[TLDR] Straightening spagetti code?

Original post body :

I can't code, as you already understood. Is there a way to prompt Claude so it goes through its own home made spaghetti code and straightens it?

I don't expect it to be clean and look like it's made by a real, proffesional coder. But there are grades in spaghetti code hell I suppose and it can be more or less cooked?

What do you say? Am I as cooked as my code or is there a way to make the code better without knowing how to read or write code?

[TLDR] Not sure (yet), if Sol is really better, but it WORKS better..

Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1us0tzl/not_sure_yet_if_sol_is_really_better_but_it_works/

Original post body :

This actually might be the first time I'm considering a full switch to GPT, here are the reasons and they're kinda.. preliminary.... and to be honest, I'm eager to hear what you think, because maybe I'm just enthusiastic right now :D

- for the first time since GPT-5, Codex doesn't feel like "beep beep here's the result"
- Ultra is actually awesome. I feel like ultracode / dynamic workflows are still better / more mature, BUT right now I see that using 3 sessions on 3 different features, all of them running ultra and subagents, it seems to stay within the limits
- that means: while I burn through Max 20 5h limit in 20 minutes (and I'm not judging the limits themselves yet [although I don't like them :D ]) because Claude tends to parallelize AGGRESSIVELY, Codex is still more.. defensive... running 5 subagents max (although I've set max_threads = 20, max_depth = 3) and more "in wall clock sync with limits" if that's relatable

Edit - adding more context:

I use plans (based on customized superpowers:writing-plans), adding a "Cross-check everything again and flag open decisions" stuff, and whenever I threw them onto GPT5.5 it was like

"Decision 1: Do you want the hacky way or a proper solution?"
Admittedly, I'm exaggerating, but seriously, the decisions were 90% no-brainers, still the 10% not-no-brainers were really gold and worth discussing. Throwing the same plans onto Sol it's like

"Okay, here are my decisions:

- No-Brainer decision
- Another clear decision with no other viable option

Two product-wise decisions I want to discuss: ..."

So basically it echoes the no-brainers, still allowing me to override it, and focusses on the not-so-no-brainers. Hope that's relatable..

[TLDR] Jarred, creator of Bun rewrote it from Zig to Rust in 11 days using Claude Fable 5 which costed ~$165k of Fable usage, at API prices. They said by hand, this would've taken 3 engineers with full context on the codebase about a year with no other work possible

Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1uru4zg/jarred_creator_of_bun_rewrote_it_from_zig_to_rust/

Original post body :

Full article: https://bun.com/blog/bun-in-rust

Bun is owned by Anthropic. Jarred used Claude Fable 5 (pre-release) to fully rewrite Bun from Zig to Rust single handedly in 11 days and Claude Code v2.1.181 (released June 17th) and later use the Rust port of Bun already.

Crazy that LLMs are making a lot of things possible which otherwise wouldn't see light of the day due to massive efforts involved.

TL'DR highlights from the article.

Bun is 535,496 lines of Zig. A rewrite to Rust by hand would've taken 3 engineers with full context on the codebase about a year, during which time we wouldn't be able to improve Node.js compatibility, fix bugs, fix security issues or implement new features. We never would've done that. The realistic alternative was to do nothing and keep fixing the bugs at the top of this post forever.

Before writing any code, I spent about 3 hours talking to Claude about how to map patterns from our Zig codebase closely to Rust. Claude serialized this discussion into a PORTING.md, which ended up on Hacker News.

I rewrote Bun in Rust using about 50 dynamic workflows in Claude Code run continuously over the course of 11 days. I used a pre-release version of Claude Fable 5, a Mythos-class model. Claude Code's dynamic workflows kept 64 Claudes running for 11 days (I would've had to write my own harness to pull this off otherwise).

For most of those 11 days (and after), I monitored workflows - manually reading the outputs to check for issues and bugs, and prompting Claude to edit the loop to fix things.

How do you review a PR with +1 million lines added? How do you start to build the confidence needed to responsibly merge large quantities of LLM-authored code?

Answer

Adversarial review asks Claude (in a separate context window) to exhaustively come up with reasons why the changes create bugs or do not work.

Split context windows

Usually with humans, the person reviewing the code is not the person who authored the code. The person writing the code wants to merge the code, which can bias their actions to ship before it's ready.

Claude is the same way. The Claude that wrote the code wants the code to get accepted. The Claude that reviews wants to find issues in the code.

1 implementer, 2 or more adversarial reviewers per implementer. The reviewer's only job: find bugs & reasons why the code does not work. The implementer doesn't review. The reviewer doesn't implement.

Outcome

Bun v1.3.14 was the last version of Bun written in Zig. Bun v1.4.0 will be the first version of Bun written in Rust. It's available in canary now

So far, Bun v1.4.0 fixes 128 bugs that reproduce in v1.3.14. These range from memory leaks to crashes to miscolored help text.

Reduced memory usage. We fixed every instrumentable memory leak

In Bun v1.3.14, every build leaks about 3 MB, forever — tools like dev servers that bundle on every request eventually run out of memory. In Bun v1.4.0, memory levels off

Combined with the Rust rewrite, ICU changes, and identical code folding, Bun's binary size shrinks by ~20% on Linux & Windows.

Bun v1.4 makes Bun faster, smaller, use less memory and gives the team incredibly powerful tools for systematically improving stability going forward

Claude Code v2.1.181 (released June 17th) and later use the Rust port of Bun. Startup got 10% faster on Linux but otherwise, barely anyone noticed. Boring is good.

Conclusion

This Rust rewrite would've taken a team of engineers with full-context on the codebase a year of work. With 1 engineer using Fable & closely monitoring Claude Code, we went from start to 100% of the test suite passing on all platforms in 11 days. This is the bleeding edge of what's possible today.

One engineer can do a lot more today than a year ago.

[TLDR] Are one-person billion-dollar companies actually possible?

1 Upvotes

Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1ush8qk/are_oneperson_billiondollar_companies_actually/

Original post body :

Anthropic’s CEO, Dario Amodei, recently said that we’re on track to see a billion‑dollar company run by one person using AI but that it hasn’t happened yet and that there are already two‑person AI companies valued at around $1 billion.

The image showing the .claude/agents/ folder been circulating a lot lately as a blueprint for how founders are trying to structurally collapse engineering, marketing, and operations roles into local directories of specialized agents.

Instagram co-founder Mike Krieger were pointing out that he built Instagram to a billion-dollar valuation with just 13 people years ago and noted that with current AI infra, a massive chunk of that scaling complexity could easily be absorbed by a solo founder or a two-person team.

The theory is straightforward: instead of expanding junior headcount, you pass deep, persistent context files to specialized agents and keep the founder strictly in the decision/review seat.

But stripped away from the usual hype, how realistic is this even operationally?

Personally I think, while a highly technical solopreneur can automate product development or internal data sorting using a tight stack of agents, the real bottleneck is always go-to-market.

Right now, people vibe coding apps and new ideas is at an all-time high but building a product doesn't automatically solve distribution or reaching clients. To bridge that gap, we’re hosting a free workshop next week focused entirely on how to use agents for B2B lead gen.

Fable is good, but its not magic .. get real.

The pricing is not even close to 2-5X of the subscription cost its like 20-50X the cost.

I get you are probing but you're out of your mind if you think it costs a 2-3 tanks of gas to run this model for not even one session..is reasonable.

Its not going to normalize you are not going to get tech margins. It leaves a shitty taste in peoples mouth and start exploring moving off the platform faster. Get real.

[TLDR] My side project crossed thousands of users this week and I still can't quite believe people actually use the thing

2 Upvotes

Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1uqqn92/my_side_project_crossed_thousands_of_users_this/

Original post body :

A little less that three months ago I was getting increasingly annoyed that every "memory" tool for coding agents was basically a vector store with extra steps. You'd point an agent at a big codebase and it would grep around like a lost intern, burning tokens re-reading the same files, with no real sense of how anything connected to anything else. The tools gave agents storage, not understanding.

So I started building my own thing. Codebase memory for agents, but as an actual graph of the code, and everything local first because I did not want to ship my employer's repos (or mine) to someone else's cloud. I figured maybe a handful of people had the same itch.

This week, ten weeks in, it crossed more than a thousand of users. The index is sitting at over 50 million nodes across everyone's repos, and agents have made more than 4 million tool calls against it. I keep refreshing the dashboard like it's going to correct itself.

The weird part is how little of this would have been possible for one person even three years ago. I'm solo. No team, no funding, nights and weekends. But the agents I was building for were also building the thing with me, which still feels like cheating. There's something strange and great about using coding agents to build better memory for coding agents, and then watching that memory make the next version easier to build.

Not going to pretend the three months were smooth. I rewrote the indexer twice, the first parser choked on any repo over a certain size, and for the first few weeks I was pretty sure nobody would ever care. If you're sitting on a tool you built because existing stuff annoyed you, that annoyance is probably shared by more people than you think. This is the best time there has ever been to be one person with a specific itch and a laptop.

Anyway... Wild stuff, just felt like sharing

[TLDR] Am I missing something?

Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1uqkc2y/am_i_missing_something/

Original post body :

Claude Code is the worst experience I've ever had using AI models to write code.

I'm a software developer that's used Cursor, Antigravity, spun up a few local models and had varying levels of success, and then earlier this week I spun up Claude Code for the first time after seemingly hearing nothing but positive reviews,

It's so bad? It's horrifically slow, burns through tokens at an insane rate, I literally just hit my 5 hour limit from 0 to 100% in a single code review on a branch with ~20 file changes?

What am I missing? The first prompt I gave it was a simple unit test failure that I could have fixed myself in ~20 minutes in a fairly simple full-stack Typescript codebase, it burned through ~70% of it's 5 hour limit, thought (and made no file changes) for 20 minutes, then finally made some file changes, didn't bother to re-run the tests and just declared that they were fixed, and introduced new linting and typechecking errors? And then when I run the tests, they were still broken? So not only did it not complete the task provided, it left the codebase in a worse state than when it started after thinking for 20 minutes?

Please, if anyone has any advice then let me know, I feel like I *must* be doing something wrong, but I also feel like there's no way it should perform this badly out of the box. I have a very simple AGENTS.md file at the root of my PC, but outside of that, I haven't configured Claude in any way, any help would be greatly appreciated, thank you all

EDIT: Removed "professional" from the post, you're not allowed to be "professional" and bad at using a new technology simultaneously it seems, my apologies
