Security
Security agent skills give AI agents disciplined security workflows: code review for vulnerabilities, secret handling, dependency audits, and hardening checklists. Every skill on SkillMD also passes its own safety review before listing, with capability flags shown on each page.
-
hainrixz Skill FixOpt-in fixer (the /claude-seo-ai:fix command). Applies the safe, deterministic SEO/AI-search fixes from a persisted audit to the user's site — meta viewport/charset/lang, JSON-LD, robots.txt AI directives, hreflang, sitemaps, OG/Twitter cards, image dimensions, canonical, AI discovery files — through the adapter that matches the platform (local files, Shopify theme/Admin, WordPress REST/WP-CLI, page APIs, or step-by-step instructions). Dry-run preview by default; writes only after explicit per-change confirmation. Runs only when the user invokes it — never auto-triggered.
-
hainrixz Skill ScoreRecompute and display the two scores (Search SEO + AI Visibility) from a persisted audit run, without re-crawling. Use to re-show or refresh the scores after an audit, to score a specific run directory or host, or to score a saved findings JSON file.

rolemodel Bundle Rails AuditPerform comprehensive code audits of Ruby on Rails applications based on thoughtbot best practices. Use this skill when the user requests a code audit, code review, quality assessment, or analysis of a Rails application.

Outputs a detailed markdown audit report grouped by category (Testing, Security, Models, Controllers, Code Design, Views) with severity levels (Critical, High, Medium, Low) within each category.

tanq16 Skill DevelopThe entry point for any coding work in a project that has these skills installed - implementing a feature, changing or refactoring code, fixing a bug, scaffolding something new, or touching build and CI. Selects and loads the skills that govern the task before any code is written, holds the work to them while coding, and ends with a self-review of the diff against them. Use this first whenever you are about to develop anything. Not for a pure question with no code change, not for writing unit tests, and not for a full audit of an existing codebase.
