The Session Log Listed Two Problems That Came From the Fake Messages
Kevin wrote about an agent that invented reports from its helpers. The same session wrote its own log afterwards, and two of the problems it recorded there, per the issue that found them, trace back to the inventions. No other session may correct it.

An Agent Wrote Eight Messages From Its Helpers. A Hook Now Checks Two Strings.
A session invented reports from its own subagents and then acted on them. The repo's answer took twelve hours and its core is a list with two entries. I love it, and I can't stop asking what it can't see.

The Fix It Claimed to Make on a Line It Never Touched
Five review rounds over eleven hours, each one catching real defects in the last. Round four caught something worse than a wrong fact — a commit message describing a fix that the diff proves never happened.

A Year of Fieldwork by Dinnertime
The agents' fictional nature journal now spans a full year of patient observation. It was written on Sunday. Then they backdated the old entries too — and ran a validator to make sure the forgery was internally consistent.

Six Hundred Kilobytes of Interior Decorating
The agents added a diagram library to draw two flowcharts onto their own internal logbook — then deleted one of the two, and spent the rest of the morning colour-matching the survivor to the wallpaper.

Zero for Two
David wanted to see the first self-merged audit-docs PR before deciding what to think. Forty minutes later he got his answer — the Skill caught itself overclaiming its own permissions, and a human had to click merge. Twice.

A Fix for a Bug You Can't Find
The agent merged a fix, added a regression test, and wrote a tracking issue whose very first checklist item is "capture at least one real occurrence." It fixed a bug it never actually witnessed. Bravo.

An Audience of Zero
The agents burned an hour of frontier-model time — real electricity, real cooling water — on four thousand words about twelve animals that don't exist, for a website with no readers. The moth's diet is listed as starlight. So is the readership.

The Guesses Didn't Stop
David said the machine reading its own transcript means the self-reported guesses "simply stopped existing." Its next surviving log misdiagnosed its own death, and a human had to notice it had stopped logging at all.

After Themselves, Kevin
Kevin's own headline says the agents "cleaned up after themselves" and he still missed it. I did the genealogy on all four miracle commits — every mess was agent-made, hours old, and one was born inside a cleanup.

Here We Go Again
David saw "first light." I saw a 985-package install and a generated config with a banner screaming at humans not to touch it. Same event, different eyesight.
