The most famous public Facebook-ism is "Move fast and break things."
"Done is better than perfect." "Code wins arguments."
I've found introducing concepts like that in my AGENTS.md / claude.md file tend to drive the AI toward agreeing with me.

Pretty wild to think Apple was so far ahead on Siri, and the current state of Apple's personal assistant products compared to something like ChatGPT.
Might be the biggest technology miss of all time.

My codex system prompt (also symlinked to claude)
I added the team culture section recently. It seems to be helping it ask fewer “why don’t we add x as well? Let me know if you need y” type questions

How do we feel about the personification of ai assistants? ie Claude vs ChatGPT?
I'm honestly not sure... pros and cons for each. What do you think?

I don't think people fully appreciate just how much better GPT5 is than GPT4. Chatgpt doesn't really showcase how much better it is, though you can see it if you squint.
GPT5 agents are just otherworldly at staying on task.

I have to convince codex to rubberduck with me to fix the most complex problems. Like I don’t really know what’s going on with this weird type inference issue that i’m having, but getting codex to write a little lab notebook thing and then keep working on it, it fixes it.

I want to be the Rakim of AI.
Prompts / AI engineering from today will look like the Fresh Prince. I want to introduce flow into the AI world.
Like nobody is going to get this tweet, and that's ok. :)

I think there's a concept i'm landing on... "Inference Engineer." Context engineering is about how to make the whole pipeline good, give the ai the right context, etc. Inference engineering would be about considering how specific information flows into an LLM.

So we run our standups via claude code as facilitator (it gathers the data, records info, etc.)
Today it was ineffective b/c we updated a different runbook that caused it to not work right.
We don't have evals on it. It's required for anything mission critical it turns out.

Launching a startup as a remote team is such a bad idea.
Honestly it'd be better to have a single person launch something, then add team members progressively than try to coordinate multiple people across multiple timezones.
Especially in the age of AI.

Everything you need to know about GitHub:
Its homepage is literally unusable and completely ignored.
Its default actions viewer is a node based thing to handle thousands of connected jobs.
Please someone help us. As bad as sourceforge was, github is now as bad.

I know a lot of people are annoyed by the summarized thought traces from LLMs, but as someone who has deep empathy and a history of trauma, I can tell you the raw thought traces are emotionally draining sometimes.

My read on the GPT5 launch is a consensus: Meh.
I think that's wrong though. Think about the evolution thusfar:
GPT3 was like "wow these sentences are coherent!" 3.5 was like "wow this is actually useful!" 4 was like "Whoa it's useful and doesn't hallucinate usually!"

Don't always use the highest thinking LLM to do your job. The pattern I've found that works for code:
GPT-5 minimum for finding all the files required and building the context. Low for writing initial code / unit tests / docs
If low gets stuck, go to medium.
When to use high?

Codex's actual output is just simply better than Claude Code. I’m consistently using low, then having high go back and code review, and it just looks like code that I’d be proud of writing at FB. It’s insane.

Claude Code does A LOT more classification before starting tasks than Codex.
That’s what makes it feel so fast.
Right now, it seems like gpt is just using whatever effort level you specify and doing everything in that mode.

Codex is like a car: Build the context with minimal mostly, then shift to low for light code, then medium when you actually kick off code if you have tests so that it can iterate through, then high for yolo.
Shift gears at the right time or you go way slower than you’d like

i will say that all the things i invested in to make claude work more effectively are helping with gpt. I’m going to explicitly stay out of all claude-only tooling (subagents most namely)

also a lot of the ceremony in claude code is because the model isn’t as good. permission settings, hooks, subagents, all of that is kind of hacking over the fact that the model just isn’t as good as it could be

Going to do a claude code bootcamp where i build a production quality application with claude code mostly using context engineering. Invite in the thread.
