c-cpp-dev skillA

c-cpp-dev is agent-read markdown (skill) from amethystluna/embedded-workbench: Use when writing, reviewing, or refactoring C/C++ code, especially on 32-bit ARM embedded targets. NOT for formatting-only changes, simple file reads, non-embedded C/C++ (desktop/server), or C#/Java despite the 'C' in the name..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

<HARD-GATE>
This is a domain implementation skill. If you are planning, designing, or entering plan mode — load `Skill("embedded-workbench")` first to activate the workflow gates (Plan Verification Gate, Approval Gate, Closure Gate). Domain skills carry implementation guidance, not workflow enforcement.
</HARD-GATE>

# C/C++ Development

Language baseline is project-specific: check the project's CLAUDE.md, build system (`-std=` flags), or compiler configuration. All rules assume 32-bit ARM target unless otherwise noted.

## Code Generation

- Respect the project's configured language standard. Don't assume a default.
- When a header is shared between C and C++ translation units, never define variables in the header — not even with `static`. Use `extern` in the header and exactly one definition in a single `.c` file.
- Allow `goto` when it simplifies cleanup or reduces complexity, but use it as a maintenance tool, not a first choice.
- Place Doxygen comments in header files. Keep implementation files focused on behavior.
- Avoid inline functions in header files. Keep function definitions in source files so the interface stays small.

How to install

Latest version
mdr add amethystluna/embedded-workbench/c-cpp-dev@git:20260626.c525f3f
Exact content
mdr add amethystluna/embedded-workbench/c-cpp-dev@sha256:9f29e36d8c3d9ff2

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
