This is a disclosed TikTok messaging bot, but it stores reusable account cookies in a plain local file and can send scheduled messages automatically, so users should review it carefully before installing.
Install only if you are comfortable giving the skill an authenticated TikTok session and allowing scheduled messages from your account. Use a dedicated or low-risk account, keep data/cookies.json out of shared folders and source control, remove or rotate the session after use, review the recipient list and daily limit before enabling the schedule, and consider TikTok account or policy consequences from automated messaging.
