This is a mostly documented executive-assistant template, but it grants and encourages very broad account, browser, local-command, and persistence powers that users should review carefully before installing.
Install only in a sandbox or dedicated assistant workspace first. Use a dedicated Google account where possible, grant only the specific OAuth scopes you need, protect credential and token files, disable or ignore browser-login automation unless you need it, and require explicit confirmation before sending email, sharing files, modifying calendars, pushing git changes, spending money, or submitting forms.
