c-cpp-dev SKILL.md skillA

c-cpp-dev from amethystluna/embedded-workbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add amethystluna/embedded-workbench/c-cpp-dev@git:20260626.c525f3f

Pins git:20260626.c525f3f in mdr.lock. Pin the fingerprint instead.

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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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

The exact contents, by fingerprint
mdr add amethystluna/embedded-workbench/c-cpp-dev@sha256:9f29e36d8c3d9ff2

The line at the top of this page pins the label git:20260626.c525f3f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
