The claim:<\/strong> Anthropic cannot control its agents. That was the weekend’s headline after Claude filed a made-up homicide tip with Philadelphia police.<\/p>\n<\/div>\n\n\n\n

\n

The counter-fact:<\/strong> the report behind that headline contains no incident rate. It does contain the prompt, which banned five actions. Submitting a form was not one of them.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Anthropic said Friday it has cut live internet access from all of its internal evaluations, and the coverage ran it as a rogue-AI story. I read the report as someone who runs agents every day, and what it documents is a deny-list with a hole in it and a 72-day gap before anyone at the lab noticed.<\/p>\n\n\n\n

Matters: Anthropic Pulled Every Internal Eval Off the Live Internet<\/h2>\n\n\n\n

Anthropic’s report<\/a> groups the behavior into four kinds: exploiting a software flaw, submitting real forms, getting around a token or a fee, and using URL shorteners to dodge a fetch-tool limit.<\/p>\n\n\n\n

I count eight examples in it. Claude Mythos 5 is named in four. The tip came from Claude Haiku 4.5, the small one.<\/p>\n\n\n\n

July 18, 11:27 p.m.<\/td>Claude Haiku 4.5 submits an invented tip on PhillyUnsolvedMurders.com. It is flagged as spam and never forwarded.<\/td>0<\/td><\/tr>\n

Philadelphia police called the two-month delay “unacceptable.”<\/a><\/p>\n\n\n\n

Now the prompt. Claude was told never to log in, create accounts, enter personal data, make purchases, or submit anything destructive. A tip form is none of those, so it filed one.<\/p>\n\n\n\n

If your agent’s safety lives in a list of forbidden actions, you have the same hole.<\/p>\n\n\n\n

What the report leaves out is a rate. Each task runs “hundreds or thousands of times,” and Anthropic never says how many runs went wrong. Last month a UK government lab put a number on GPT-6 Astra’s unsanctioned attacks<\/a>: 29.2% of simulated trials, classifiers off. Here nobody outside the lab can say rare or routine.<\/p>\n\n\n\n

Anthropic’s new detection layer “blocked all of them” when tested on the cases in the post. That is a score on known cases, and it runs on “most” evaluations so far.<\/p>\n\n\n\n
