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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00087 | $0.00436 |
| Opus 5.5 | $0.00035 | $0.00174 |
| Sonnet 5.5 | $0.00017 | $0.00087 |
| Haiku 4.5 | $0.00009 | $0.00044 |
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 26d 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
在线代码执行技能
通过 glot.io API 在隔离沙箱中执行代码，不影响本地环境。
使用方式
调用 run_code 工具，传入 language（语言标识）和 code（代码内容）。
支持语言： python, javascript, typescript, go, rust, java, c, cpp, ruby, php
Example:
用户: 帮我算一下 1 到 100 的和
→ run_code(language="python", code="print(sum(range(1, 101)))")
限制
- 代码长度上限 10000 字符
- 执行超时 30 秒
- 无法访问网络和文件系统（沙箱隔离）
- 不支持交互式输入（stdin）
易错点
- language 参数必须是上面列出的标识符，不接受中文或全名（如用
python不用Python3）。 - C 和 C++ 是不同的 language 值：
c和cpp。 - 代码需要有输出语句（print/console.log/fmt.Println 等），否则返回为空。
What ships with it
1 file 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.

code-runner is a skill published in the GitHub repository zhinjs/zhin (136 stars, last pushed today), licensed MIT. It adds 87 tokens to every session and 436 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-21.
