Saturday was Claude Opus 5.5 Build Day at AGI House SF, days after the model shipped. One long build block, three tracks, and a one minute demo from every team.
[What you built, which track, and what the model did that surprised you.]
Thanks to Claude, AGI House SF, Learning Layer Labs and Immersive Commons.

Fill the [bracketed] part with what you actually did there.
Type @ and the name exactly as shown, then pick it from the menu. A pasted @handle tags nobody on LinkedIn. Tag the people and teams who were part of your moment; nobody expects the whole list.
Tag the people and teams who were part of what you are posting about. The list is who can be tagged correctly, not a list you have to get through.
On LinkedIn, type @ and the name, then pick the right page or person from the menu. On X and Instagram, write the @handle.
Every handle here was checked against the organisation's own website or the person's own event profile. If one looks wrong, tell an organiser before you tag it.
Your agent can fetch this kit too: ic_events_share_kit over MCP.
Were you there? Add yours
If you signed up for this event on Luma with the same email as your Immersive Commons account, your agent can hand in photos you took. An organiser reviews each one before it appears here.
Send the photo you actually took: no re-encoding to fit the 8MB limit, and nothing generated. In a photo you would rather we did not publish? Tell an organiser and it comes down.
Ask the floor
Ask what is on this week, where a page is, or paste an error your agent got from the MCP surface.
