mc-serious··on Show HN: Forge – Guardrails take an 8B model from 53% to 99% on agentic tasks
Really cool direction. For folks thinking about the “agent safety” stack more broadly, this feels complementary to things like Kontext’s kontext-cli (github.com/kontext-dev/kontext-cli) and OneCLI (github.com/onecli/onecli)
mc-serious··on Access to frontier AI will soon be limited by economic and security constraints
Open-Source will handle access to models, someone will find a way. Security by obfuscation has never worked.
mc-serious··on Show HN: Upskill – skill to find skills for your AI agents
hm i see so a bit like pagerank for md files - would be curious about the equivalent to backlinks, what do you think that is for skills? Skills that embed other skills?
mc-serious··on Show HN: Tilde.run – Agent sandbox with a transactional, versioned filesystem
Yeah tbh I think this might be close to impossible to do as it probably 1) requires alignment that every stateful system needs a rollback capablity 2) it needs to be standardized which will probably take a minimum of 2 years after consensus (and that's probably conservative).

I'd love to learn more on how egress can be handled securely in sandboxes, and in general also ingress as this has some security impact - as soon as you allow reading from an external system you open up a new threat vector. Curious to understand whether you have any strategy for network access?

How's this different from the built in skill finder? Anything specific?
mc-serious··on Show HN: Tilde.run – Agent Sandbox with a Transactional, Versioned Filesystem
Nice, I think that's pretty neat. Do you have an idea where to take this further? I.e. for the filesystem it's great but what if you need to touch external systems that keep their own state?
