cpp-coding-standards

cpp-coding-standards is a skill for Claude Code, Codex from majiang213/OpenClaw-MAS. It costs 48 tokens per session (6,022 once invoked), scanned A, a copy of cpp-coding-standards, MIT.

A set of guidelines for writing modern C++ code, based on the C++ Core Guidelines. It covers practices such as safer resource handling, clearer code, and using the type system to prevent mistakes.

In plain words
What is it for?
Writing, reviewing, or refactoring C++17, C++20, or C++23 code, and deciding between alternatives such as smart pointers versus raw pointers.
Why use it?
It helps developers make consistent C++ choices and avoid common safety and maintenance problems. It is intended for modern C++, not ordinary C or projects that cannot adopt newer language features.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

cpp-coding-standards 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.

C++ Coding Standards (C++ Core Guidelines)

Comprehensive coding standards for modern C++ (C++17/20/23) derived from the C++ Core Guidelines. Enforces type safety, resource safety, immutability, and clarity.

When to Use

  • Writing new C++ code (classes, functions, templates)
  • Reviewing or refactoring existing C++ code
  • Making architectural decisions in C++ projects
  • Enforcing consistent style across a C++ codebase
  • Choosing between language features (e.g., enum vs enum class, raw pointer vs smart pointer)

When NOT to Use

  • Non-C++ projects
  • Legacy C codebases that cannot adopt modern C++ features
  • Embedded/bare-metal contexts where specific guidelines conflict with hardware constraints (adapt selectively)

Cross-Cutting Principles

These themes recur across the entire guidelines and form the foundation:

  1. RAII everywhere (P.8, R.1, E.6, CP.20): Bind resource lifetime to object lifetime
  2. Immutability by default (P.10, Con.1-5, ES.25): Start with const/constexpr; mutability is the exception
  3. Type safety (P.4, I.4, ES.46-49, Enum.3): Use the type system to prevent errors at compile time
  4. Express intent (P.3, F.1, NL.1-2, T.10): Names, types, and concepts should communicate purpose
  5. Minimize complexity (F.2-3, ES.5, Per.4-5): Simple code is correct code
  6. Value semantics over pointer semantics (C.10, R.3-5, F.20, CP.31): Prefer returning by value and scoped objects

Philosophy & Interfaces (P., I.)

Key Rules

Rule Summary
P.1 Express ideas directly in code
P.3 Express intent
P.4 Ideally, a program should be statically type safe
P.5 Prefer compile-time checking to run-time checking
P.8 Don't leak any resources
P.10 Prefer immutable data to mutable data
I.1 Make interfaces explicit
I.2 Avoid non-const global variables
I.4 Make interfaces precisely and strongly typed
I.11 Never transfer ownership by a raw pointer or reference
I.23 Keep the number of function arguments low
