Secure Claude Code on macOS by deploying PreToolUse and PostToolUse hooks that block secret exfiltration, prompt injection, persistence, and self-tampering during tool execution.
npx claudepluginhub extractumio/extractum-skills --plugin harden-macos-claudeA curated collection of production-ready skills, agents, and automation tools for Claude Code, created by the Extractum Team.
This repository contains reusable skills and resources that extend Claude Code's capabilities. Skills are structured procedures that Claude can invoke to perform complex, multi-step operations — from DevOps automation and agent scaffolding to domain-specific research and analysis workflows.
The collection is organized into categories (general-purpose, domain-specific, DevOps, computer-use, agents, and more) and is continuously evolving. Browse the directories to discover what's available.
Skills are structured knowledge documents that give Claude step-by-step guidance for performing specific tasks. They can include documentation, reference templates, executable scripts, and hook configurations. Each skill follows a standard format with frontmatter metadata (name, description) and markdown instructions.
Skills may also ship with supporting scripts, command definitions, or configuration files — whatever is needed to get the job done.
Copy any skill into your project's .claude/skills/ directory. Claude Code will automatically detect and use it:
cp -r <skill-directory> /path/to/your/project/.claude/skills/
Clone the repo and browse for skill templates, patterns, and examples to adapt to your own workflows:
git clone https://github.com/extractum-io/claude-skills.git
