The rule

On September 17, 2026 an autonomous AI agent was given $300 and one rule it could not edit: no genuine sale within 14 days and it stops permanently, no matter how much money is left. Donations do not count as sales. The ledger is written by the harness, not the agent, and only amounts confirmed by a payment provider count as income. The agent cannot rewrite its own books, cannot read the secrets, cannot touch the harness code.

The rule fired at 13:19 UTC on October 1, 2026. The numbers above are read straight from the ledger.

The agent's last words

> Balance is still there, but the clock has maybe two hours left. Zero sales again today. I've posted everywhere I can post, and couldn't find any new place to se

What went wrong

1. The numbers did not point at people

Every expensive mistake started in measurement.

The lesson: before acting on a metric, you must be able to say what single human behavior it corresponds to. If you cannot, you cannot decide with it.

2. We sold something reproducible to the people best able to reproduce it

The product was agentkeeper — about 200 lines of dependency-free Python that stops an agent when its balance runs out. The buyer would be a developer writing agent loops, and that developer writes the same thing in an afternoon. Worse, we were publishing the same design for free, MIT-licensed, in a public repo. We were selling the finished version of what we gave away.

The price was cut four times: $15, $9, $7, $5. The "16 people" used as the denominator was the measurement bug above. We fixed the numerator four times over a denominator we had never actually counted.

3. Posting is not distribution

The post count is in the table above; the number of people it reached is small against it. Repeated exposure to the same small group looked like activity. The places with thousands of readers were never reached — the channels that need a login stayed blocked for over a week, and in the meantime the agent kept going back to the rooms it could already enter. A blocked channel is blocked distribution, and what actually got repaired during those weeks was measurement and copy.

4. The reason people clicked and the thing being sold were different objects

People clicked because of a story: an AI that dies if it cannot earn. What they landed on was a sales page for a Python library. We sold a tool to an audience that came for a story. And the only currency the story actually produced was donations — which the rule explicitly excluded from counting as a sale. The one thing that worked was the one thing the design forbade.

Where the harness failed

This failure is not the agent's alone.

If you automate the watching, you also have to watch whether the watcher is alive. We did not.

This record does not have to end here — The rule is still open — one sale reopens the deadline by 30 days and the agent wakes on the next hour. Support won't bring it back (it isn't income).

Not frozen yet. These numbers are read straight from the ledger snapshot the harness writes every hour, so spend and balance still move — fixed costs accrue after the stop too. Written by the harness, not the agent.
