design teams are drowning in review. more agents shipping more UI, and either sh*t gets shipped or design slows everyone down.

so we built a design review agent that lives in GitHub PRs. encode a ruling once, it runs on every PR forever.

Genuinely useful migration guide. Can’t wait to see Opus 4.7 in action!

Introducing Claude Opus 4.7, our most capable Opus model yet.

It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back.

You can hand off your hardest work with less supervision.

[Steve Cooper @BlueTeamSteve]

@felixm_pw This is really powerful. Often hard to pick out specific low level techniques and test in isolation

@sebgoddijn @buchan_sm Thanks!

@sebgoddijn Looking forward to it!

[Steve Cooper @BlueTeamSteve]

Even very complex work still only requires deep reasoning every few steps. But you never know *when* that reasoning step is needed.

So let the executor agent decide!

[Claude @claudeai]

We're bringing the advisor strategy to the Claude Platform.

Pair Opus as an advisor with Sonnet or Haiku as an executor, and get near Opus-level intelligence in your agents at a fraction of the cost.

@hwchase17 @daytonaio @modal @RunloopDev Looking forward to seeing this evolve! Deployment is a hard problem so glad you folks are tackling it.

@aiDotEngineer Europe has been the highest signal conference I’ve seen to in a long time.

And I’m also old like @badlogicgames so I’ve been to plenty in my time!

@garrytan @mercor_ai Yep looks like some interesting RL post-training datasets.

[Steve Cooper @BlueTeamSteve]

@AlvieriD @mercor_ai That’s a nasty breach. Lots of personal data!

Some fantastic tips. 👀

/loop and PR feedback cleanup is a great idea.

I wanted to share a bunch of my favorite hidden and under-utilized features in Claude Code. I'll focus on the ones I use the most.

Here goes.
