Anthropic publishes official Claude Code repos for skills, PR automation, and security review

Anthropic has released several official GitHub repositories for building with Claude Code: skills, claude-code-action, claude-code-security-review, claude-agent-sdk-python, and claude-cookbooks, according to an X post reported by the search.

The post says claude-code-action responds to @claude mentions in pull requests and issues, writes fixes on a new branch, and signs its commits. It says claude-code-security-review scans every pull request diff for vulnerabilities and filters out noisy findings. The report is a single social media post, and the repositories are not independently verified here.
