Reins adds deterministic PreToolUse and PostToolUse security hooks for agent runtimes. It enforces rules (allow/warn/block) for shell commands, file edits, and MCP calls, logs audit entries, and can integrate with Watchtower for centralized policies and immutable admin rules.
Use Reins whenever an agent has permission to run shell or file operations, access external MCPs, or perform potentially destructive work — especially in production, shared, or sensitive environments. It's also useful during audits or when enforcing org-wide safety policies.
Best suited for Claude Code and other agent runtimes that support pre/post tool hooks and shell interception.
