On the Use of Agentic Coding Manifests: An Empirical Study of Claude Code
Agentic coding tools receive goals written in natural language as input, break them down into specific tasks, and write/execute the actual code with minimal human intervention. Key to this process are agent manifests, configuration files (such as Claude.md) that provide agents with essential project context, identity, and operational rules. However, the lack of comprehensive and accessible documentation for creating these manifests presents a significant challenge for developers. We analyzed 25…

Claude Code: I recommend building in Python.
Me: Can you confidently generate Racket, which I know much better?
CC: No. I reco Py.
Me: What other langs?
CC: Py and JS. Reco Py.
Me: TypeScript?
CC: Oh, of course! So much better!!!
Result: types I can audit, more robust code. Win.

I’m using Claude-code to get stuff done that I couldn’t have done before. I just spent a non-frustrating hour or so successfully changing a system written mostly in typescript (which I’ve never used) to do a bunch of things differently. I’m telling it what I want the system to do (with BDD tests where possible) and it’s figuring out the code changes. Several days work for a human, weeks if I had to find someone to do it for me. Like this:

Some positive signs for AI coding tools. Claude-code is a $1B run rate product six month after launch. The latest Claude Opus 4.5 model is several times cheaper and faster than last month’s version and uses about a quarter of the number of tokens to get work done. My own benchmark saw over an hour of coding reduced to 17 minutes. The high rate of change continues. The boundary of what does/doesn’t work is pushing back fast.

Claude Code Is Anthropic’s Gateway Drug To The Enterprise

Spent my morning pairing with Claude because I had to make probably-similar-but-not-identical changes to 73 repositories. Starting with analysis, planning and reviews which was so much easier at scale with assistance. My successful workflows are the ones where I think about how to keep myself in the loop, and I review/edit everything before I run it - but ask for review and feedback as I go. The scripts are a mess but it’s disposable code so as long as it’s readable, that’s fine!

AI is Dumber on Mondays
It's Monday morning. My coffee is hot, my IDE is open, and Claude Code just suggested I fix a bug by... creating the exact same bug in a different file. Cursor is hallucinating function names that don't exist. Codex thinks undefined is a valid return type in TypeScript.
Did the AI catch a case of the Mondays?

Ah, to have the confidence of Claude Code. Let's see whether this confidence was misplaced.

My latest rabbit hole has been "LLM Routers"
Read and tried all the LLM Router code I could find. None of them were what I was looking for.
So I asked Claude to write what I wanted in Python. Simple and elegant. Based on a keyword search of the prompt, the prompt is sent to the proper model running in ollama. Seems to work.

"Digital Camouflage": The LLVM Challenge in LLM-Based Malware Detection
Large Language Models (LLMs) have emerged as promising tools for malware detection by analyzing code semantics, identifying vulnerabilities, and adapting to evolving threats. However, their reliability under adversarial compiler-level obfuscation is yet to be discovered. In this study, we empirically evaluate the robustness of three state-of-the-art LLMs: ChatGPT-4o, Gemini Flash 2.5, and Claude Sonnet 4 against compiler-level obfuscation techniques implemented via the LLVM infrastructure. Thes…

Protostellar Jets in Star Cluster Formation and Evolution: I. Implementation and Initial Results
Stars form in clusters from the gravitational collapse of giant molecular clouds, which is opposed by a variety of physical processes, including stellar feedback. The interplay between these processes determines the star formation rate of the clouds. To study how feedback controls star formation, we use a numerical framework that is optimized to simulate star cluster formation and evolution. This framework, called Torch, combines the magnetohydrodynamical code FLASH with N-body and stellar evol…
