in OpenCode v1.1.18 we implemented the detailed planning flow you find in cursor or claude code
but not 100% sure about it yet so we put it behind a OPENCODE_EXPERIMENTAL_PLAN_MODE=1 feature flag
quick video on how it works but if you have feedback please put it on this thread

#Iran has now been largely offline for over 18 hours. It appears that access to @1111Resolver was briefly restored around 10:00 UTC. Internal data suggests some nominal traffic recovery starting around 09:00 UTC, but volumes remain extremely low.

I was locked inside a plane on 9 hours flight, so I finally watched TRON: Ares. What a waste of time.

Looks like the MTV of my generation goes (officially) offline today. I have fond memories of discovering great music on MTV and endless hours watching Beavis and Butt-head. MTV was actually one of the reasons why I put a giant satellite dish on the roof before cable was a thing in my country.

“Once it’s on the Internet it stays there forever” is no longer true. It’s increasingly hard, if not impossible, to find old information about niche topics using traditional search engines. We should al support open preservation projects around the world, they’re doing important public service.
