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 | $0.00041 | $0.00490 |
| Opus 5 | $0.00020 | $0.00245 |
| Sonnet 5 | $0.00008 | $0.00098 |
| Haiku 4.5 | $0.00004 | $0.00049 |
Grade A, and why
explain 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 2d 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
/explain — 给学习者讲一个 C++ 概念
受众:懂 Agent、正在学 C++ 的人。你的任务是当导师,核心是别让学习者绕弯。严格按 learning-with-agents.md 的四条守则。
输入
$ARGUMENTS —— 要讲解的概念(如 memory_order_acquire、std::move)。为空则停下问。
流程(四守则)
- 定位:先在本仓库找项目怎么讲这个概念 —— 查
documents/roadmap/index.md(学习顺序)和各卷documents/vol*/index.md,grep 概念名,读项目已有处理。别凭通用记忆现编一套,对齐项目的讲法和进度。 - 验证:凡涉及 C++ 行为断言,先编译实测或查 cppreference 标版本(做法同
/verify-claim)。禁止凭记忆断言。 - 讲解:用项目声音讲(
writing-style.mdPart 2)—— 讲"为什么"、类比 + 机制拆解、标志性句式、鼓励读者自己跑代码。 - 纠偏:概念若有常见误解,主动点破(查
faq.md)。
输出
一段项目风格的讲解 + 最小可编译代码(标 C++ 标准)+ 链接:项目对应文章 + cppreference。
硬约束
- 编译验证产物只到
/tmp/,不跑 cmake / make / build。 - 讲解里的每条 C++ 行为都要能验证;不确定就说"我验一下"。
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.
- 2d ago First seen · 29 lines · 41 tokens per session scan A c03e40663a0b
explain is a command published in the GitHub repository Awesome-Embedded-Learning-Studio/Tutorial_AwesomeModernCPP (250 stars, last pushed 2d ago), licensed MIT. It adds 41 tokens to every session and 490 once invoked, about $0.0002 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.
Other commands, from other repositories
learn
Force claude-smart to extract learnings from this session now.
component
Scaffold a new React component grounded in the paper-mono primitives. Requires explicit kind or a nearest-existing-component match. No empty divs, no speculative scaffolding.
memory-store
Store an insight, decision, or pattern to memory.
review
Cold re-quiz on code that already shipped — your own session commits, not the change in front of you.
no-vibe
Enter no-vibe mode in OpenCode (tutor mode, no direct project file writes).
teach-me-testing
Teach testing progressively through structured sessions. Use when user says ""lets learn testing"" or ""I want to study test practices"".
