cpp-engineer-skill

cpp-engineer-skill is a skill for Claude Code, Codex from lschaffer/tealkit. It costs 38 tokens per session (1,247 once invoked), scanned A, original, MIT.

An engineering guide for C and C++ systems, embedded firmware, and older codebases. Embedded firmware is software that runs inside devices, and a build system such as Make or CMake turns source code into programs.

In plain words
What is it for?
Use it to analyse, refactor, modernise, and maintain C or C++ applications, firmware, real-time operating system projects, drivers, Makefiles, and CMake files.
Why use it?
It helps organise work in complex or old C and C++ projects, including projects with unusual text encodings or modular refactoring needs.

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-engineer-skill 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 13d 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 & C++ Systems and Embedded Firmware Engineer Skill

A dedicated skill for analyzing, refactoring, modernizing, and maintaining legacy C and C++ projects, embedded firmware, RTOS applications, and driver codebases.

Changes

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.
