One tip I have is that once you have the diff you want to fix, start a new session and have it work on the diff fresh. They’ve improved this, but it’s still the case that the farther you get into context window, the dumber and less focused the model gets. I learned this from the Claude Code team themselves, who have long advised starting over rather than trying to steer a conversation that has started down a wrong pa…

Yeah, I start most of my sessions now with “read the diff between this branch and main”. Seems like it grounds and focuses it.

One thing that seems important is to have the agent write down their plan and any useful memory in markdown files, so that further invocations can just read from it

When Anthropic said they wouldn't sell LLMs to the government for mass surveillance or autonomous killing machines, and got labeled a supply chain risk as a result, OpenAI told the public they have the same policy as Anthropic while inking a deal with the government that clearly means "actually we will sell you LLMs for mass surveillance or autonomous killing machines but only if you tell us it's legal". If you alrea…

I'm not some kind of OpenAI or Pentagon fanboy, but it's pretty easy to for me to understand why a buyer of a critical technology wants to be free to use it however they want, within the law, and not subject to veto from another entity's political opinions. It sounds perfectly reasonable to me for the military to want to decide its uses of technologies it purchases itself. It's not like the military was specifically…

“Any legal use” is an exceptionally broad framework, and after the FISA “warrants,” it would appear it is incumbent on private companies to prevent breaches of the US constitution, as the government will often do almost anything in the name of “national security,” inalienable rights against search and seizure be damned.

If it isn’t written in the contract, it can and will be worked around. You learn that very quickly in your first sale to a large enterprise or government customer.

Anthropic was defending the US constitution against the whims of the government, which has shown that it is happy to break the law when convenient and whenever it deems necessary.

Note: I used to work in the IC. I have absolutely nothing against the government. I am a patriot. It is precisely for those reasons, though, that I think Anthropic did the right thing here by sticking to their guns. And the idiotic “supply chain risk” designation will be thrown out in court trivially.

It's also identical to what Claude Code does if you put it in plan mode (bound to key), at least in my experience.

My annoyance with plan mode is where it sticks the .md file, kind of hides it away which makes it annoying to clear context and start up a new phase from the PLAN file. But that might just be a skill issue on my end

After creating the plan in Plan mode (+Thinking) I ask Claude to move the plan .md file to /docs/plans folder inside the repo.

Open a new chat with Opus, thinking mode is off. Because no need when we have detailed plan.

Now the plan file is always reachable, so when the context limit is narrowing, mostly around 50%, I ask Claude to update the plan with the progress, and move to a new chat @pointing the plan file and it continue executing without any issue.

I hear what you're saying, but for a lot of people coding isn't something we can throw 40+ hours per week at. My main job is running a small eComm business, and I have to both develop software automations for the office (to improve productivity long-term) while also doing non-coding day to day tasks. On top of this, I maintain an open source project after hours. I've also got a young family with 3 kids. I'm not sayin…

100% agree with this, as much as I hate the term "game-changer"... it truly is, I'm working on projects that I've always wanted to do but never had the capacity (or money to pay a small team of devs to build something)-- all these things that you thought you'd never have a chance to do, are suddenly now real and completely possible. I know there's a lot of AI haters out there but I'm pretty sure in time, all devs wil…

If anyone thought there was value to those projects they would have paid for it before.

Sample of one and all that, but it's way, way more sloppy than it used to be for me.

To the extent, that I have started making manual fixes in the code - I haven't had to stoop to this in 2 months.

Max subscription, 100k LOC codebases more or less (frontend and backend - same observations).

Opus 4.6 is nuts. Everything I throw at it works. Frontend, backend, algorithms—it does not matter. I start with a PRD, ask for a step-by-step plan, and just execute on each step at a time. Sometimes ideas are dumb, but checking and guiding step by step helps it ship working things in hours. It was also the first AI I felt, "Damn, this thing is smarter than me."

1000% agree. It's also easy to talk to it about something you're not sure it said and derive a better, more elegant solution with simple questioning.

Gemini 3.1 also gives me these vibes.

I am starting to believe it’s not OPUS but developers getting better at using LLMs across the board. And not realizing they are just getting much better at using these tools. I also thought it was OPUS 4.5 (also tested a lot with 4.6) and then in February switched to only using auto mode in the coding IDEs. They do not use OPUS (most of the times), and I’m ending up with a similar result after a very rough learning c…

I had similar thoughts regarding "we are simply getting better at using them", but the man I tried Gemini again and reconsidered.

Hot take... the 1MM context degrades performance drastically.

Same. First time in 2 months that I found it easier to fix the bugs it created manually, rather than get it to fix. Its google-code-CLI-on-gemini-2.5 level bad for me today. Meaning, almost comically bad.

Friends, just write the code. It’s not that hard.

You're witnessing the rise of the Developer Technician or Software Technician. They can get a machine to print out an application but you will still need an engineer to know how it works or to get it working. This used to be juniors learning to be senior devs/engineers. Now it is a split between technicians and engineers. The market will be up shit creek when all their technicians can't vibe code their way out of not understanding the code.
