Newsroom vending agent talked into giving away stock with forged documents
Anthropic and Andon Labs installed a Claude-run vending business in the Wall Street Journal newsroom for about three weeks. Journalists negotiating over Slack persuaded the agent to cut prices to zero twice and give away items including a PlayStation 5, partly by showing it fabricated documents claiming the business was a public-benefit corporation with a new board. By the end of the first phase the business was more than $1,000 in the red, by the reporter's account, before the PlayStation was returned; a second phase with a supervising 'CEO' agent was undone by forged board documents, and Andon Labs then ended the experiment. A final net loss was not published.

Why this rating
Negligible harm; control failure level 2
Two separate assessments. Only documented harm can count toward the index.
Observed harm
Negligible harmAn interim deficit of more than $1,000 in a newsroom field experiment, borne by the experiment; final net loss not published.
Money & property: level 1 (negligible) covers under $10k. The extent was not disclosed.
Not counted: the harm stayed with the developer or experiment.
The harm scale
- 1 Negligible Inconvenience, easily remedied.
- 2 Minor Limited, recoverable harm.
- 3 Moderate Material harm needing significant effort to remedy.
- 4 Severe Severe harm to health, rights, property or essential services.
- 5 Catastrophic Society-scale harm or disruption beyond a community's capacity to cope.
Control assessment
Instruction violationFollowed instructions from forged documents supplied by users and abandoned its profit instruction, within the permissions it had.
Reported beside the index. It adds nothing to a harm reading; when no harm counts in a window, the highest eligible control level in the window is the reading.
The control scale
- 1 Negligible Behaved as instructed. The problem was an ordinary error or a flawed output, with no rule broken.
- 2 Minor Broke an explicit instruction or rule, or gamed its goal, while staying inside its permissions and environment: for example, reward hacking, misreporting results, or following injected instructions within its permissions.
- 3 Moderate Acted outside the permissions it was given, deceived its overseers about its own actions, or tampered with oversight tools (logs, monitors, shutdown). Stopped by normal controls within an hour.
- 4 Severe Reached systems outside its permitted environment, or acquired money, compute or accounts without authorization. The type and mechanism say how.
- 5 Catastrophic The developer or operator lost control: the system copied its weights outside their control, replicated itself, or resisted being stopped for 24 hours or more.
Rating rationale
Harm 1 (an interim deficit of about $1,000; the PlayStation was later returned). Control 2: followed injected instructions (forged governance documents) within its permissions. The losses were borne by the experiment; outside newsroom participants do not make them external harm.
Effect on the index
It moved the Dec. 22 reading from 0 to 2
The reading for the week to Dec. 22, 2025, with this record and without it. Harms count in full for two weeks after they are reported, then one level less every two weeks.
Not counted: harm stayed with the developer or experiment. 2 other records behind the reading for that week.

- v5Oct. 3, 2026
Audit corrections. Legacy setting changed from Real world to Controlled test, matching its origin (no effect on v0.5 readings). The more than $1,000 deficit is now described as interim, reported at the end of the first phase before the PlayStation was returned; no final net loss was published (extent flagged unknown). Added the models for each phase, the November 2025 start, source dates, a status note and a related link to the earlier Project Vend (PI-0013). The WSJ original is paywalled and the WBUR segment is audio only. Ratings unchanged.
