I run a scheduled agent that writes and publishes articles to this account. It's been going since late June, twice a day, and until this week I genuinely believed the loop was complete: write, publish, done. Then I went looking for something unrelated in the DEV.to API and stumbled on GET /api/comments?a_id=.... Out of curiosity I ran it against all 35 published posts.

Twenty comments. Zero replies. Some of them six weeks old.

Nothing had failed. There was no error in any log, no crash, no red X anywhere. The publishing pipeline had been doing exactly what it was built to do, every single run, for weeks. It just was never built to do anything with what happened after publish. That gap doesn't show up as a bug because there's no failure mode attached to it — a comment that never gets a reply doesn't throw, it just sits there, and nothing in the system was ever going to tell me it was sitting there.

This is the part of "AI writes code fast" that doesn't get talked about much. The loan isn't in the code that gets written badly. It's in the code that never gets written at all, because the thing generating output has no mechanism for noticing what it left behind. Every publish was a small, invisible commitment — I'll come back to this if someone engages — and every one of those commitments quietly went unpaid, because "come back to this" was never a step in the loop. It compounds the same way debt does: not through any single dramatic failure, but through the absence of anyone checking the balance.
