Keysmith Switch for macOS and Windows
A native desktop app for macOS and Windows. The adapters for all four agents come inside it, so it works as soon as it's installed; there's nothing else to set up.
No account, no sign-in. Install it and open it. Your library lives in ~/.keysmith-switch/ on your computer and stays there even if you uninstall the app.

What's inside
A prompt library
Kept per agent, with tags, search and edit history. On first launch it finds Keysmith prompts already on your computer and lets you choose which to import.
Four built-in adapters
The adapters for Claude Code, Codex, Grok Build and ZCode install and update with the app; there's nothing to download separately.
In-app updates
A red dot in Settings means a new version is out. One click updates, and only when you say so. Your library stays as it is.
macOS / First launch
The first time, macOS may say the app can't be opened or that its developer can't be verified. Open System Settings → Privacy & Security, find Keysmith Switch near the bottom, click Open Anyway and confirm. After that it opens normally. On macOS 14 and earlier you can also right-click it in Applications and choose Open.
Windows / Install warning
Windows may show “Windows protected your PC”. Click More info, then Run anyway. It installs into your own user folder and doesn't need administrator rights.
Antivirus / False alarms
A few antivirus programs may flag Keysmith Switch by mistake. If you downloaded it from this page, it's a false alarm: restore the file from quarantine and add Keysmith Switch to the trusted list (allowlist). Not sure? Ask us on GitHub.
Have your agent install it
Read the README and release boundaries at https://github.com/Jia-Ethan/keysmith-switch first, then install the current stable version from the public Releases. Before acting, check the system architecture, any existing version and the data folder, and list the exact download, install and backup paths; wait for confirmation before replacing an existing app or writing managed configuration. After installing, do a minimal check of the installer's SHA-256, that the app starts, that existing prompt data is intact, and “Check for updates”. Do not build from source unless asked.Installers are only offered on this page and the official GitHub releases page. Don't open an installer you got anywhere else.
