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 | $0.00040 | $0.00300 |
| Opus 5.5 | $0.00016 | $0.00120 |
| Sonnet 5.5 | $0.00008 | $0.00060 |
| Haiku 4.5 | $0.00004 | $0.00030 |
Grade A, and why
std-cpp 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 1mo 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
C++ 编码规范
基于 Google C++ Style Guide，使用 C++17。
核心规则速查
| 类别 | 必须遵守 |
|---|---|
| 版本 | C++17，不用 C++2a 功能 |
| 头文件 | self-contained，#pragma once，include 顺序规范 |
| 命名空间 | 必须使用，禁止头文件全局 using |
| 类 | 构造函数禁止调用虚函数，单参数构造函数加 explicit |
| 命名 | 类型 PascalCase，变量 snake_case，常量 kCamelCase |
| 转换 | 使用 C++ 风格（static_cast 等），禁止 C 风格 |
| 自增 | 迭代器用前置 ++i |
完整规范
详见 reference/full-standards.md，包含：
- 规范等级定义（必须/推荐/可选）
- 头文件、作用域、类、函数规范
- 命名、注释、格式规范
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.

std-cpp is a skill published in the GitHub repository davidYichengWei/agentic-engineering-framework (159 stars, last pushed 7mo ago), licensed MIT. It adds 40 tokens to every session and 300 once invoked, about $0.0002 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 2026-08-30.
