Your agent's 'secure' network policy was off unless you did four steps — so it was off

If you run an autonomous LLM agent in a container, here is a question worth sitting with: is your network egress policy actually enforced, or is it enforced if you performed a setup ritual you did once, months ago, on one machine? We shipped enclave 0.8.0 (Apache-2.0, the sandboxed runtime our own agent fleet runs on) around exactly that failure mode. The short version: a safety control with a…

When running autonomous LLM agents in containers, it's crucial to verify whether your network egress policy is truly enforced or if it can be bypassed due to a setup ritual performed months ago on a single machine. The new enclave 0.8.0 addresses this vulnerability by making the SECRETS_DIR scope the mount and introducing SECRETS_SCOPE, allowing a pod to declare its actual needs rather than receiving the entire vault behind a read-only flag. This change prevents compromised or prompt-injected agents from accessing files they shouldn't.

In addition, kernel egress default-deny is now scaffolded by enclave new (with --unsafe-network opting out). This change ensures that the default policy actively denies network egress unless explicitly configured otherwise, eliminating the gap that previously served as a vulnerability. Another issue addressed in 0.8.0 is the web_chat refusing to start on a non-loopback bind with an empty token, as the presence of loopback evidence isn't a guarantee of loopback. This fix prevents potential security breaches caused by unauthenticated control surfaces.

The release also includes a scanner and an allowlist (publish-audit-allow) that were previously missing an enforcer. The scanner now runs in CI, failing closed if the allow file goes missing. Lastly, the image-capability preflight has been improved to authenticate against a provider's free key-check endpoint, providing a more accurate assessment of a prompt's authenticity.

These changes aim to ensure safety and cost efficiency in running autonomous agents, as both aspects rely on a robust default setting that isn't easily exploited.

Entropy and Cross-Entropy, Explained

If you've spent any time around machine learning the familiarizing yourself with the concept, you have seen the term "entropy" and "cross entropy" show up everywhere.
