security

security is a plugin for Claude Code from photostructure/coding-skills. Its manifest loads nothing; the 2 skills it bundles cost 300 tokens per session together, scanned A, original, MIT.

A security plugin for reviewing and hardening JavaScript and TypeScript web and Electron applications. Electron is a framework for building desktop apps with web technologies; OWASP ASVS is a security requirements checklist for web applications.

In plain words
What is it for?
Use it to trace web-app data flows, review Electron desktop security, and assess controls such as content policies, login standards, Docker deployment, and other applicable OWASP requirements.
Why use it?
It helps separate confirmed security vulnerabilities from missing protections or items that still need checking, so teams can act on evidence.

Security

Grade A, and why

security 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.

What it installs

The manifest is a name and a version. 2 skills travel with it, and installing the plugin installs all of them — 300 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
