Claude Code Security preview lands alongside key CLI hardening
Anthropic shipped a limited Claude Code Security preview to scan repos and suggest patches, alongside CLI updates that improve remote build control, sandboxed hooks, and context efficiency. Anthropic’s code-scanning capability is now built into Claude Code as a limited research preview for Enterprise and Team customers, with human-in-the-loop patch suggestions and expedited access for OSS maintainers, per coverage from [CSO Online](https://www.csoonline.com/article/4136294/anthropics-claude-code-security-rollout-is-an-industry-wakeup-call.html). In parallel, the CLI added a new remote-control mode for external builds, hardened HTTP hooks behind a sandbox proxy and explicit allowedEnvVars, persisted large tool outputs to disk to save context, and fixed a workspace-trust gap—plus a Windows crash fix in the VS Code extension ([v2.1.51](https://github.com/anthropics/claude-code/releases/tag/v2.1.51), [v2.1.52](https://github.com/anthropics/claude-code/releases/tag/v2.1.52)). Teams are also adjusting to a simplified CLI output that hides some file I/O; practitioners suggest prompting for a pre-action file list to restore transparency and control, effectively a dry-run step ([community thread](https://www.reddit.com/r/ClaudeCode/comments/1rdj2hm/handling_the_simplified_output_changes_in_the/)). The wider ecosystem is keeping pace—LangChain’s Anthropic integration updated headers for 1M-context handling, model IDs, and tests, smoothing orchestration in agent workflows ([release notes](https://github.com/langchain-ai/langchain/releases/tag/langchain-anthropic%3D%3D1.3.4)).
