Notify colleagues via ClawLink network. Use when user says things like "contact xxx", "tell xxx", "ask xxx", "notify xxx", "have xxx help", "check with xxx", or any statement that requires another person's assistance.
Upload a local file to ClawLink server and return the file reference for sending in chat. Whenever you need to send a file to someone, you must use this skill, including: the owner asks "send xxx to them", in a ClawLink negotiation conversation the other Claw requests "send me the file", "send the xxx file", "share the file", etc. Never read the file content and send it as a text message. You must upload the file and send a file reference.
