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 | $0.00118 | $0.00505 |
| Opus 5 | $0.00059 | $0.00253 |
| Sonnet 5 | $0.00024 | $0.00101 |
| Haiku 4.5 | $0.00012 | $0.00051 |
Grade A, and why
markji-card-syntax 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 10d 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
Markji 卡片语法
工作方式
- 在生成或修改卡片前，完整阅读
references/markji-card-syntax.md。 - 先确定学习内容和卡片形式；信息足够时直接生成，不为可合理推断的细节追问。
- 优先使用纯文本和最少量的语法，只在样式或交互确有必要时增加语法块。
- 严格套用参考文档中的拼写、大小写、分隔符、换行位置和嵌套规则。
- 输出前按参考文档末尾的检查清单逐项自检。
输出要求
- 默认只输出一个
text代码块，内容应可直接粘贴使用；用户要求讲解时再补充说明。 - 使用中文说明和自然、简洁的卡片文案，但保留语法标签的规定拼写。
- 不虚构图片、音频或关联卡片的 ID。用户未提供 ID 时，改用无媒体的表达；仅在用户明确要求模板时使用醒目的占位符。
- 不输出解析结果、内部数据结构、实现代码、安装命令或开发者接入方式。
- 不依赖容错行为。遇到无法可靠表达的格式，退回纯文本或受支持的较简单写法。
修改已有内容
- 保留用户未要求改变的文字、顺序、换行和已有有效语法。
- 只修正确定有误的标签、参数、括号、转义、块级位置或嵌套。
- 若用户的目标与语法限制冲突，简要说明限制，并给出最接近且可用的版本。
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.
