- Complexity Wall (noun) The point where a system becomes so complex that there is no intelligence left to make progress in a reasonable time.
- Agentic coding won't work with your PR workflow. It will incentivize larger, crappier, unreviewable, LGTM batches to hit the complexity wall fast. We need is a workflow that enables MMMSSMF (Many More, Much Smaller Steps, More Frequently), so that we can speed up while still being able to review it.
- Reposted by Gregor RieglerSpec-first approach is counterproductive when using AI. What AI brings to the table is superpowers to engage in serious exploratory, experimental approach to engineering.
- In agentic coding, don't obsess over rules. Build tight feedback loops and iterate. You gain far more from iteration than from rules.

- Given that we now understand we’ve been training AI to guess rather than to admit when it does not know, it should make us reflect on exams and the way we educate people.
- We never needed a senior doing the work of 10 juniors. What we need is a senior doing the work of a senior, together with a junior.
- I tell my agents to conclude with their confidence level. GPT-5 almost never gives me [10/10 confidence], while Claude Sonnet 4 does it very often. To think higher confidence is better would be foolish.

- Reposted by Gregor RieglerNo other POTUS in history would make such flippant posts and statements about attacking an American city. The fact that this stuff is commonplace in the current administration and tolerated by so many is testimony to the moral rot we are suffering as a nation.
- Considering the effort I spend making sure the agent only reads what it has to and to bring this into the simplest form, eliminating all noise, and to ration this in small as can be contexts. It makes me wonder. Why didn't we do those things earlier - for ourselves? Do we not care?
- A lot of people were asking about examples for my "Augmented Coding - A Pattern Language" post. So I was iterating over it and added some. I also added new patterns. gregorriegler.com/2025/07/12/a...

- Reposted by Gregor RieglerA problem with modern LLMs is that they are so convincingly anthropomorphic now that when they produce wildly incorrect responses like this one, my reaction isn't "oh, I found a bug", it's "you're a lying sack of shit!"... and that level of emotional reaction to a piece of code really isn't healthy.
- Reposted by Gregor RieglerI expect that consumer-facing AI programs will continue to improve and they may become much more useful tools for everyday life in the future. But I think it was a disastrous mistake that today’s models were taught to be convincing before they were taught to be right.
- When you're faced with a problem, don't think: "What's a possible solution?" Think: "What information am I missing?"

- I had a lot of fun doing augmented coding as of recent and decided to capture my learnings in a new blogpost. Here is what I learned: Augmented Coding - A Pattern Language gregorriegler.com/2025/07/12/a...
- Pro Augmented Coding Tips: -Define the process using .md -Keep context small -The agent creates it's next context -Preserve cross-context memory in .md -Keep the code running -No new code without a failing test -Filter needless script output -Small steps and iterate -Iterate on your process files

- And the capabilities of refactoring tools are still supbar on extract method. Even the best. E.g.: It does not ask me whether I first want to split those variables.
- I’m close to being able to explain why Extract Function is the most-used refactoring. Not sure why I didn’t ask this question for 30 years but here we are. #TidyTogether

- Software engineering is a decision tree. Each decision yields learning. Learning shapes future decisions. No decision? No learning. Some decisions are harmful. Knowledge is our greatest asset. A good process maximizes learning, preserves knowledge, and minimizes the damage of harmful decisions.
- We can't always prevent harmful decisions, but we can reduce its damage. We do that by surfacing them earlier, by deferring them until we have better evidence, or by making them reversible. But before all of that, we want to enable decisions.
