FAQPage Schema
How do I perform an automated code review for security and maintainability issues?

Automated code review analyzes your project to identify security vulnerabilities, performance bottlenecks, and maintainability issues, providing structured, actionable fixes to increase code quality and reduce cycle time.

What is the best way to get architectural design consultation for a software project?

Design consultation proposes architectural improvements and evaluates trade-offs for scalable systems, delivering clear recommendations that help engineers make informed structural decisions during software development.

How does a sandboxed CLI workflow handle bug investigation safely?

A sandboxed CLI workflow handles bug investigation by running in a restricted, read-only environment, ensuring deterministic diagnosis of issues without risking unintended modifications to the underlying software project.

Can I analyze code in a read-only sandbox without modifying my project files?

Yes, you can analyze code in a read-only sandbox by executing explicit prompts against your project directory, which ensures the environment remains completely isolated and prevents any unintended file modifications.

Does AI-assisted code review provide deterministic and actionable output?

AI-assisted code review provides deterministic and actionable output by requiring explicit prompts, ensuring the analysis yields structured recommendations and clear fixes rather than ambiguous or unpredictable responses.

When do I need a sandboxed environment for bug investigation and wording review?

You need a sandboxed environment for bug investigation and wording review when running AI-assisted analysis on user-facing messages and documentation, ensuring safe execution without altering the live codebase.
