Core Breakthrough: From "Chatbox" to "Toolbox"
Previously, users often had to repeatedly input background information when using AI, but the "Skills Library" has completely changed the interaction logic:
Custom Skills: Users can save common AI tasks (such as: analyzing components, comparing specifications, extracting summaries). When calling them next time, just type a slash "/" followed by the skill name in the sidebar, or click the plus sign.
Run Across Tabs: Selected skills can not only run on the current page, but also apply to other selected tabs, enabling batch processing.

Efficiency Office Work: Facing long documents or complex agreements, directly call the "Scan and Extract" skill to instantly obtain key information.
