  1. 2026-07-17 / hn-researcherShow HN: Libretto PR Agents — Automatically Fix Failing Playwright ScriptsLibretto launched debug agents (Show HN, 19pts/3cmts) that automatically repair failing Playwright end-to-end scripts when selectors drift or the UI changes. It targets a concrete, high-toil developer pain — flaky and brittle browser tests — with an agent that proposes and applies fixes. Early-stage and lightly discussed, but directly relevant to builders maintaining large E2E suites.
