I build things with code since 2008.
~80 projects on GitHub

[Bartek Filipiuk @bartfilipiuk]

You may know the problem.

If I started prompting Claude Code in more than 2 terminals (split in 4 windows)… Sometimes I lost track of which project was which.

And you know that moment when Claude gets confused and starts trying to help You with the wrong project? Funny :P

So i just build CodeHelm for myself. Local app, it's open source now.

Terminals by project, split window, tabs which could be renamed. Session history etc.
Im using it everyday.
Bugs? Yes but it's quite stable

I build a game using Claude Code but it's not impressive anymore so i make a Lofi Vibe Coding Music set from the session messages :P

The build by the numbers:

-> 1,557 tool calls
-> 479 files edited
-> 68 prompts
-> 4,000 events
~16h of coding compressed into 90 min (across 4 days)

Kurs tworzenia aplikacji webowych w Claude Code.
Za darmo, tutaj, zero subscription, no emails :P

Start kursu:

1. Odpal Claude Code, model Opus 4.8, auto-mode.
2. Wpisz co chcesz: "Chce aplikacje co robi XYZ, użyj brainstorm, supermoce, spec, writing-plan, TDD i inne magiczne pluginy, żebyśmy ustalili scope"

(XYZ jest obojętne, możesz dać swoją
speckę poprzez @plik.md lub napisać jednym zdaniem :P

Najważniejsze to wiedzieć co i po co się buduje.

3. Claude będzie z tobą pisał, pogadaj z nim, odpowiedz na pytania, zastanow się co i jak, czytaj jak czegoś nie kumasz.
4. Claude napisz ci specke, przeczytaj ją i napisz, że jest ok :P
5. Claude napisze plan.
6. Jak zapomniałeś to napisz mu, że każdy epic/task ma mieć weryfikacje security, OWASP, WCAG itp. do tego każ mu odpalic code-review i simplify (chyba, że masz swoje skille do tego (ja mam hehe) i każ je mu odpalić.
7. Jak wszystko sie zgadza i dokładnie przeczytałeś plan to Claude ci zaproponuje flow kodowania - wybierz Subagent-driven z opus 4.8
8. Czekaj, zależnie od wielkości projektu - 30min - 3h (lub dłużej)
9. Odpal projekt, zobacz czy jest ok, jak nie jest to powiedz to Claude
10. Działa, dla pewnosci powiedz mu, że ma się pobawić w white hat hackera i niech znajdzie podatności w systemie i jak znajdzie nich fixuje.
11. Gotowe, apka loklanie działa teraz tylko deploy :P Jak nie wiesz co to napisz to Claude i on cie pokieruje, celuj w VPS na Hetznerze niż jakieś Vercel i Supabase - jak Twoja apka wystrzeli to łatwiej i taniej będzie Ci skalować lub przenosić na coś podobnego :P

Pro tipy.
Możesz zapuścić kodowanie apek na noc, uzywaj /loop - jak już masz cała specke i plan to napisz Claudowi żeby zbudował prompt do loopa aby nakodować wszystko w nocy, niech zrobi jedną iteracje testowo żeby ewentualnie poprawić loop prompt.

Jak masz Max 20x to możesz dwie apki na raz robić (przez cały tydzień) :P
Tak, nie masz pojęcia co będzie w kodzie no ale możesz zobaczyć.
Buduj skille na podstawie swojego flow i je poprawiaj.
Głównie skup się na security i czystym kodzie (SOLID itp) - jest łatwiej testować i później agent AI też ma łatwiej jak przyjdzie do zmian.

Koniec kursu.

I'm trying my hardest to push the limits in Claude Code and Opus 4.8...

Maybe that day has finally arrived :P - 683 agents.

I'm collecting and preparing data for training a local model.

The first training of Gemma 4 12B on a real dataset was promising, and I've improved the system for local code review in the Drupal CMS (PHP). Now I want to see if I can get more out of it.

We're using a slightly modified autoresearch from Karpathy: https://t.co/lb2kqY4hpf

The model itself works very well, even on "lower-end" hardware.

I traded scrolling through social media for scrolling and prompting Claude Code on my phone :)

It's not easy to be a good father of two sons and fully realize "myself" and my ambitions; in fact, I'd say it's impossible :D

I have a ton of ideas floating around in my head that I want to translate into code and apps.

I put many of them aside and only work on the ones that seem most interesting and have potential. I don't spend a ton of time on them either, because I simply don't have much time.

But I've developed a system and skills (Claude Code) to keep things moving forward in a meaningful way.

I have an idea, I launch the idea-to-MVP skill. In short,
- research (workflows)
- rationale
- complexity
- stack, spec, plan
- coding (subagent-driven, TDD, code review, security, etc. + Opus 4.8)
- e2e testing (the agent does it) - if it finds something, it immediately fixes and retests.

(I use the built-in skills plus my own at every stage)

I'm actively involved in everything before coding.
Opus codes everything that needs to be done.

In a given Claude Code window, I have Remote Control activated, and from there I can push the agent from my phone. So when I want a quick dopamine rush and to move things forward, I don't use X/Li, I use Claude Code ;-)

If something requires my 100% attention, I tackle it in the morning or evening, if I have the time.

[Bartek Filipiuk @bartfilipiuk]

10 hours of Claude Code activity during spec writing, research and coding. 24k lines of code. Lot of commits.

I created a 1vs1 online quiz like game, because i can and want :) Free to play at https://t.co/EbMi47gs3j (beta)

Thanks to AI, agents and vibe coding, i can dump all my ideas from brain to code quicker than ever.

All data about project, links, stack, architecture, course - how to build own, security issues found after coding and lot more: https://t.co/fvopzcV9yL (free, no emails etc)

@levelsio i have 5 (lol) shares from june 2022 :D +330%

[Bartek Filipiuk @bartfilipiuk]

Unpopular opinion on cursing at AI agents.
If you're mad at an AI agent for doing something "wrong," not the way you wanted, it's usually because you don't actually know what "right" looks like.

[Bartek Filipiuk @bartfilipiuk]

Claude code and /remote-control using on your phone is the new way of distraction, but could be productive. Prove me wrong 😅

Instead of enjoing walk you prompting and checking your agent 🤪

[Bartek Filipiuk @bartfilipiuk]

@Kavyabuildss its just looks like a pre-ai-coding standard legacy project where new dev team take it over from previous team :P Code is mess, dead code, duplications etc. Then experienced SWE need to fix it. Same here on post-ai-coding era but faster.

[Bartek Filipiuk @bartfilipiuk]

Lot of devs just switched to Codex, but I completely forgot.

Claude Code is still my daily driver.

Not saying Codex is worse (it’s probably better in some cases), but man, Im addicted to the flow and creativity of Opus 4.7.

Give it a spec + docs + tech stack + some arch decision, then it just can run 2+ hours straight and spits out a ready-to-use app in almost one shot.

After that I just use “superpowers” (cc plugin) and go play with my kids.

Are you Codex or Claude Code team :P (or both?)

#AICoding #ClaudeCode #Codex

[Bartek Filipiuk @bartfilipiuk]

i really like the focus mode but it's little bit buggy when im switch it off - little mess on currently open terminal ...

And the crons (scheduled actions), experimental.
The real prompting of claude in open terminal (you choose) not the claude -p command

[Bartek Filipiuk @bartfilipiuk]

You may know the problem.

If I started prompting Claude Code in more than 2 terminals (split in 4 windows)… Sometimes I lost track of which project was which.

@levelsio yes! im TCPing and SSHing also ;-)

[Bartek Filipiuk @bartfilipiuk]

ok, vibe coding with #ai @windsurf_ai / @cursor_ai is a creative bomb.

I like it :) Solar system travel.
html, js and css. Textures generated by ai, not so pro but seems fine.

[Bartek Filipiuk @bartfilipiuk]

@rileybrown_ai @anshnanda Hi @rileybrown_ai great work with building apps. Just a question, summary is done via transcription provided by Youtube or You have something listening the video and create a transcription?

also have some non-public projects like app for kids to recognize animals in english (learning english) where also i have hand written numbers recognition using canvas and trained model with tensorflow - it was written in python by windsurf

and may other smaller stuff ...

#WindsurfGiveaway

[Bartek Filipiuk @bartfilipiuk]

How many of these applications that people write using AI editors like @cursor_ai or @windsurf_ai are worth anything? I use both, they are amazing and speed up my work.

I'm not talking about writing a calculator in 15 minutes, but something that is at least a little more complicated.

I write slightly more complex things in PHP and Drupal, and if I didn't know how to code and didn't understand what's going on inside (in ai generated code), I'd be in deep shit.
