About this plugin
Claude Security runs vulnerability scans inside your Claude Code session, using your selected scope and effort tier. It can inspect a whole repository, a branch or pull request diff, or a single commit, then challenges findings with independent verification before adding them to the report.
When you choose to fix an issue, the plugin turns confirmed findings into targeted patch files. Each patch is checked by a panel of agents, and you decide whether to review and apply it. Scans and fixes run under your session's permissions, so use a sandbox for repositories you do not trust.
