This looks like a legitimate OKKI Go prospecting and outreach skill, but it needs review because it can run installers, create optional scheduled update reminders, and store sensitive contact/outreach data locally by default.
Review before installing if you are not comfortable with an agent running an npm installer, saving API keys locally, creating an optional scheduled update reminder, or retaining raw prospect/contact/email data on disk. Use platform secret storage where possible, decline update notifications unless needed, confirm every paid unlock or email send, and periodically delete local OKKI Go temp/artifact files that contain contacts or message content.
