Ghost Invasion
ChatGPT pluginFind bugs you can reproduce, then check your fix against the same test. Ghost Invasion runs repeatable browser test journeys against a disposable local app using synthetic data. It records reports, browser traces and state-change evidence so you can inspect what happened and replay the failure. The bundled test engine includes a demonstration that detects a known fault, reproduces it and checks a fixed version. Use only an explicitly approved, trusted local test app with fake data, never production or real accounts. Requires a local coding assistant, Node.js 22+, npm and Playwright Chromium on macOS or Linux. The test engine itself needs no paid model API calls.
