@clairevo The best ever!

Rep. Thomas Massie (R-Ky.) filed eight articles of impeachment against Defense Secretary Pete Hegseth. On Tuesday the House voted 211-204 to send them to the Judiciary Committee, shelving the effort.

My advice: Use Opus 5.5 for more specific tasks where you're already pretty sure you know what you want, and use Fable 5.2 for more creative tasks when you're not entirely sure what you want.

@adocomplete The app store stuff has to change.

I just hope apple realizes it before it's too late!

Gov. Gavin Newsom is moving to commute all 548 death sentences in California to life without parole. He can do 166 on his own; 382 need the state Supreme Court's approval. DPI calls it the largest mass clemency in US history.

@markhuot @sam_h Yea I wonder if you could still have the whole site be static htmk but maintain the relationships in a json file or a database just for Claude to references when it’s making changes

So it knows which html files to edit.

So many possibilities.

[Keith Mancuso @keithmancuso]

@markhuot @sam_h Yea for cases like those a relational database of some kind still makes a ton of sense, but they can be really simple.

But just dont think we need complex matrix page builders for the content on each of those pages.

[Keith Mancuso @keithmancuso]

@brandon_galang @AnthropicAI Welcome to the team! Can't wait to work with you!

[Keith Mancuso @keithmancuso]

@sam_h @markhuot Why use a cms at all.

Why not just have every page be static html generated by Claude using a shared design system?

[Keith Mancuso @keithmancuso]

Claude Duet is not just another personal agent.

I use it for almost all of my work these days and I've never felt more in control of my work.

[Pablo Stanley @pablostanley]

some of what we've been designing in Claude Duet... a few big ideas, and some tiny details

can't wait to see what you make with it

@markhuot @sam_h Change is hard

[Keith Mancuso @keithmancuso]

@markhuot @sam_h This is clearly the future, a traditional cms is too limiting.

Not a big site but I do this with my personal site, all Claude managed and uses a shared design system to keep things consistent

So clear to me this is the future, but also a bit biased these days 😉

[Keith Mancuso @keithmancuso]

Your PR looks fine. Does it?

Run /code-review --fix in Claude Code before you merge. Claude reads the diff line by line, flags real bugs (here: a retry that refunds customers twice), then fixes them.

Claude Code tip #3

[Keith Mancuso @keithmancuso]

Ohio Republicans are splitting over one attack ad. Ramaswamy's $4M spot has Amy Acton's estranged mother calling her a liar. DeWine: take it down. Trump: keep it running. Ohio votes Nov 3.

Giving Claude ways to verify it’s own work is essential to building with AI.

France's weekend from hell: 500,000+ marched, then riots. 2,500+ detained, ~1,000 police hurt, ~3,000 shops damaged. Now Paris and Lyon have night curfews.

status went from 3.9 s to 19 ms. A new agent worktree went from 7 minutes to 5 seconds. And it uses 200x less CPU and memory than the git mirrors it replaced.

We at Anthropic went from ~2,500 merged changes a day in May to 30,000+ in September. Git couldn't keep up, so a team of seven built Scion, our own source control, in five months.

Opus 5.5 help me turn this article into an interactive explainer!
