LLMs

Retrieval-augmented generation makes language models far more useful by grounding them in real data, But it also raises a hard question: who is allowed to see what? This post shows how authorization can be enforced before retrieval, ensuring that RAG systems remain powerful without becoming dangerous.

Whenever a new pull request is submitted to our agent’s GitHub repository, we run a bunch of CI/CD operations on it. We run an opinionated linter, we run typechecking, and we run a bunch of unittests. All of these work well, but none of them test entire workflows end-to-end. For that end-to-end testing, we introduced an eval pipeline. This is part of the Building an internal agent series. Why evals matter The harnesses that run agents have a lot of interesting nuance, but they’re generally pretty simple: some virtual file management, some tool invocation, and some context window management. However, it’s very easy to create prompts that don’t work well, despite the correctness of all the underlying pieces. Evals are one tool to solve that, exercising your prompts and tools together and grading the results.

Agents are extremely impressive, but they also introduce a lot of non-determinism, and non-determinism means sometimes weird things happen. To combat that, we’ve needed to instrument our workflows to make it possible to debug why things are going wrong. This is part of the Building an internal agent series. Why logging matters Whenever an agent does something sub-optimal, folks flag it as a bug. Often, the “bug” is ambiguity in the prompt that led to sub-optimal tool usage. That makes me feel better, but it doesn’t make the folks relying on these tools feel any better: they just expect the tools to work.

Retrieval-augmented generation breaks at scale because organizations treat it like an LLM feature rather than a platform discipline. Enterprises that succeed with RAG rely on a layered architecture.

Yes, this is the umpteenth article about AI and coding that you’ve seen this year. Welcome to 2025. Some people really find LLMs distasteful, and if that’s you, then I would recommend t…

For IT and HR teams, SLMs can reduce the burden of repetitive tasks by automating ticket handling, routing, and approvals, while providing substantial cost savings versus LLMs.

If your access control lives in a prompt, it isn’t access control. Authorization decisions must be deterministic and enforced before an LLM ever sees data. Treating AI as a policy engine is a category error with real consequences.
