Libretto PR Agents - Automatically fix failing Playwright scripts

Libretto PR Agents revolutionizes browser automation by automatically diagnosing and fixing failing Playwright scripts. When a test fails, the agent investigates the live page, identifies the root cause, and instantly opens a GitHub pull request with a proposed code fix. This solution integrates seamlessly with existing workflows without requiring a new runtime, allowing developers to keep their current browser providers and deployment structures. By automating the repair loop, Libretto ensures that your automation scripts remain robust and up-to-date with minimal manual intervention.

"Keep your scripts. Add the repair loop."
