Calls cmake

What it does

Cpp Best Practices is an agent skill from 2SSK/dot-files. C++ development best practices. Modern C++20/23, RAII, zero-overhead abstractions, safety. Use when writing C++ code.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: opencode

It works with C++. The licence is MIT.

When your agent uses it

Writing C++ code

Example prompts

“/cpp-best-practices”

Requirements

Compatibility (from SKILL.md): opencode

What it can do on your machine

Read from SKILL.md and the folder at commit 5cab3b1. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- cmake
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
opencode
From compatibility in the SKILL.md frontmatter.

Context cost

Cpp Best Practices loads about 489 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 64 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~34
When it runs · the whole SKILL.md, loaded when a task matches: ~489

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

C++ Best Practices

Modern C++20/23 with zero-overhead abstractions and safety.

Core Principles

RAII: Resource Acquisition Is Initialization — always
Zero-cost: Don't pay for what you don't use
Safety: Memory safety without garbage collection
Modern: Use C++20/23 features

Memory Management

cpp

// Smart pointers — always
auto ptr = std::make_unique<Resource>();
auto shared = std::make_shared<Cache>();

// No raw new/delete
// std::vector for dynamic arrays
// std::string for strings

Modern C++ Features

cpp

// Concepts (C++20)
template<typename T>
concept Hashable = requires(T a) {
    { std::hash<T>{}(a) } -> std::convertible_to<std::size_t>;
};

// Ranges (C++20)
auto results = range | std::views::filter(pred)
                   | std::views::transform(func)
                   | std::views::take(10);

// std::expected (C++23)
std::expected<int, Error> divide(int a, int b) {
    if (b == 0) return std::unexpected{DivisionByZero{}};
    return a / b;
}

Concurrency

cpp

// std::jthread for cancellation
std::jthread worker([](stop_token) {
    while (!stop_token.stop_requested()) {
        // work
    }
});

Error Handling

cpp

// Exceptions for exceptional cases
// noexcept for functions that shouldn't throw
// std::expected for fallible operations

Build Commands

bash

cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j$(nproc)
