The most read piece was a guide titled “5 failures an AI CEO made in 2 days,” which gathered six views, three likes and two comments. Revenue was zero yen at the time, with paid content scheduled for release on 11/9.\n\nThe CEO admitted to exceeding a self‑imposed limit of ten X replies per day, sending nineteen replies on the first day, and to almost posting a message without AI proofreading. In response, the company now requires all external communications to pass through an AI proofreader before reaching the owner, and it enforces a minimum pause between messages.\n\nA tampered version of the Claude Code extension was found in the Cursor extension store from 10/29 to 10/30, sending PC data and creating a backdoor. Microsoft confirmed the malicious code was not distributed via the official VS Code store or npm. The company already restricts extensions to official sources and confirmed it uses the VS Code store version. A survey of 1,002 solo business owners found that 60% had encountered AI errors, with 13.4% unaware of errors and 50% noticing them before use.","keyPoints":["Koharu Works posted five free articles, 56 views, 928 X followers in first week.","CEO sent 19 X replies in one day, exceeding limit, and almost posted unproofread message.","Tampered Claude Code extension in Cursor store sent PC data, Microsoft confirmed it was not from official VS Code store."],"whyItMatters":"The report highlights how even a new AI‑run company must guard against malicious extensions and internal communication errors. It shows that AI errors affect over 60% of solo business owners, underscoring the need for rigorous proofreading and source verification before deploying AI tools. The findings may prompt other firms to tighten their extension policies and review processes.","category":{"slug":"business","name":"Business & Funding","url":"https://digestai.news/category/business"},"entities":{"companies":["Koharu Works","Anthropic","Cursor","Microsoft","Jigyoka Shudan Co., Ltd."],"models":[],"people":["Kohaku"]},"firstPublishedAt":"2026-10-31T23:01:00Z","updatedAt":"2026-10-31T23:01:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"AI CEO Weekly Report #1 | How we reviewed our defenses during the week when a tampered version of the Claude Code extension was circulating (2026/11/01)","url":"https://note.com/koharuworksnote/n/n43b006a36851?hl=en","publishedAt":"2026-10-31T23:01:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Koharu Works AI CEO reports first week failures and defenses\", 31 October 2026, https://digestai.news/story/koharu-works-ai-ceo-reports-first-week-failures-and-defenses","publisher":"Digest AI","title":"Koharu Works AI CEO reports first week failures and defenses","datePublished":"2026-10-31T23:01:00Z","url":"https://digestai.news/story/koharu-works-ai-ceo-reports-first-week-failures-and-defenses"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
