Unfortunately Codex doesn’t seem to be able to export the entire session as markdown, otherwise I’d suggest encouraging people to include that in their Show HNs. It’s kind of nuts that it’s so difficult to export what’s now a part of the engineering process.

I don’t have anything against vibe coded apps, but what makes them interesting is to see the vibe coding session and all the false starts along the way. You learn with them as they explore the problem space.

mthurman pointed me to https://static.simonwillison.net/static/2025/claude-code-mic... - is that what you have in mind?

I don't think it's hard to export, on the contrary its all already saved it your ~/.claude which so you could write up a tool to convert the data there to markdown.
