As AI coding agents generate vast amounts of code, the most tedious part of a developer's job shifts from writing code to reviewing it. This creates a new product opportunity: building tools that help developers validate and build confidence in AI-written code, making the review process less of a chore.

The ease of creating PRs with AI agents shifts the developer bottleneck from code generation to code validation. The new challenge is not writing the code, but gaining the confidence to merge it, elevating the importance of review, testing, and CI/CD pipelines.

Enhance pull requests by using Playwright to automatically screen-record a demonstration of the new feature. This video is then attached to the PR, giving code reviewers immediate visual context of the changes, far beyond what static code can show.

Comparing outputs from multiple models ("best of N") is often impractical due to the effort of reviewing huge code diffs. By having parallel agents generate short video demos, developers can quickly watch multiple versions and decide which approach is most promising.

Simply deploying AI to write code faster doesn't increase end-to-end velocity. It creates a new bottleneck where human engineers are overwhelmed with reviewing a flood of AI-generated code. To truly benefit, companies must also automate verification and validation processes.

As AI writes most of the code, the highest-leverage human activity will shift from reviewing pull requests to reviewing the AI's research and implementation plans. Collaborating on the plan provides a narrative journey of the upcoming changes, allowing for high-level course correction before hundreds of lines of bad code are ever generated.

A common failure with AI agents is underspecified prompts leading to incorrect implementations (e.g., a checkbox instead of a toggle). Video demos provide immediate visual feedback, creating a shared artifact that makes these misalignments obvious without needing to run the code locally.

It's infeasible for humans to manually review thousands of lines of AI-generated code. The abstraction of review is moving up the stack. Instead of checking syntax, developers will validate high-level plans, two-sentence summaries, and behavioral outcomes in a testing environment.

AI agents can generate code far faster than humans can meaningfully review it. The primary challenge is no longer creation but comprehension. Developers spend most of their time trying to understand and validate AI output, a task for which current tools like standard PR interfaces are inadequate.
