# Old runtimes and when support ends

Prompt · Infrastructure and environment · I07

The safe version of the viral 'delete old Chromium builds' prompt.

## Prompt

```text
Inventory actual versions and dependencies of Playwright, Puppeteer, system Chrome, Chromium caches and Electron apps. Verify current vendor-supported and security-fix thresholds rather than trusting hard-coded version numbers. Distinguish safe disposable caches from app-owned runtimes and report the rollback path before any cleanup.
```

**What it returns:** Each runtime with version, owner app, support status from the vendor, size, and a rollback path.

**Skip it when:** When browser tests are stable and disk space is fine.

**Tools:** A terminal on your computer; vendor release pages.

**Watch for:** Do not delete shared runtimes or force a system Chrome until every dependent app is known.

**Changes:** Changes nothing

**Sessions:** One session
