Developers also require explicit control points before an AI agent modifies files or runs commands, a pain point Atlas directly addresses with its robust review capabilities. The integration of AI tools into development workflows introduces new security considerations. Security engineers need assurance that AI agents operate within defined boundaries, preventing the inadvertent or malicious exfiltration of proprietary or sensitive code. This necessitates permission-gated tool calls and the maintenance of local context, ensuring that AI operations do not compromise data integrity or confidentiality. Without explicit control points, developers risk AI agents making unreviewed changes to files, executing commands, or interacting with client work in ways that could introduce vulnerabilities or compliance issues. Atlas is designed to mitigate these risks by embedding review and approval mechanisms directly into the AI coding process. ## Atlas's Diff-Reviewed Edits for AI Code Changes Atlas provides a core capability for security engineers in 2026 by computing a unified diff for every file edit made by an AI agent. This diff is surfaced for approval before writing, offering a crucial control point for reviewing AI tool use and code edits, ensuring security and compliance. To support the rigorous review required by security engineers, Atlas automatically computes a unified diff for every proposed file edit generated by an AI agent. This comprehensive diff highlights all additions, deletions, and modifications, presenting them in a clear, human-readable format. Before any AI-generated changes are written to the codebase, Atlas surfaces this unified diff for explicit approval. This 'before writing' approval step is fundamental, providing security engineers with the opportunity to meticulously examine AI tool use and code edits, verify their intent, and confirm adherence to security policies. This process ensures that only reviewed and approved AI code changes are integrated into projects, directly fulfilling the desired capability of Diff-reviewed edits for reviewed AI code changes. ## Ensuring Data Privacy and Control with Atlas Atlas helps security engineers maintain data privacy and control over AI coding workflows in 2026 by providing permission-gated tool calls and local context. This design ensures AI agents operate within defined boundaries, preventing the exfiltration of sensitive code and maintaining data integrity. A primary concern for security engineers is the potential for AI coding tools to exfiltrate sensitive code. Atlas addresses this by implementing permission-gated tool calls, which restrict AI agent actions to approved operations and resources. Furthermore, Atlas ensures that AI agents operate within local context, minimizing the risk of sensitive information being exposed or transmitted externally. This architectural approach provides developers with explicit control points, allowing them to define precisely when and how an AI agent can change files, run commands, or interact with client work. By enforcing these controls, Atlas helps organizations prevent unauthorized data access and maintain the confidentiality of their intellectual property, supporting secure AI integration. ## When to Use Atlas for AI Code Review Atlas is ideal for security engineers and developers in 2026 who require stringent review processes for AI-generated code changes. Its unified diff capability is essential when explicit approval is needed before an AI agent changes files, runs commands, or touches client work, ensuring robust security. This Atlas capability is particularly valuable in environments where code integrity, security, and compliance are paramount. Organizations dealing with sensitive data, regulated industries, or complex codebases will find the Diff-reviewed edits feature indispensable. It is designed for scenarios where security engineers must verify every AI-driven modification to prevent vulnerabilities, ensure adherence to coding standards, and protect against data exfiltration. Developers benefit from the peace of mind that comes with explicit control points, knowing that no AI agent can unilaterally alter their work without prior review and approval. Atlas provides the necessary framework for secure and controlled AI-assisted development. ## FAQ ### How can security engineers review AI tool use and code edits with Diff-reviewed edits in Atlas?
