelerated Development Cycles: The most immediate benefit is a dramatic reduction in the time it takes to write code. AI assistants excel at generating boilerplate, scaffolding new components, and writing routine functions. Drawing upon the proficiency offered by AI experts and tools can significantly shorten product-to-market timelines, providing businesses with a strategic advantage over their competitors.
  • Enhanced Focus on High-Value Problems: By automating the more mundane aspects of coding, AI frees up developers to concentrate on what truly matters: complex problem-solving, system architecture, and core business logic. This shift allows organizations to focus more intently on core business objectives, which boosts overall productivity and innovation.
  • Democratization of Knowledge: AI assistants can act as an on-demand tutor, helping developers learn new programming languages, explore unfamiliar frameworks, or understand complex algorithms by providing instant examples and explanations. This facilitates continuous learning and helps bridge skill gaps within a team.
  • Improved Code Consistency: When guided by well-defined prompts and style guides, AI tools can help enforce coding standards across a team, leading to a more consistent and maintainable codebase.

The Downside: Hidden Risks and Quality Concerns

Despite the immense potential, the code produced by AI is not infallible. The underlying models are probabilistic systems trained on vast datasets of public code, which includes both high-quality examples and flawed ones. This can lead to a range of serious issues that, if left unchecked, can compromise an entire project.

  • Subtle and Insidious Bugs: AI can generate code that compiles and appears to work correctly for common cases but fails spectacularly on edge cases. These logical flaws can be incredibly difficult to detect during a cursory review and may only surface in a production environment, leading to critical failures.
  • Security Vulnerabilities: AI models may inadvertently reproduce common security anti-patterns found in their training data, such as SQL injection vulnerabilities, improper error handling, or the use of insecure cryptographic functions. Without rigorous security scanning, AI-generated code can become a significant liability.
  • Performance Inefficiencies: The primary goal of a code-generating AI is to produce a functional solution, not necessarily the most performant one. The resulting code may be algorithmically inefficient, consume excessive memory, or fail to leverage platform-specific optimizations, leading to slow and costly applications.
  • API and Function “Hallucinations”: In some cases, LLMs will confidently “hallucinate” functions, libraries, or API endpoints that do not exist. A developer who trusts this output without verification will waste valuable time debugging code that was never viable.
  • Outdated Practices and Deprecated Code: The knowledge of an AI model is frozen at the time of its last training run. This means it may generate code that uses deprecated libraries, outdated programming idioms, or patterns that are no longer considered best practice, leading to technical debt from day one.
  • Lack of Project-Specific Context: A general-purpose AI model has no intrinsic understanding of your application’s unique architecture, business rules, or long-term goals. Its suggestions are often generic and may not align with the established patterns and constraints of your codebase, requiring significant refactoring to integrate properly.

Identifying Problematic AI-Generated Code

Treating AI-generated code as a finished product is a recipe for disaster. Instead, it should be viewed as a first draft submitted by a talented but inexperienced team member—one that requires rigorous scrutiny. Implementing a multi-layered validation strategy is essential to catch flaws before they reach production.

1. Mandate Rigorous, Human-Led Code Reviews

The single most important line of defense against poor-quality AI code is the experienced human developer. Code reviews must become even more stringent, not less, in the age of AI.

  • Assume Nothing: Reviewers should approach every line of AI-generated code with healthy skepticism. The focus should be on verifying not just the syntax, but the underlying logic, adherence to architectural patterns, and potential for unintended side effects.
  • Check for “The Why”: The AI provides the “what” (the code), but the reviewer must validate “the why.” Does this code solve the problem in the most effective way? Does it align with the project’s long-term goals? Is it maintainable and easy for other developers to understand?
  • Leverage AI for the Review Process: The same technology that generates code can also assist in reviewing it. Modern code review tools are beginning to integrate AI to summarize changes, suggest improvements, and spot potential issues, which can help focus the human reviewer’s attention on the most critical areas.

2. Implement a Comprehensive and Automated Testing Suite

If code reviews are the first line of defense, a robust testing strategy is the second. Automated tests are critical for systematically validating the behavior of AI-generated code under a wide variety of conditions.

  • Unit Testing: Every function or method generated by AI should be covered by unit tests that validate its correctness, especially for edge cases. Ask the AI to generate unit tests for its own code; this often reveals flaws in the original implementation.
  • Integration Testing: Because AI lacks deep contextual understanding, it’s crucial to test how its generated code interacts with other parts of the system. Integration tests verify that different components work together as expected and that no existing functionality has been broken.
  • End-to-End (E2E) Testing: E2E tests simulate real user workflows to ensure that the application behaves correctly from the user’s perspective. This is the final check to confirm that AI-generated features are not only functionally correct but also deliver the intended user experience.
  • AI-Powered Testing Tools: An emerging class of AI-powered testing platforms can accelerate test creation and improve coverage. These tools analyze an application to automatically generate test cases, helping teams achieve higher quality with less manual effort. Studies show that AI can increase test coverage by over 50%.

3. Integrate Static Analysis and Security Scanning

Automated analysis tools are indispensable for catching common errors and vulnerabilities that might be missed by human reviewers. These tools should be integrated directly into your Continuous Integration/Continuous Deployment (CI/CD) pipeline to provide immediate feedback.

  • Linters and Static Analyzers: These tools enforce coding style, identify potential bugs, and flag “code smells” without ever running the code. They are excellent at ensuring consistency and catching common mistakes in AI-generated output.
  • Static Application Security Testing (SAST): SAST tools scan source code to identify known security vulnerabilities, such as those on the OWASP Top Ten list. This is a non-negotiable step for any code generated by an external system like an AI.
  • Performance Profiling: Before accepting a complex algorithm or data processing function from an AI, run it through a performance profiler. This will identify any computational bottlenecks or memory inefficiencies that could degrade application performance under load.

Correcting and Refining AI-Generated Code

Identifying flaws is only half the battle; the next step is to correct and refine the code into a production-ready asset. This is a collaborative process between the developer and the AI, where human expertise guides the model’s powerful generative capabilities.

1. Master the Art of Iterative Prompting

The quality of the AI’s output is directly proportional to the quality of the input. A vague, one-shot prompt will likely yield a generic, flawed response. Developers must learn to become “AI whisperers,” guiding the model toward the desired outcome through a series of increasingly specific prompts.

  • Provide Context: Include code snippets from your existing project, describe the desired architectural patterns, and specify the versions of libraries and frameworks to be used.
  • Set Constraints: Instruct the AI on what not to do. For example: “Generate a Python function to parse this JSON, but do not use any external libraries” or “Ensure the solution is O(n log n) complexity.”
  • Request Alternatives and Refinements: If the first response isn’t quite right, don’t start from scratch. Ask the AI to refine its own code: “That’s a good start, but can you refactor it to be more modular?” or “Please add comprehensive error handling for network failures.”

2. Embrace Human-in-the-Loop Refactoring

The most effective workflow treats the AI’s output not as a final solution, but as an advanced starting point. An experienced developer should take this initial draft and apply their deep domain knowledge and expertise to refactor it. This human touch is irreplaceable for several reasons:

  • Ensuring Architectural Cohesion: A developer can ensure the new code seamlessly integrates with the existing system architecture, respecting established design patterns and conventions.
  • Applying Business Logic Nuances: The AI may not grasp the subtle business rules and domain-specific knowledge that a human expert possesses. Refactoring allows these critical details to be correctly implemented.
  • Optimizing for Readability and Maintainability: A developer can refactor the code to improve variable names, add clarifying comments, and structure the logic in a way that will be easy for other team members to understand and maintain in the future.

3. Build Institutional Knowledge

As your team encounters common failure modes and successful correction patterns, document them. Create an internal set of best practices for prompting, a checklist for reviewing AI-generated code, and a library of well-vetted, high-quality prompts for recurring tasks. This turns individual learning into a shared asset that elevates the entire team’s ability to work with AI effectively.
