programming-cpp — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited programming-cpp (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Modern C++ is a value-semantic language with optional escape hatches. The maintainable subset is small: RAII for resources, values by default, references for non-owning views, smart pointers when ownership is dynamic, and std:: containers/algorithms over hand-rolled equivalents. Most C++ misery comes from importing patterns from C (manual new/delete), Java (everything heap-allocated and polymorphic), or pre-C++11 codebases.
