Security plugins

Claude Code and Codex plugins their authors filed under "security". All categories.

agents-shipgate

claudecodex

Review PR changes to declared coding-agent permissions, MCP bindings, hooks and workflow permissions with the agents-shipgate diff CLI command (not routed by the plugin's skill, which covers check, verify and audit --host). This static host comparison needs no manifest, policy, saved baseline or skill; it names coverage limits and implies no verdict. Tool-Use Readiness release verification is a separate workflow for repositories with a declared tool surface. Requires the agents-shipgate CLI (pipx install agents-shipgate); no hook is enabled by this metadata.
