What it does
Rl K8s Sandbox Install is an agent skill from LegoX/Lego-RL. One-to-one Codex counterpart for Claude /rl:k8s-sandbox-install. Guided install or scale-out of a sandbox Kubernetes cluster for the Lego-RL k8s backend, using probes before decisions and confirmations for risky mutations. Use when the user asks to install Kubernetes, set up a cluster, add or join worker nodes, create a sandbox cluster, prepare kubeadm/containerd/flannel/ImageVolume, or asks /rl:k8s-sandbox-install.
Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in DevOps & Cloud, covering Container orchestration. It works with Kubernetes. The repository describes itself as: Lego-RL: Harness-Native Reinforcement Learning for Coding Agents. The licence is Apache-2.0.
When your agent uses it
- The user asks to install Kubernetes
- Set up a cluster
- Join worker nodes
- Create a sandbox cluster
Example prompts
- “/rl-k8s-sandbox-install”
What it can do on your machine
Read from SKILL.md and the folder at commit 0731c95. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Rl K8s Sandbox Install loads about 410 tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 147 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- rl-k8s-sandbox-install
- description
- One-to-one Codex counterpart for Claude `/rl:k8s-sandbox-install`. Guided install or scale-out of a sandbox Kubernetes cluster for the Lego-RL k8s backend, using probes before decisions and confirmations for risky mutations. Use when the user asks to install Kubernetes, set up a cluster, add or join worker nodes, create a sandbox cluster, prepare kubeadm/containerd/flannel/ImageVolume, or asks `/rl:k8s-sandbox-install`.
RL K8s Sandbox Install
Use this skill as the Codex entrypoint corresponding to Claude
/rl:k8s-sandbox-install.
Before taking task actions, read the canonical workflow in
.claude/plugins/rl-plugin/skills/k8s-sandbox-install/SKILL.md completely and
follow it as the source of truth.
Invocation Mapping
- Claude:
/rl:k8s-sandbox-install - Codex:
$rl-k8s-sandbox-installor natural language such as "install kubernetes", "set up a cluster", "add a worker node", "join worker", "new cluster", or "sandbox cluster deployment".
Codex Notes
Find the Lego-RL repo root first. It must contain
scripts/lib/site.example.env, the training runners, and the .claude plugin
path above.
Probe before deciding. Ask only for information that cannot be discovered
safely, usually how to reach the target nodes over SSH. Any kubeadm reset,
edit to an existing /etc/kubernetes, package install, service mutation, or
operation touching a cluster someone else may be using requires explicit user
confirmation and, where needed, sandbox escalation approval.
Generate a new scripts/lib/site.<name>.env rather than overwriting the default
site.env.
