Background & analysis
On October 8, Anthropic announced a free service called OSS Scanner that runs periodic security scans on registered open-source projects. According to Anthropic's own announcement, the resulting reports are model-generated and sent without human review.
The service uses Anthropic's most capable model to produce the reports. When a vulnerability is found, maintainers receive an email containing the finding along with reproduction steps and a suggested patch that they can apply. Scans are carried out by building the project inside an isolated virtual machine with no network access. The report also notes that maintainers may want to keep an eye on the handful of files the scanner reads during a scan.
On October 19, a further Claude-related development from Anthropic appeared, but the available material stops at that point and does not describe what it involved. Beyond the October 8 launch and the October 19 mention, the sources do not say where the service currently stands.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
