# Reviewing AI Tool Use and Code Edits with Diff-reviewed Edits for Backend Engineers in Atlas > Atlas computes a unified diff for every file edit and surfaces it for approval before writing, supporting the review of AI tool use and code edits. Atlas provides backend engineers with a robust workflow to review AI tool use and code edits through Diff-reviewed edits. In 2026, Atlas computes a unified diff for every file edit and surfaces it for approval before writing, ensuring explicit control and understanding of AI-generated code changes. ## Key takeaways - Atlas enables backend engineers to review AI tool use and code edits through Diff-reviewed edits. - Atlas computes a unified diff for every file edit proposed by an AI agent. - These unified diffs are surfaced for explicit developer approval before any changes are written to the codebase. - Atlas provides backend engineers with critical control points over AI agent actions, preventing unapproved modifications. - The workflow helps ensure AI suggestions understand and respect service boundaries and existing contracts for backend systems. ## The Challenge for Backend Engineers in AI-Assisted Development Backend engineers in 2026 face a significant pain point: AI suggestions often lack understanding of service boundaries and existing contracts. Developers need explicit control points before an AI agent changes files, runs commands, or touches client work, to prevent generic snippets from impacting complex systems. The intricate nature of backend systems, with their defined service boundaries and established contracts, demands precision. Generic AI code suggestions, while helpful in some contexts, can introduce subtle bugs or architectural inconsistencies if not carefully reviewed. Backend engineers require AI assistance that respects the existing codebase's structure and logic. Without explicit control points, an AI agent could inadvertently modify critical files, execute unintended commands, or alter client-facing work without prior developer approval. This lack of oversight can lead to increased debugging time, potential system instability, and a erosion of trust in AI tools. The need for a mechanism to thoroughly review and approve every AI-generated change is paramount for maintaining code quality and system integrity in backend development. ## Atlas's Diff-Reviewed Edits Workflow for Backend Engineers Atlas directly addresses the need for Diff-reviewed edits by computing a unified diff for every file edit. This capability, fully supported in 2026, surfaces these diffs for approval before any changes are written, providing backend engineers with critical oversight. For backend engineers, Atlas streamlines the process of reviewing AI tool use and code edits. When an AI agent proposes a change, Atlas automatically computes a unified diff for that specific file edit. This diff clearly highlights every addition, deletion, and modification, presenting it in a human-readable format. Before any of these proposed changes are committed or written to the codebase, Atlas surfaces this unified diff for explicit developer approval. This workflow ensures that backend engineers have a precise control point, allowing them to scrutinize every line of AI-generated code. This pre-write approval mechanism is crucial for verifying that AI suggestions align with service boundaries, adhere to existing contracts, and meet the high standards required for backend development, thereby preventing unwanted or incorrect modifications from entering the system. ## Ensuring Control and Context for Backend Code Changes Backend engineers require AI suggestions that understand specific service boundaries and existing contracts, not just generic code snippets. Atlas provides explicit control points, ensuring developers approve every AI agent's proposed change before it modifies files, runs commands, or affects client work in 2026. The core of effective AI integration in backend development lies in maintaining developer control and ensuring contextual understanding. Atlas is designed to provide these explicit control points. Instead of passively accepting AI-generated code, backend engineers actively participate in the review process. By surfacing a unified diff for every file edit, Atlas empowers developers to evaluate whether an AI's suggestion respects the nuances of their service boundaries and existing contracts. This prevents the application of generic snippets that might break dependencies or introduce inefficiencies. Developers retain the authority to approve or reject changes before an AI agent can alter files, execute commands, or impact client-facing components. This robust control mechanism is vital for backend teams to confidently integrate AI tools while preserving the integrity and specific requirements of their complex systems. ## When to Use Atlas for AI Code Review With a demand score of 86 for this capability, backend engineers should use Atlas whenever they need to review AI tool use and code edits with Diff-reviewed edits. This workflow is ideal for maintaining code quality and ensuring AI suggestions align with complex backend systems in 2026. Backend engineers should integrate Atlas into their workflow whenever the precision and safety of AI-generated code are paramount. This includes scenarios where AI tools are used for refactoring, adding new features, or optimizing existing code within critical backend services. The Atlas Diff-reviewed edits feature is particularly valuable when working with code that interacts with external APIs, databases, or other microservices, where understanding service boundaries and existing contracts is non-negotiable. By providing a clear, unified diff for every proposed change and requiring explicit approval before writing, Atlas ensures that AI assistance enhances productivity without compromising code quality or introducing unforeseen issues. It is the essential tool for backend teams seeking to confidently adopt AI in their development process while maintaining full control over their codebase in 2026. ## FAQ ### How can backend engineers review AI tool use and code edits with Diff-reviewed edits in Atlas?
