Clinejection — Compromising Cline's Production Releases just by Prompting an Issue Triager | Adnan Khan - Security Research Clinejection — Compromising Cline's Production Releases just by Prompting an Issue Triager - Security research by adnanthekhan

Just amazed how sophisticated attackers can be...

- inject a malicious prompt into Claude via a GitHub issue title
- evect the GitHub Actions cache by overloading it with garbage
- inject code into Cline to install OpenClaw on victims machines

CCC vs GCC A Guide to comparing Claude Code Compiler with GCC

The Claude C Compiler was fascinating but reading this does show that it's fairly elementry in its approach.
Not sure if it's a prompting issue or that there's not enough weight towards compiler optimizations in the LLMs?

That said, it still requires a lot of solid, good knowledge in software engineering to create this harness.
Far from vibe coding.

Building a C compiler with a team of parallel Claudes Anthropic is an AI safety and research company that's working to build reliable, interpretable, and steerable AI systems.

Not only are the results fascinating, but the steps the engineer had to take plays as a good reference.
It's also encouraging that the steps an Anthropic researcher is taking are nothing special and it's something humans would have had to do anyways.

AGENTS.md AGENTS.md is a simple, open format for guiding coding agents. Think of it as a README for agents.

Interesting result on how having an index in AGENTS.md performed better than having Skills.
AGENTS.md feels more natural as it's about adding context whereas Skills is more an action.

Why We've Tried to Replace Developers Every Decade Since 1969 Every decade brings new promises: this time, we'll finally make software development simple enough that we won't need so many developers. From COBOL to AI, the pattern repeats. Business leaders gro...

> But invest primarily in your people’s ability to think clearly about complexity.

We've gone through many iterations of the "developers are unnecessary" yet never happened.
We're problem solvers tackling complexity and that never goes away.

Anthropic has their original CLAUDE.md so seems like it's OpenAI's move to make AGENTS.md the defacto-standard.

Not sure if that means much though given it's really just natural language that gets thrown into the prompt🤔

OpenAI co-founds the Agentic AI Foundation under the Linux Foundation AAIF aims to advance open-source agentic AI with the donation of standards including OpenAI’s AGENTS.md

Been reloading OpenAI's news all day to see GPT 5.2 release and found this news:

They're also going to contribute AGENTS.md to the foundation.

This "veto test" is so simple yet so spot on.

"the “veto test” used by Silicon Valley Product Group: If a person has veto power over your project or can stop it from launching, they’re a stakeholder you need to engage."

This is really unfortunate that the owner lacked respect to the contributer.

2 Years of ML vs. 1 Month of Prompting

This a good lesson on
- how previous conceptions may not be adequate today
- it's not always about using the absolute best model (ROI matters)

High performers tend to be ones who constantly re-evaulate their process (i.e. "how" they work) and keep on improving it.

Beyond Vibe Coding with Addy Osmani Google’s Head of Chrome Developer Experience, Addy Osmani, shares how AI is transforming the way we code—accelerating development while still relying on human expertise to ensure real quality.

Everyone should listen to what Addy has to say about AI coding.
Very thoughtful and level-headed but yet very optimistic about AI.

The PSF has withdrawn a $1.5 million proposal to US government grant program

Just donated to PSF.

Sad to see they had to withdraw their proposal to the US government but I think it's the right decision.
My donations small but just wanted show some people are behind them.

The small things make a big difference.

Been posting the same message to X, Bluesky, Threads, Mastodon. Some apps retry properly even in the background.
You can always resend it yourself but it's so much more pleasant to use.

- LLMs can be helpful for software development.
- LLMs for software development are being oversold by some people who stand to gain a lot of money from them.
- LLMs for software development are being undersold by some people who have decided for various reasons that they do not like the technology.

What makes Claude Code so damn good (and how to recreate that magic in your agent)!? Claude Code is the most delightful AI agent/workflow I have used so far. Not only does it make targeted edits or vibe coding throwaway tools less annoying, ...

Fascinating deep-dive into Claude Code's architecture.

Simple grep commands prefered over RAG for code search and uses smaller models for 50% of operations.

Sometimes the elegant solution beats the sophisticated one.

Feels like it's becoming increasingly important to have "good taste" of what's better for your codebase.

It used to be that you had to spend time on code edits before you could tell but with LLMs like Claude Code, it's way easier to try it out.

Updates to Apple's On-Device and Server Foundation Language Models With Apple Intelligence, we're integrating powerful generative AI right into the apps and experiences people use every day, all while…

Apple's new on-device LLM is post-trained on a special data structure that is and to be generated by the developer based on a Swift Generable annotation.

This is interesting.
First time I've seen an LLM integrated with a programming language in this way.

I'm starting to think static typing (or rather stricter rules enforced by the compiler) is the way to go when it comes to AI tools (Cursor, Cline, Claude Code, etc).
The compiler can pretty much direct the AI agent to apply the changes needed.

Wow...Claude Code has just upgraded my GitHub helper command written in Haskell from 9.10.1 to 9.12.1 and actually used it to create the pull request merely by reading the code (and maybe the help message it executed during the session).
