  "account": "AI-powered vulnerability detection service, Chainguard Harness, debuted at the Assemble London conference today. The service utilizes Anthropic PBC's Claude Mythos 5.1 model alongside two products designed to secure AI coding agents. Additionally, Chainguard Libraries expanded to support five programming languages, including Java, Python, JavaScript, Go, and .NET. Harness reports flaws only after successfully reproducing them in a live customer application build. Developers benefit from a hardened, credential-free cloud environment provided by Chainguard Workspaces, which undergo continuous integration tests through Chainguard Checks before any pull request is opened. Workspaces and Checks cater to teams with long migrations and high permissions, ensuring secure execution without exposing real credentials. The service is currently in beta, with Workspaces and Checks available, and Harness awaiting a waitlist for its own testing.",
