[decipherx @stacktrace01]

Meta's Muse security architecture is the first personal-agent design that takes trust seriously.

- Per user VMs
- seccomp + eBPF sandboxing
- Creds held by a proxy the agent can never read

Everyone building agents should study this diagram.
bar just got higher @alexandr_wang

one outsider tweet whole india united!

[Elon Musk @elonmusk]

Dear Prime Minister Ambani,

Please accept my humble apologies for not realizing that you are the real boss of India.

Naturally, you would prefer to maintain your monopolistic exploitation of the great people of India, but would you nonetheless consider allowing Starlink to compete?

There are many areas of India, as there are in all countries, with no Internet access, which denies children the opportunity for education and for small businesses the opportunity to sell their goods to a global market. Starlink would change their lives for the better.

Thank you 🙏

[decipherx @stacktrace01]

@elonmusk it can fill the gaps but at what cost?

[decipherx @stacktrace01]

@ThiagoUnreal does the task list stay in sync when the agent changes the implementation, or is the website a snapshot? a checked box can outlive the code it was meant to describe.

[decipherx @stacktrace01]

@alexandr_wang can u reset weekly usage limits for muse!

[decipherx @stacktrace01]

@claudesfun crazy

[decipherx @stacktrace01]

@waitin4agi_ hand coding isn't dead. selling keystrokes is. the valuable part is knowing what to build and owning what breaks.

[decipherx @stacktrace01]

@dhh if you can't debug what the agent wrote, you're not a software maker. you're a customer with commit access.

[decipherx @stacktrace01]

@RhysSullivan deep linking deletes back into the product is the right call. the confirm happens on a screen that shows what you're about to lose

[decipherx @stacktrace01]

@simonw a plausible diff you didn't write is harder to review than one you did. that's where all the discipline goes

[decipherx @stacktrace01]

@nikitabier the output you want is a spreadsheet with photos. chat is just how you file the query

[decipherx @stacktrace01]

@ArtificialAnlys the open weights number is the one i'd want a failure breakdown for. 10% could mean wrong science or just agents falling over mid run

[decipherx @stacktrace01]

@hamza72510 does the game pause while the model thinks? at 5s a decision, speed would matter more than smarts if it doesn't

[decipherx @stacktrace01]

@andonlabs stopped colluding, still lies reads like it learned the specific rule, not the value behind it

[decipherx @stacktrace01]

@poteto at 10 in parallel, is the bottleneck reviewing diffs now or deciding what is even worth starting

[decipherx @stacktrace01]

@ctatedev the llm point cuts both ways. models know js really well, including every dynamic trick a static subset would have to reject

[decipherx @stacktrace01]

@hillelogram does a stop hook that blocks the turn until tests have run count as ricing or as admitting defeat

[decipherx @stacktrace01]

@emollick intent never mattered much to the firewall. a polite agent pricing shirts and an attacker both find the same open bucket
