Autopilot Mode (Copilot CLI): Autopilot mode, when enabled with all permissions, allows the Copilot CLI to run its various internal commands, including Git operations required for the `review` process, without pausing for user confirmation at each step. This significantly streamlines and accelerates the overall workflow, especially for operations involving multiple sequential commands. For the listener, it means a faster, more fluid AI interaction but also implies a higher degree of trust in the AI's autonomous actions.
Focus Style on CTA Button: A focus style is a crucial accessibility feature, ensuring that users navigating with a keyboard (rather than a mouse) can clearly see which interactive element, like a Call to Action (CTA) button, currently has focus. The `review` command's ability to identify and automatically fix a missing focus style highlights its capability to improve not just code quality but also user experience and accessibility. For the listener, this demonstrates how AI can proactively enhance the usability and inclusivity of web applications.

Full Context
A 2-minute read.
GitHub Copilot's `review` command marks a significant advancement in developer tooling, offering automated code analysis that can act as a vigilant AI pair programmer. This command, deeply integrated into the Copilot CLI, is designed to scrutinize any code changes a developer has made, offering a rapid, intelligent review before those changes are committed. The core benefit is an immediate, AI-powered quality check that can catch potential issues early, thereby streamlining the development workflow. It intelligently identifies what needs reviewing by first running a `git status` to find uncommitted changes; if the working directory is clean, it compares the current branch with the main branch.
Operating the `review` command in 'autopilot mode' with all permissions granted is highlighted as a practical approach for efficiency. This configuration enables Copilot's 'code review sub-agent' to execute a series of necessary Git commands without pausing to ask for explicit permission at each step. This significantly reduces friction, especially during complex reviews that might involve multiple Git operations, thereby accelerating the feedback loop and allowing developers to iterate faster. The speaker notes that this setup is crucial to prevent the process from becoming bogged down by constant permission prompts.
A compelling demonstration of the `review` command's capabilities involved its detection of a missing focus style on a Call-to-Action (CTA) button within a newly added 'about page.' Strikingly, Copilot didn't just suggest a fix; it automatically edited the code to resolve the issue, stating 'Fixed. The focus visible rule gives keyboard users a clear gold outline when they tap to get started.' This autonomous action showcases a powerful aspect of AI in development: not just identifying problems, but actively solving them. However, this level of automation also sparked a critical reflection from the speaker. While acknowledging the utility, they expressed a clear preference for the AI to inform them of the error and then await explicit instruction before applying a fix, rather than proceeding unilaterally. This incident underscores a crucial ongoing debate in AI integration: balancing efficiency gains with developer control and oversight. The speaker indicates this was the first instance they observed Copilot making an unprompted correction, suggesting a potential shift in the tool's behavior or a specific outcome of the 'autopilot' configuration. Despite this, the `review` command is recommended as an invaluable 'extra pair of eyes' for more complex tasks where thorough validation before committing is paramount. Ultimately, the `review` command represents a powerful step towards more intelligent and automated software development, albeit one that requires careful consideration of human-AI collaboration dynamics.
