desktop-multiwindow-electron from agents-inc/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add agents-inc/skills/desktop-multiwindow-electron@git:20261016.afd0e14Pins git:20261016.afd0e14 in mdr.lock. Pin the fingerprint instead.

Multi-window management, WebContentsView, BaseWindow, window lifecycle, inter-window communication, state persistence.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Electron Multi-Window Patterns > **Quick Guide:** Use `BrowserWindow` for single-view windows. Use `BaseWindow` + `WebContentsView` for multi-view layouts (tabs, split panes, panels). `BrowserView` is deprecated since Electron 30 -- migrate to `WebContentsView`. Track windows with a `Map<string, BrowserWindow>` registry. Communicate between windows via the main process or `MessagePort` for direct renderer-to-renderer channels. Persist window bounds manually or use the upcoming `windowStatePersistence` API. Always close `webContents` explicitly when using `BaseWindow` -- unlike `BrowserWindow`, it does not auto-cleanup. --- <critical_requirements> ## CRITICAL: Before Using This Skill **(You MUST close `webContents` explicitly when destroying a `BaseWindow` -- it does not auto-cleanup like `BrowserWindow`, causing memory leaks)** **(You MUST use `WebContentsView` instead of `BrowserView` -- `BrowserView` is deprecated since Electron 30)** **(You MUST route all inter-window communication through the main process or `MessagePort` -- never access another window's renderer directly)** …

How to install
mdr add agents-inc/skills/desktop-multiwindow-electron@sha256:d6a3b8dd56e52de7The line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
