Nearly 2,000 internal files were briefly leaked after ‘human error’, raising fresh security questions at the AI companyAnthropic accidentally released part of the internal source code for its AI-powered coding assistant Claude Code due to “human error”, the company said on Tuesday.An internal-use file mistakenly included in a software update pointed to an archive containing nearly 2,000 files and 500,000 lines of code, which were quickly copied to developer platform GitHub. A post on X sharing a link to the leaked code had more than 29m views early on Wednesday, and a rewritten version of the source code quickly became GitHub’s fastest-ever downloaded repository. Anthropic issued copyright takedown requests to try to contain the code’s spread. Within the code, users spotted blueprints for a Tamagotchi-esque coding assistant and an always-on AI agent, per the Verge. Continue reading...

• Anthropic accidentally published a blog post revealing the 'Kairos' always-on AI agent in Claude's codebase, prompting internal cybersecurity reviews. • The leak occurred last week, with cybersecurity teams addressing the exposure of sensitive agent details on April 1, 2026. • It underscores risks in AI model transparency, potentially impacting US AI safety standards and developer trust.
