+# brikie Sandbox
+
+OpenShell sandbox image pre-configured with
+[brikie](https://github.com/VeelaCleave/brikie) — a modular agent
+harness where every capability is an optional, hot-swappable Brick.
+
+## What's Included
+
+- **brikie** (from PyPI)
+- Everything from the [base sandbox](../base/README.md)
+
+## Build
+
+```bash
+docker build -t openshell-brikie .
+```
+
+To build against a specific base image:
+
+```bash
+docker build -t openshell-brikie --build-arg BASE_IMAGE=ghcr.io/nvidia/openshell-community/sandboxes/base:latest .
+```
+
+## Usage
+
+### Create a sandbox
+
+```bash
+openshell sandbox create --from brikie
+```
+
+### Pick your provider
+
+brikie reads provider credentials from the environment, so OpenShell's
+managed inference works out of the box. Choose a provider preset at
+launch:
+
+```bash
+openshell sandbox create --from brikie -- --preset anthropic   # ANTHROPIC_API_KEY
+openshell sandbox create --from brikie -- --preset openai      # OPENAI_API_KEY
+openshell sandbox create --from brikie -- --preset openrouter  # OPENROUTER_API_KEY
+openshell sandbox create --from brikie -- --preset groq        # GROQ_API_KEY
+```
+
+brikie also honors `ANTHROPIC_BASE_URL` / `OPENAI_BASE_URL`, so
+`openshell inference set` rerouting applies with no extra configuration.
+
+### Choose your bricks
+
+By default brikie boots a full stack (file tools, memory, logging,
+security, and the AFK orchestration souls). To run a leaner set:
+
+```bash
+openshell sandbox create --from brikie -- --set minimal --preset anthropic
+```
+
+Compose a custom Build Set at [brikie.co](https://brikie.co).
+
+## Network Policy
+
+The bundled `policy.yaml` allows brikie to reach:
+
+- model provider APIs (Anthropic, OpenAI, OpenRouter, Groq, DeepSeek,
+  Mistral, Cerebras, xAI, Together, Fireworks, Hugging Face, Vercel AI
+  Gateway, Google, and NVIDIA-hosted inference)
+- the brikie.co brick registry (search / install / publish)
+- the GitHub REST API, read-only (the optional issue-reading brick)
+- PyPI (installing additional bricks at runtime)
+
+Everything else is denied by default.
