Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

cpp 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 1mo 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.

"description": "Two complementary modern-C++ (C++17) native-addon skills for Claude Code. resource-review traces object and resource lifetimes and reports only proven memory/resource defects (use-after-free, double-free, leaks, out-of-bounds, integer overflow, data races, Node-API handle/reference/threadsafe-function misuse), using a sanitizer stack trace as proof. project-setup assesses cross-platform node-gyp build configuration, per-OS/per-arch compiler hardening, sanitizer/static-analysis/CI wiring, and maintainable modern-C++ conventions (RAII, ownership, rule of five, exception safety across the C ABI) with evidence-backed Met/Gap/Not applicable/Needs verification states.",

What it installs
The manifest is a name and a version. 2 skills, 1 agent travel with it, and installing the plugin installs all of them — 365 tokens a session between them. Each is measured on its own page, and each can be installed alone.
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.

cpp is a plugin published in the GitHub repository photostructure/coding-skills (4 stars, last pushed 13d ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
