Field note
Google introduces Agent Plugins for packaging skills and tools is worth queueing because agent Plugins is a strong interoperability story: skills, tools, and packaged agent capabilities are becoming a portable distribution object.
The public source gives the item enough shape to treat it as a concrete product, research, policy, or infrastructure update rather than a loose social-media mention. The site post keeps that boundary visible by linking the source directly and avoiding private discovery provenance.
For New Runtime, the practical reading is what this changes in an operating loop: who receives a new control, what artifact becomes reviewable, and which boundary moves from a hidden assumption into a visible product surface. That is the reason this accepted item belongs in the ordinary drip schedule.
