@axadrn @adamdotdev Was a Claude Code enthusiast for a long time but open code just produces better results for me using the same models. Don’t know why but it it follows my instructions better, is fast and great in tool calling. UI is better and switching between providers is super easy. Try it.

[David Maier @DavidAMaier]

Wooo, existential crisis over.

Claude Opus 4.5 is now available in Claude Code for Pro users.

Pro users can select Opus using the /model command in their terminal.

[David Maier @DavidAMaier]

@MaximeRivest It took me a while to fully understand the impact of this week's releases.

In systems science we think a lot about tipping points, and it feels like Opus 4.5 and Nano Banana Pro might represent the moment of passing one, leading to exciting changes in system state.

Crazy thing I've discovered today: Databases are much better for storing data than text files.. :o

Whats probably a bit more interesting is that coding agents are very good in using sqlite and telling claude to use an sqlite db for storing structured information that it should use later on is very convenient.

@audiencon Hey engagement farmer, where is the product?

Or don’t you care about your X followers anymore now that you are rich?

[David Maier @DavidAMaier]

@audiencon Bro I can give you that in 5min without AI.

Generating 1M in hosting cost is such a no brainer if you know use AWS…

[David Maier @DavidAMaier]

@dani_avila7 Or he’s thinking. “Ahh better not ask this guy, what should he tell me that I don’t know better”.. 🤷‍♀️

[David Maier @DavidAMaier]

@ryanvogel @elysiaJS @orpc @hono I’ve used Elysia in several projects (although mostly toy project but one is used heavily) and I really enjoyed it. Just the right layer of abstraction.

Claude skills is cool! I hear people saying that @AnthropicAI focuses too much on side quests instead of building better cheaper faster models.

I don’t think so. They understood that creating the best coding model is useless if doesn’t have access to a high quality agent ecosystem and they’ve committed to building this ecosystem in the open.

I have several years of experience as senior software dev and I recently finished my MSc. in innovation management. This is my take from an interdisciplinary perspective.

If it wasn’t for Anthropic, CLI coding environments would not be what they are today. Codex, opencode, Gemini CLI etc are great (some more, some less) and they are essential to drive innovation, but we cannot appreciate enough what Anthropic has given to us.

They had the guts to invest when there was no reliable indication that CLI tools could be a serious market in a world where devs spend their days in IDEs. They still saw the potential and went for radical innovation.

Then they created standards like MCP in a way that separates their financial interests completely from the concept. It works perfectly well with any other model and coding tool and it made everyone better off. It’s also incredibly easy to use claude code with other coding models, further confirming their dedication to open innovation.

And they keep pushing. They look at people’s needs and they search for universal solutions.

Claude Skills may seem like a trivial solution but that is exactly the beauty of it. Devs at Anthropic learned from the trouble that comme with MCPs. They read the papers about context rot and recognized that developers need a more lightweight way to connect their coding agent with the tools that are already present on their system as fully configured CLI tools or to provide context for reoccurring complex tasks that don’t need external tools. Without polluting context.

MCPs have their right of existence. Remote MCPs are hilarious and define a unified structure that allows developers to give agents (remote) tool access across ecosystems. It’s a turning point and I think this ecosystem is only in its very beginning. When I look at well developed MCP servers like the @linear MCP, I can only imagine the bright future this technology offers for agents.

But to be honest I see the future of MCPs mainly with task dedicated production agents. Less with general purpose coding agents. Professional developers usually have their tools at hand and can access them via cli commands. They also have an idea of how they want these tools to be utilized. There is no need for an additional abstraction layer defined by the scary and powerful term “server”. If a coding agent should access my Postgres dev DB, it should just use the pg cli tool and it knows how to do that without adding 20k tokens every time I use Claude Code.

Of course you could just add the instructions on how you want your cli tools to be used to https://t.co/wOOUZxxUmx in every project. But that leads to context pollution again and lacks the joy of reusability we devs love so much.

Agent skills are a simple solution that just add the necessary structure to already existing solutions to makes them reusable and extendable. In innovation science we know that invention != innovation and real innovation often requires looking at ideas others have invented. Then taking a step back to see how they can be adapted to allow for large scale integration makes them a real innovation.

This became a bit long, maybe I should better start blogging. Btw. I have no affiliation with Anthropic but I felt the need to highlight how their attitude of open innovation drives progress in one of the most exciting topics today. Open weight models would be nice though.. ;D

I you made it through this long ass post, I’d love to hear your opinions.

Claude Code Weekly Round Up

A big week for shipping!

Besides Haiku 4.5, we added support for Claude Skills, gave Claude a new tool for asking interactive questions, added an ‘Explore’ subagent, auto-background long running tasks and fixed several bugs.

[David Maier @DavidAMaier]

Damn, I need this. Don’t know what for, but I need it urgently.

https://t.co/8E5GrplzFK

[David Maier @DavidAMaier]

@Adityapandeydev Gleam

[David Maier @DavidAMaier]

Haiku 4.5 makes working on a single file, making micro edits much more fun because of its fast response time.

This feels a bit like coding in the old days, this feeling of having full control. But with less mental effort and faster.

[David Maier @DavidAMaier]

@soychotic That why I’m currently doing my PhD..

[David Maier @DavidAMaier]

I still have only a very small number of followers (shout out to these cool people) but it is really a bit unsettling that I got about 0 new followers a week before I subscribed to X premium and now it’s two or three a day.

My posting behavior did not change at all.

They really made this a read only thing for non paying users. Elons radical way to go through this can teach us many lessons.

This doesn’t mean that I’m happy with it, took away a lot of the spirit and the approach of “it’s free speech, but if you don’t pay you speak in an empty room” is at least questionable, but from a business perspective they have my respect, because there is no sign for me that a competitor will take over soon and I also don’t see many people on here without blue badges.

[David Maier @DavidAMaier]

@mattpocockuk Rehab programs for AI addicted software devs might be a market gap..
Maybe a good idea for your next course @mattpocockuk ? 😉

[David Maier @DavidAMaier]

A valid observation - indeed - but let’s delve into the epistemological framework of your statement - what does it truly mean to “have nothing to say”?

[Dan Kulkov @DanKulkov]

STOP REPLYING WITH AI

JUST STOP

DON'T REPLY IF YOU HAVE NOTHING TO SAY

STOP THIS!!!!!!!!!!!!!!!!!!!

[David Maier @DavidAMaier]

Anyone has an idea how I can have two different claude codes on my system? One that uses GLM 4.6 and one with Claude?

Background:
I've tried to make claude code convert my masterthesis into an HTML file that links every citation to the exact location in the original paper that justifies the claim.

When it came to converting the papers to HTML files that I can link to with precise locations, I noticed that claude is a bit strict in terms of processing copyright protected material. As expected, GLM does not really care about that.

Now I want to have both options available without having to edit .claude.json everytime I want to switch.

[David Maier @DavidAMaier]

Love this sync engine.

Hope they never remove the CRUD mutators though as they state in the docs. I sometimes use Zero for prototyping and for more complex data exploration apps that are only for myself. And for this its so useful to just have the full DB in the frontend.

[Zero @zero__ms]

This is quite exciting! Makes the Claude code / codex combination even more compelling.

- Haiku for quick, well defined tasks and brainstorming
- Sonnet for planing (and text writing)
- codex for larger refactors based on sonnets plans and tasks on large files (eg. “check all references in this scientific paper, hand me the exact supporting text passage for each”)

[swyx @swyx]

"more than twice the speed" is underselling Haiku tbh

built a way to directly compare Sonnet v Haiku 4.5 and it's roughly 3.5x faster, but the UX feels SO much better because Haiku stays inside the "flow window".

obviously end to end latency varies a lot so Ant can't report a real number without production usage but you should try heads up comparisons

[David Maier @DavidAMaier]

Made the same mistake once. Microservices can be a nice architecture. But the main problem they’re solving has to do with too many people working on the same thing. Too many people working on something is usually not the problem in startups.

So you’re not solving a non existent problem by introducing a LOT of overhead. Better try to create your monolith in a modular way. Create internal boundaries that can help splitting out microservices later on.

[Yatish Mehta @yatish_me]

At a past company, the head of engineering and the principal engineers decided to break our Ruby on Rails application into a Go microservices mesh.

They created very detailed design documents and architecture diagrams. They went all out and used Kubernetes, gRPC, service templates, the whole shebang.

The whole senior engineering leadership came from Amazon, where they were used to each team owning a distinct service. They tried to apply that model directly. But our issues were with code ownership and poor domain modeling.

The entire application could have run on just a handful of EC2 instances.

What was the result?

Five years later, 70% of the application is still running on the Ruby on Rails monolith. Never completed the migration. But now they have to maintain two systems.

None of the original leadership works there anymore.
