Mailbox CLI Skill

Drives the @leeguoo/mailbox-cli Node CLI to read and manage email across multiple IMAP accounts. Returns a stable JSON contract — every response includes success: boolean and, on failure, error: string + error_code: string (machine-readable).

Compatibility — check the CLI version first

If mailbox is not on PATH (command not found / mailbox: not found), install it non-interactively from GitHub Releases (no npm, no auth) before doing anything else:

curl -fsSL https://raw.githubusercontent.com/leeguooooo/Mailbox/main/install.sh | sh
# installs the prebuilt binary to ~/.local/bin — make sure that's on PATH, then re-probe
export PATH="$HOME/.local/bin:$PATH"; mailbox --version
