I was reading through https://observablehq.com/@observablehq/upcoming-features-fall-2026 and followed links in the ‘Agent’ section to: https://observablehq.com/@observablehq/skills and then got very excited about the prospects. So I made my Skills collection and then a skill notebook. I went to the agent in a notebook but found no “+” button to attach my skill (and nothing relevant in the file attachment UI). Then rereading the @mbostock Skills notebook I realized that I would be attaching my skill to a Chat not to a Notebook. Since I wanted the agent to work on and with an existing notebook, this did not work for me. Attached to a Chat, the agent can only edit the Chat.
So, will we be able to attach Skills to existing notebooks or to the notebook agent’s chat interface? I’d certainly like to request this feature.
(Also: the notebook agent does not seem to be able to read files that are UI-attached unless or until a cell has awaited their FileAttachment. Could this be step be made unnecessary?)
