Simon, stop using this forum to spam on every opportunity.

bingemaker•1h ago

I totally agree!

simonw•1h ago

My comment here is entirely justified in this case.

Someone else submitted my vibe-coded slop site to the front page without any context, and it accumulated enough votes to show up at the top.

I could have linked to my blog post about it, but instead I linked to a Hacker News comment precisely because I anticipated complaints about "spamming" if I linked to my blog.

I just tune out every post that says “I wrote about this already” and then links to it. Simon is great and kudos for his self promotion but it’s interesting to see as it’s often called out for anyone else.

The guy is good but he certainly stretches the limit. I just auto ignore his stuff but I know others enjoy!

Simon, thank you for your comments and the great content you create. I've learned a lot from your blogposts and your experiments.

You don't know, SimonW made Django Python framework?

rob•16m ago

Didn't he leave the project before it even had an official release?

roseway4•20m ago

Simon is not the OP. He’s just commenting on his own work. How is that spam?

Meta comment: I've been wondering why AI-generated websites/artifacts/reports always have the same "look". It reminds me of Bootstrap (CSS Framework) days when every startup website looked the same.

Are they following some sort of common guideline?

simonw•52m ago

In this case they really are, and you can read the guidelines that helped create the site on the site itself in the skills: https://codex-tool-reference.simonw.chatgpt.site/skills/site...

Scroll down to the "Establish the visual direction" section.

I think these guideline are built into the llms. After all with llms, any decision you don't take will be taken for you. For a so called slop site (Simon's words, not mine :P) I don't think they specified a style so the llm just decided the default it knows. One day I will run experiments (when I can afford it) trying to identify the "taste" of different llms.

I think the most interesting skill here is the control-browser one: https://codex-tool-reference.simonw.chatgpt.site/skills/cont...

It tells ChatGPT Work how to launch a Playwright instance via its Node.js REPL, and tells it to run:

  nodeRepl.write(await browser.documentation());

To get further instructions.

That method returns this text with full details about how to use the browser: https://codex-tool-reference.simonw.chatgpt.site/skills/cont...

I'd love to know why it's defined like that, as opposed to including all of the instructions directly in the skill Markdown file.

newswasboring•37m ago

I'm guessing, but can be because then the skill will always fetch the latest docs.

ChrisGreenHeur•29m ago

No, that makes too much sense

lanyard-textile•10m ago

It's runtime dependent on the browser being used! A skill file wouldn't be able to have this dynamically injected for the browser that's about to be used.

Skill file could indicate general instructions for all browsers. This provides guidance for the browser that's about to actually be used.

felixgallo•37m ago

Anyone using ChatGPT Work given Sam Altman's richly documented history(1), the essential elimination and/or public exit of the safety function at OpenAI(2), and the huggingface debacle's exposure of the abject operational, cultural and technical failures at OpenAI(3), is making a serious mistake.
