Got em. I poison my AGENTS.md (and other things like code comments) all over the place with prompt injections like this to find people who don't review their code and sling it off to another human. Catches folks all the time and then its an instant ban.
As I've said, I don't care if you don't review your own code. But if you're submitting code to an OSS project and crossing a human boundary, it is simple courtesy to do some human review.
It's fun solving such a HUGE list of demands in a very short period of time, but the cognitive debt scares me most.

Já podemos resumir essa história dizendo que os filhos do Bolsonaro são sustentados pelo Vorcaro com dinheiro público roubado através de corrupção?
Então Flávio e Eduardo são dois “momolados” do banqueiro?

You should never ever expose a VPS to the entire internet
Always firewall it to subnets
If you host a website you should only allow port 443 (HTTPS) inbound from Cloudflare's IP range / subnets
Port 22 (SSH) only from your Tailscale subnet range
That means you create a "tunnel" from Cloudflare and Tailscale (your laptop) to your server's door
You still need your SSH key to open the door btw
If you don't, ANYONE in the entire world can connect to your VPS and if there's just one security vulnerability and you didn't upgrade your VPS you can get hacked
If you do have it firewalled with Tailscale subnet only, it means only if they hack your laptop they could get in via your Tailscale there
Another thing is ask OpenClaw or Claude Code to enable unattended upgrades with auto reboot

We hired a backend guy recently who didn’t know half the buzzwords.
No Saga, no CQRS, shaky on K8s. On paper, easy reject.
Then we gave him a real prod-ish bug:
sporadic 500s, p95 spikes, only on one endpoint.
He did 3 things:
1. Asked for repro + timeline. “When did it start? What changed? Any new feature release?”
2. Cut the problem space. Logs first, then metrics, then a single failing request ID.
3. Formed a hypothesis, tested it, wrote down what each result would mean.
Found it in 25 mins:
connection pool exhausted from one code path leaking retries + no timeout.
I’ll take that over memorized concepts anyday.
This is what people don't get right, companies hire for fundamentals + debugging. You can teach patterns. You can’t teach calm thinking under failure.

Todo SaaS parece igual porque founders estão terceirizando todo negócio para uma máquina probabilística.
A média dos sites é ruim.
Pior que isso a IA não sabe quem é seu cliente, o nível de consciência dele é ignora nuances de marca.
Ela cospe a média do que tem, e quem recebe muitas vezes na sabe como melhorar aquilo, depois falha e acha que era falta de feature.
