web-security-hardening skillA

web-security-hardening is agent-read markdown (skill) from photostructure/coding-skills: Security best-practices and hardening review for JavaScript/TypeScript web and Electron desktop applications. Use when asked to harden an app, review security posture or secure defaults, assess OWASP ASVS or Electron security-checklist alignment, improve HTTP headers or CSP, review forms/input validation/sanitization/uploads, strengthen authentication/passwords/sessions/secrets, secure Electron windows/preloads/IPC/navigation/permissions/protocols/updates/packaging, or evaluate deployment/operat.

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.

How to install

Latest version
mdr add photostructure/coding-skills/web-security-hardening@git:20260820.d8935aa

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.
