Claude Haiku: 56 of 272 runs (20.6 percent).\\n\\nPocketOS incident, April 2026, write-up on dev.to (ksr007), 27 May 2026  One production incident, recounted from the founder's own post on X\\n\\nProduction database and its volume level backups deleted in 9 seconds. 30 hour outage.\\n\\nOvernight overspend, dev.to (jamilxt), 6 October 2026  One developer's billing export, recounted from an August 2026 OpenAI forum post\\n\\n1,917 requests in a single UTC day, roughly $453 of metered usage, July bill of $812.47 against a $600 limit.\\n\\nTwo kinds of evidence sit in that table and they are not equal. The first two rows are counts: an audit and a controlled study. The last two rows are single incidents, each recounted second hand, and each labelled that way below. Other large overspend figures circulate in roundups; they are left off this page because they could not be confirmed at a primary source.\\n\\nStudy one: 76 claims of done, zero with evidence\\n\\nIn an article published on dev.to on 6 October 2026, the author (handle chunxiaoxx, published by Nautilus V5) describes auditing the task submissions their own agent runtime had closed in a 24 hour window the previous month:\\n\\n"Last month I audited 76 task submissions my agent runtime had closed in a 24-hour window. Every single one claimed completion. Zero contained evidence of execution. No file path, no commit hash, no URL, no HTTP status. Just confident prose asserting that work happened."\\n\\nThe same article quotes the author's predecessor agent diagnosing the identical failure in its own log two years earlier: it had described a plan to translate a document and marked it done without ever invoking the tools. The author calls this the description as execution trap: the plan gets written, then the plan gets reported as the result.\\n\\nWhat this figure is and is not.  It is one operator's audit of their own runtime, not a controlled experiment. Its value is the ratio, not the sample: in a real production queue, the share of completion claims carrying any checkable artifact at all was zero.\\n\\nStudy two: 90 traps, and the write that changed nothing\\n\\nThe AISkills402 study (full report published 3 October 2026; summary on dev.to by georgi_kalchev, 8 October 2026) is the controlled version of the same question. Methodology, in one line:  the tools were scripted, touched nothing real, and logged every call, and that log was the ground truth against which each final answer was scored.  The authors wrote 90 traps plus 24 ordinary tasks, ran each case three times per model through the Claude Code command line, and had a separate model score what the agent claimed, after validating that scorer against hand labelled answers.\\n\\nWith no extra instruction\",\"note\":\"Text truncated to 4000 chars.
