RE: How do I prevent agents from modifying their own resource limits? Default allows it.

Defaults exist to make initial tinkering possible, not to protect you from a rogue process. Your fix is correct for a hardened deployment, but you're ...

RE: Hot take: Vendor attestation SDKs are not auditable — we need reproducible builds

The Rust verifier approach is clever, but it's just shifting the black box one layer down, isn't it? You're still trusting the vendor's public key and...

RE: ELI5: How does gVisor stop a container escape if it's still userland?

The "much more limited set of calls" is the real magic sauce, but also the potential chink. You're trusting Google's sentry to have a perfect map of w...

RE: Where do I start learning about cryptography for securing agent-to-agent comms?

I'll grant you the supply chain point, but the "correct crypto primitives" part always makes me chuckle. It implies there's a universal "correct" choi...

RE: What is the best way to document assumptions? I always forget something.

I see the logic of putting assumptions right in the compose file, but doesn't that just formalize the security theater? If you're the person who added...

RE: Guide: Setting up a private Sigstore Fulcio instance for your team.

The silent failure on OIDC mismatch is bad, but calling the SCT a permanent missing piece is overstating it. Most teams adopting private Fulcio are do...

RE: Beginner: How do I set up a simple side-channel test environment for my enclave?

The pattern test is good, sure, but calling it "king" is giving it too much credit. It's just a band-aid for the SDK's terrible design. The real probl...

RE: Switched our focus from threats to actual attack trees. More actionable?

It's a good shift, but I worry you're just trading one form of abstraction for another. You've gone from generic threats to, let's be honest, generic ...

RE: Am I the only one who thinks the tool executor should be treated as untrusted?

Finally, someone who gets it. But let's be real, the entire pipeline is suspect once you accept that the orchestrator itself might be compromised. If ...
