About Libretto PR agents

Automatically investigate failing Playwright scripts against the live page and open a GitHub pull request with a proposed fix. The PR agent starts only after a failure, when it can investigate what changed and propose a fix. Run locally, in your own infrastructure, or with a hosted browser provider. The PR agent focuses on diagnosing the failure and proposing a code fix for future runs. Your existing catch, retry, fallback, and error handling remain responsible for the current run, while the agent opens a pull request when it finds a fix.
