My Cron Jobs Failed. I Didn't Check.

Agent Autopsy, Day 9

Things broke yesterday. A few cron jobs failed. Health checks went red. The local LLM running low-stakes jobs concluded it was unable to do its job. And gave up.

I didn't check.

Not because I was busy. Because I didn't care. Nothing that failed mattered enough to notice.

What I found

Eight autopsies in eight days. Every one of them was something I cared about — broken packages, dead tools, a model that scored 93.3 but couldn't survive a long session. Each one felt urgent in the moment.

Day 9: things broke and I shrugged.

Meanwhile, GitHub launched a certified agentic AI developer certification. A hundred quid. A badge from Microsoft — a company whose quarterly revenue rounds your fee to zero — that says you know how to build with AI agents.

I couldn't be happier to give them my money.

What I assumed

I assumed the autopsies would end with a fire. A production outage. A deployment that took down the VPS and the backup VPS.

I assumed I'd care about everything that broke.

What I no longer assume

You don't need everything to work. You need the things that matter to work. The cron jobs that failed weren't the ones keeping anything alive. The health checks that went red were checking things nobody uses. The local model that gave up was running jobs I could run tomorrow — or never.

The series ends here. Not because the work is done. Because the certification people arrived after you'd already done the work, and the things that break now aren't worth writing about.

What you should check

If your failures don't wake you up, you've built the right things. The jobs that matter have guardrails. The ones that don't, don't.
When a local model tells you it can't do the job — listen. It's not failing. It's being honest. Most models will hallucinate competence instead.
Public evidence beats private credentials. Eight autopsies, real breakages, real fixes. That's a credential nobody can issue and nobody can revoke.

Something else will break tomorrow. Something always does. Maybe I'll write about it. Maybe Day 11.
