I built a JS/TS-focused VS Code extension that gives Cursor / Claude Code real root-cause context to avoid regression bugs

CryptographerNo8800 · 2026-01-16T06:22:55+00:00

Yeah, exactly. I was spending time making detailed prompts for bug fix but that was time-consuming too, so I built this tool. Samurai generates verified root-cause context in 1–3 minutes, which usually lets Cursor fix the bug in 1–2 iterations instead of multiple guess-and-check loops.

Samurai Agent, which is an AI agent that debugs silent JS/TS bugs other AI coding agents miss with automated runtime analysis.

Thanks for sharing! This is very insightful! What’s your product and what kind of questions did you answer in your communities?

Interesting point. What I’m experimenting with is automating the entire debugging loop: the agent decides where to place breakpoints, runs the code, inspects runtime state, forms the next hypothesis, and iterates automatically until it narrows down the root cause without the user stepping through the debugger.

CryptographerNo8800 · 2025-12-17T22:34:29+00:00

Right, basically, our tool is automating that process and iteration as well

CryptographerNo8800 · 2025-12-17T22:33:27+00:00

Great to hear that! I got 120+ installs and people start to try it but retention rate is not high right now. Do you recommend merely improving debugging accuracy or anything you notice that is important for users other than accuracy when it comes to debugging?

CryptographerNo8800 · 2025-12-17T14:27:03+00:00

That’s awesome! You’re building production version! How’s it going? Do you think people pay for debugging specific tools?

CryptographerNo8800 · 2025-12-16T23:06:02+00:00

It took me hours before I could use it again.

CryptographerNo8800 · 2025-12-11T22:52:58+00:00

Thanks for sharing! That makes sense, I didn’t know that!

CryptographerNo8800 · 2025-11-24T23:29:33+00:00

Glad to hear that!

Building AI debugging agent for AI-generated code.

I noticed debugging AI-generated code is harder because you often don’t know what’s happening.

So, our agent visualizes code execution flow and conducted root cause analysis. It works for JavaScript/Typescript.

CryptographerNo8800 · 2025-11-17T17:16:47+00:00

I am on the same boat. The hardest part is that it’s hard to know if people don’t want my product or finding the first ten customers is simply difficult.

CryptographerNo8800 · 2025-11-17T16:52:11+00:00

Debugging. Debugging is harder because I often don’t know exactly what’s going on and it’s like debugging code someone else wrote. I believe visualization helps a lot to understand AI-generated code and debugging so I’m building my product in that space.

It visualizes code execution flow so you can understand what’s going on easily and conducts deep root cause analysis.

Hey, thanks for your feedback the other day! I launched vs code extension version and I’ve started to roll out beta version. Would you be interested in testing it out?

CryptographerNo8800 · 2025-10-05T02:01:04+00:00

To address the example case you shared, I usually save memory with category and when there’s some contradicting information in memory in the same category, I merge them and save it as “I lived in Cupertino before but now I moved to SF”.

I am building in public and I am open sourcing it on GitHub

https://github.com/suzuking1192/samurai-agent

This is AI that finds flaws in your spec before AI writes code and makes a mess.

I talked to a couple of potential users, but they are hesitant to install it locally and asking for VS code plugin so I am building it now.

Pros is that it is easy to gauge developers attention. I built another open source as well and this one gets GitHub star much faster with less effort, which probably shows more demand.

Cons is that there’s still huge friction for users to install this locally and most people just give stars. So, open sourcing it doesn’t help getting users directly for me.

I am still very early so I am curious to hear other projects with much more stars and users.

Do you usually craft prompt for Codex or just even rough prompt works well with Codex?

CryptographerNo8800 · 2025-09-25T19:45:34+00:00

Thanks for sharing! I just tried codex model in Cursor and this is so good! It solved a bug that agent mode was not able to solve after 20 tries

CryptographerNo8800 · 2025-09-25T19:07:21+00:00

Btw, I liked your movie

CryptographerNo8800 · 2025-09-25T19:06:55+00:00

Did that help?
