## Installation

### Method 1 — npx (recommended)

```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills

This clones and installs all skills into your project's .skills/ directory, making them auto-discoverable by any agentskills.io-compatible agent.

Method 2 — Claude Code plugin marketplace

/plugin marketplace add mukul975/Anthropic-Cybersecurity-Skills

Method 3 — Manual clone

git clone https://github.com/mukul975/Anthropic-Cybersecurity-Skills.git
# Copy or symlink the skills/ directory into your project
cp -r Anthropic-Cybersecurity-Skills/skills .skills

Method 4 — pip / Python package (helper scripts)

pip install agentskills   # agentskills.io CLI if available
# or use the bundled Python scripts directly from the repo

Skill Directory Structure

After installation, each skill lives at:

.skills/{skill-name}/
├── SKILL.md            # YAML frontmatter + full workflow
├── references/
│   ├── standards.md    # NIST, MITRE ATT&CK, CVE mappings
│   └── workflows.md    # Deep technical procedures
├── scripts/
│   └── process.py      # Practitioner helper scripts
└── assets/
    └── template.md     # Checklists and report templates

How Skills Work (Progressive Disclosure)

AI agents read only the YAML frontmatter (~30–50 tokens) during discovery. If the skill matches the task, the full body is loaded.
