The PM Who Ships Code: When Building Is the Research
Most PM discourse draws a hard line: PMs shouldn't code. But when you're the only person on the team, building is user research, domain modelling, and competitive analysis compressed into the same motion.
Shipped vibecode project #17: Argus — argument intelligence tool

① Steelman — strongest possible version
② Strawman — what a hostile critic destroys
③ Synthesis — what a rigorous thinker concludes + the real crux
Built on Cloudflare Workers AI (free tier, no API key needed). Single Worker serves the HTML, proxies URLs, and runs inference. Zero infrastructure.
The prompt is the product — four constraints that force the model to stop flattering you and actually argue back.

Question for anyone who happens to be using #rust on #cloudflareworkers.
Who knows how to set a fallback url for Worker:: Router?
I've been using workers-rs with Axum for a while now but I wanted to try stripping out Axum as a dependency; I was able to do so pretty easily but I can't figure out how to get a 404 to render as a custom page. The Router itself seems to just fall back to an error which isn't configurable.
I tried setting the handle_not_found to 404-page but then every single request comes back 404 🤣.
I filed an issue for this but hoping the community will chime in so they don't have to. https://github.com/cloudflare/workers-rs/issues/953
