+
+This lab shows you how to run AI coding agents inside isolated Docker Sandboxes
+(`sbx`) and progressively harden what the agent produces using sbx **kits** and
+**Docker Hardened Images (DHI)**. You'll start with a plain sandbox, attach a
+container best-practices kit to change how the agent writes Dockerfiles, then add
+a DHI kit so the agent builds and runs on hardened base images. Along the way
+you'll compare baseline and hardened images on size, packages, vulnerabilities,
+and attestations.
+
+## Launch the lab
+
+{{< labspace-launch image="dockersamples/labspace-sbx-kits-dhi" >}}
+
+## What you'll learn
+
+- Run an AI coding agent (Claude) in an isolated Docker Sandbox microVM with its own daemon, filesystem, and network
+- Apply sandbox network policy that allows approved development endpoints and denies everything else
+- Define an sbx kit: declarative, shareable agent configuration (tools, credentials, network rules, files, startup commands, and guidance) in a single `spec.yaml`
+- Compare the output of a plain sandbox against one guided by a container best-practices kit
+- Use a DHI kit to direct the agent to build and run on Docker Hardened Images
+- Keep registry credentials on the host with sbx custom secrets, so your Docker PAT never enters the sandbox VM
+- Push baseline vs. DHI image tags and compare size, package count, vulnerabilities, and attestations (SBOM + provenance) in Docker Hub and Docker Scout

+## Modules
+
+| # | Module | Description |
+|---|--------|-------------|
+| 0 | Prerequisites | Set up Docker Desktop, the `sbx` CLI, and a Docker Personal Access Token for pulling Docker Hardened Images |
+| 1 | Start with a Plain Sandbox | Run an AI coding agent in an isolated Docker Sandbox microVM and review its default container output |
+| 2 | Add the Best Practices Kit | Attach a container best-practices kit and compare how the agent's Dockerfile changes |
+| 3 | Add the DHI Kit | Direct the agent to use Docker Hardened Images, then compare image size, packages, vulnerabilities, and attestations |
