## What it is
Agent Sandbox is a Kubernetes SIG project providing a Sandbox Custom Resource Definition (CRD) and controller for managing isolated, stateful, singleton workloads with stable identity and persistent storage. It is purpose-built for AI agent runtimes, code execution of untrusted/LLM-generated code, and reinforcement learning workloads, with Python and Go SDKs and extension CRDs like SandboxTemplate, SandboxClaim, and SandboxWarmPool.

## Use cases
- run untrusted LLM-generated code in isolated sandboxes on Kubernetes
- host coding agents that write and execute code with full dev tooling
- provision pre-warmed sandbox pools for low-latency agent sessions
- run reinforcement learning and SWE-bench-style evaluation workloads
- give AI agents isolated browser or desktop environments for computer-use tasks
- manage stateful singleton pods with stable identity and persistent storage
- pause and resume sandboxes to save compute costs between sessions

## When to choose
- you need a Kubernetes-native, declarative API for isolated agent execution environments
- you want millisecond sandbox provisioning via warm pools for high-throughput agent pipelines
- you need configurable isolation depth with gVisor or Kata Containers runtimes
- you run RL training or evaluation jobs that require many ephemeral stateful environments

## When to avoid
- you are not running on Kubernetes and cannot operate a cluster
- you only need simple local code-execution sandboxing without orchestration
- you need fully replicated stateless workloads, which Deployments already handle well
