"Disregard That" Attacks

https://calpaterson.com/images/screenshots/disregard-that.png
Large Language Models (LLMs) are vulnerable to "Disregard that!" attacks, where untrusted input can be injected into the model's context window, leading to security issues. The problem cannot be solved by adding more agents or using AI guardrails, and the only effective mitigation is to not allow untrusted input into the context window.

Thoughts on slowing the fuck down

https://mariozechner.at/posts/2026-03-25-thoughts-on-slowing-the-fuck-down/media/header.png
The author warns that relying on coding agents can lead to brittle, complex, and unmaintainable codebases due to their inability to learn from errors and lack of global understanding. To avoid this, humans should slow down, use agents for non-critical tasks, and maintain agency over their codebases to ensure quality and maintainability.
