Three big "state of the industry"reports landed this week, and they tell two very different stories: At the frontier, agents now open more pull requests than humans. In the median company, an AI seat ...

The question moved this week. Nobody serious is still asking whether agents can write the code: the people shipping the most are asking who verifies it, how cheaply, and how to move humans on top of t...

A stealth lab refreshes interest in narrow AI. Agentic coding keeps stressing CI platform infrastructure. The shape of the software factory is converging. Fundamentals matter more than ever. Pacing th...

Multiple model launches took the headlines, none will change how you work on Monday. What might: an engineer shipping 2,000 PRs a month explained their actual method, AWS published what happens when f...

This week: code review collapsed, a linter that only flags problems turns out to be half a tool, and every repo is a software factory now. Cheap code made architecture visible rather than optional, to...

Anthropic shipped an invisible watermark into every Claude model launched after August 2, but how effective is it really? The AI productivity gain has a half-life, and the slop it leaves behind does n...

Will CI/CD survive agents? Steve Yegge and Jez Humble seem to disagree. OpenAI's model cracked ten long-open mathematical problems, a mathematician explained precisely what it still cannot do. Datadog...

Leading the science of software success

Code is the result of hundreds of decisions an hour, coding agents that makes them in your stead are not saving you any time. Big tech is waking up to the fact that tokenmaxxing only results in higher...

OpenAI ran a negative 122% operating margin in Q1, Andrej Karpathy reframed his own term "vibe coding" as "raising the floor for everyone", putting it in sharp contrast with "agentic engineering". Gia...

The honeymoon ended in stereo this week. More hard data on AI velocity landed (10-15%, not the 3X your CEO has been quoting), the pricing reset got calendar entries, the techlash got organised into ac...

This week, the receipts arrived from every direction at once. Thoughtworks' Tech Radar reads like a warning letter, frontier models silently corrupt a quarter of what you delegate to them, and the com...

Two independent datasets landed this week that make it hard to keep presenting AI productivity as a global rising tide, and in the same seven days DHH, Charity Majors, Fowler and Beck all arrived at the same uncomfortable conclusion: the window for rational skepticism has closed and its time for

weekly agentic engineering digests. Curated for practitioners by practitioners

RTK cuts 80-99% of token waste from build output, git commands, and test runs. Here's how to get the automatic hook working on Windows, since the installer won't do it for you.

I don't think we have five years before agentic coding becomes the mainstream context in which professional software development happens. I think we're talking about two or three. Possibly less. If t...

This one goes out to all the testing neophytes who only recently realized (https://simonwillison.net/guides/agentic-engineering-patterns/red-green-tdd/) that it's useful to have an automated means of verifying their code does what it claims to do. For the last month, I've been working on prove_it (https://github.com/searls/prove_it), a framework for building quality harnesses for Claude Code (https://claude.com/product/claude-code)—primarily via its hooks system (https://code.claude.com/docs/en/hooks). In a recent release, I added TDD enforcement to its default configuration. First, it injects a test-first development approach into every plan Claude generates. Then, a PreToolUse hook follows up with permissionDecisionReason reminders whenever the agent deviates from the one true path (e.g., repeatedly edits source files without touching any tests, never runs a test to see it fail, etc.).

Breaking API migrations, hidden coupling, and large-scale rewrites — done safely with AST-backed AI workflows.

AI should help us produce better code - Agentic Engineering Patterns

Twitter's latest consensus on inevitability: now that large language models can write code, everyone will become a software developer. People, you see, have problems, and software solves problems, and AI removes the barrier between people and software, therefore everyone will build their own software. It's a syllogism, after a fashion,
