![[BUG] `mcp__claude-in-chrome__*` tools absent entirely on Windows (MSIX-hosted sessions) — present...](https://pbs.twimg.com/card_img/2121420530159087616/-H3X7gqM?format=jpg&name=800x419)
6/ Filed fresh today with the full A/B and elimination list:

~15 more Claude-in-Chrome issues opened this week alone. The bugs aren't going away — the reports are.

5/ anthropics/claude-code#58009 documented the MSIX/AppContainer native-messaging failure in detail. A bot closed it in 3 days: "doesn't appear to be about Claude Code." Locked 7 days later. The technical content was never assessed.

4/ Two were accepted — labelled bug, has repro, platform:windows — then auto-closed as stale. Reproducible, acknowledged, closed by a clock.

3/ Reports go back to 9 Feb 2026:
anthropics/claude-code#24539 · anthropics/claude-code#25162 · anthropics/claude-code#52766 · anthropics/claude-code#56949 · anthropics/claude-code#58009 · anthropics/claude-code#58201
Every one closed. None fixed.

2/ Not a misconfiguration. Checked against a known-good Mac: native-host registry key, manifest chain, wrapper parity, extension ID, extension state, CLI version — all identical or better on the failing machine. It registers 7 browsers to the Mac's 2.

1/ Claude in Chrome doesn't work on Windows. The browser tools don't error — they're absent from the session entirely. Same Claude Code version (2.1.260) on macOS works fine. @AnthropicAI

The race is on
Patching these vulnerabilities will make us safer. But the software industry will need to adapt to the volume of vulnerabilities that models like Claude Mythos Preview will be able to find.
We discuss this in our initial update on Project Glasswing: anthropic.com/research/glass…

Anthropic CEO: "AI will write 100% of code within a year"
developers spend 4 years in university learning to code
Claude learned it from every book ever written
if the hardest skill is already handled - the gap is no longer about what you know
it's about how well you've configured the tool that knows everything
most people haven't done that yet
the article below is where you start
Sean Sullivan retweeted
you'll need to explicitly prompt Claude Code to use it, but the Monitor Tool is super powerful
e.g. "start my dev server and use the MonitorTool to observe for errors"

Introducing Project Glasswing: an urgent initiative to help secure the world’s most critical software.
It’s powered by our newest frontier model, Claude Mythos Preview, which can find software vulnerabilities better than all but the most skilled humans.

There are a thousand frameworks released a day to help you build better apps with AI. It's impossible to keep up.
But underneath, they're all the same.
They all use the same 7 phases to turn ideas into working code:

I told a young guy recently that his number of £250k was greedy.
He asked why, and I said that number only satisfies him.
If he had kids or sick parents, his number would be bigger.
The more people you think about, the bigger the number.
Wanting more isn’t greedy - wanting less is.
Flip your script.
Powerful people want you to believe it's greedy to want more.
Love it
💥 Rainbow Parade Interrupted by ManUp Flash Haka 💥
Our Radical Young People have had enough!
Our ManUp Men have had enough!
Destiny Church has had enough!
The debauchery in the Rainbow Parade has gone on for too long!
Auckland has long been overrun with this Woke, Rainbow Agenda and here's some of our Gen Z rising up to say...they have had enough!
And no surprise, the Boys in Blue were there again...protecting their beloved rainbows.
The NZ Police are no longer the thin blue line protecting law and order — they prioritise protecting rainbows. What a joke they have become, waving their NZ Police Rainbow flags and parading their Rainbow Cars.
I'm putting all these government organisations, politicians and councils on notice. The time for your Woke Agendas is over. Get out now before you are thrown out.
It's time for The People's Movement to arise and put an end to the stupid.
Let's Make NZ Great Again!
This is only the beginning...
Follow Me to see what we have planned next...
