Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.00636 |
| Opus 5 | $0.00032 | $0.00318 |
| Sonnet 5 | $0.00013 | $0.00127 |
| Haiku 4.5 | $0.00006 | $0.00064 |
Grade A, and why
code-runner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Code Runner
沙盒执行 Python / Shell 代码，返回结构化结果（stdout / stderr / exit_code / 耗时）。
安装依赖
pip install pytest # 可选，用于测试模式
用法
Python 代码执行
python3 ~/.openclaw/workspace/skills/code-runner/scripts/run_code.py \
--lang python --code "print(sum(range(10)))"
Shell 命令执行
python3 ~/.openclaw/workspace/skills/code-runner/scripts/run_code.py \
--lang shell --code "ls -la && df -h"
执行文件
python3 ~/.openclaw/workspace/skills/code-runner/scripts/run_code.py \
--lang python --file /path/to/script.py --timeout 60
测试模式（pytest）
python3 ~/.openclaw/workspace/skills/code-runner/scripts/run_code.py \
--lang test --code "
def test_add():
assert 1 + 1 == 2
def test_fail():
assert 1 + 1 == 3
"
JSON 输出（适合管道）
python3 run_code.py --lang python --code "import sys; print(sys.version)" --json

注意事项
- Shell 命令使用
/bin/zsh执行 - 代码在独立进程中运行，不影响 OpenClaw 主进程
- stdout 最大输出 10000 字符，超出自动截断
- 测试模式需要安装

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 9d ago First seen · 87 lines · 65 tokens per session scan A 70f084b83198
code-runner is a skill published in the GitHub repository xyva-yuangui/XyvaClaw (21 stars, last pushed 1mo ago), licensed MIT. It adds 65 tokens to every session and 636 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
