Package Claude Code as an OCI image using mise and deploy it as a kubernetes-sigs/agent-sandbox SandboxTemplate workload. Use when building a mise-driven Dockerfile for Claude Code, configuring the ~/.claude named volume for session persistence, injecting ANTHROPIC_API_KEY per SandboxClaim, applying per-pod egress allowlists for api.anthropic.com, or running Claude Code headlessly inside a Kata or gVisor isolated pod.

From the source SKILL.md

Claude Code does not ship an officially maintained standalone OCI image. The supported path is the @anthropic-ai/claude-code npm CLI plus the Anthropic-published Dev Container Feature (ghcr.io/anthropics/devcontainer-features/claude-code:1.0). For sandboxed Kubernetes deployment, the pattern is: build a Dockerfile that installs Claude Code via mise (using the registry short name), wire it into a SandboxTemplate that pins a runtimeClassName, and let agent-sandbox provision per-session pods from that template.

What this skill does
