At a glance
One-to-one Codex counterpart for Claude /rl:check. An agent skill from LegoX/Lego-RL.
- The user asks to check
- SKILL.md covers Invocation Mapping and Codex Notes
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Review launch readiness
What it does
Rl Check is an agent skill from LegoX/Lego-RL. One-to-one Codex counterpart for Claude /rl:check. Preflight a Lego-RL train, eval, or infer config and answer whether it is safe to launch right now. Use when the user asks to check, preflight, validate, review launch readiness, list resolved run parameters, or asks /rl:check config.
Its SKILL.md is about 340 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 Product & Project Management, covering Feature launches and release readiness. 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 check
- Review launch readiness
- List resolved run parameters
- Asks /rl:check config
Example prompts
- “/rl-check”
What it can do on your machine
Read from SKILL.md and the folder at commit 7c30234. 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 Check loads about 338 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 140 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.

- description
- One-to-one Codex counterpart for Claude `/rl:check`. Preflight a Lego-RL train, eval, or infer config and answer whether it is safe to launch right now. Use when the user asks to check, preflight, validate, review launch readiness, list resolved run parameters, or asks `/rl:check config`.
RL Check
Use this skill as the Codex entrypoint corresponding to Claude /rl:check.
Before taking task actions, read the canonical workflow in
.claude/plugins/rl-plugin/skills/check/SKILL.md completely and follow it as
the source of truth. Treat this file as a thin adapter for Codex skill
discovery, not a replacement for the detailed rules there.
Invocation Mapping
- Claude:
/rl:check config - Codex:
$rl-checkor natural language such as "check this config", "preflight this run", "can I launch this run", or "validate the config".
Codex Notes
Find the Lego-RL repo root first. It must contain
scripts/lib/preflight.sh, scripts/lib/live_probe.sh, and the .claude
plugin path above.
Follow the Claude skill's layering rule:
- scripts own deterministic behavior
- this skill owns orchestration, live-host judgement, and the final report
Remain read-only. Do not edit configs, launch workloads, kill processes, clear shared memory, delete logs, SSH to other nodes, or mutate cluster state.
