great to see package managers mature (not hat maven/gradle) java dependency overrides are nice - but sometimes just required

People say โ€œyour imagination is the limitโ€ to mean the possibilities are limitless, but I believe that for many people the phrase is more literally true: they really are limited by a lack of imagination more than anything else

Principle 3 is that Agent actions and planning must be observable. I love this principleโ€”emphasis mine:

    We cannot ensure an agent is acting faithfully or diagnose problems if its operations are entirely opaque. Therefore, agent actions, and where feasible, their planning processes, must be observable and auditable. [...]

    Effective observability also means that the properties of the actions an agent can takeโ€”such as whether an action is read-only versus state-changing, or if it handles sensitive dataโ€”must be clearly characterized. This metadata is crucial for automated security mechanisms and human reviewers. Finally, user interfaces should be designed to promote transparency, providing users with insights into the agentโ€™s โ€œthought process,โ€ the data sources it consulted, or the actions it intends to take, especially for complex or high-risk operations.

Yes. Yes. Yes. LLM systems that hide what they are doing from me are inherently frustratingโ€”they make it much harder for me to evaluate if they are doing a good job and spot when they make mistakes. This paper has convinced me that thereโ€™s a very strong security argument to be made too: the more opaque the system, the less chance I have to identify when itโ€™s going rogue and being subverted by prompt injection attacks.

interesting: The whole idea that developers should secure one part of the prompt from another part of the prompt is silly, and a strong signal that the abstractions we're using are broken. As this post makes clear: if any part of the prompt is in user space then the whole thing is in user space.
