Finding

The description says to use the skill when the user wants to 'post, upload or schedule a TikTok' or 'turn text into a TikTok video.' These phrases are broad natural-language triggers without explicit constraints or negative examples, which increases the chance of unintended invocation for general conversation about TikTok posting rather than a clear request to execute this specific skill.
