codex-app-mirror-installer

Skill by ara.so — Codex Skills collection.

This skill provides expertise in using the codex-app-mirror project to download and verify official Codex desktop app installers. The project mirrors Windows MSIX (from Microsoft Store) and macOS DMG installers to GitHub Releases every 15 minutes, with SHA256 checksums and version manifests.

What It Does

codex-app-mirror automatically polls Microsoft Store and OpenAI's official CDN for Codex desktop app updates, then publishes verified installers as GitHub Release assets. It does NOT modify, repackage, or build Codex — it only mirrors official packages with checksums.

Mirrored Assets:

• Windows x64 MSIX (Microsoft Store ProductId 9PLM9XGG6VKS)
• macOS Apple Silicon DMG (arm64)
• macOS Intel DMG (x64)
• SHA256SUMS.txt (checksums for all assets)
• release-manifest.json (upstream fingerprints)
