This repository offers a comprehensive collection of over 734 structured cybersecurity skills, meticulously mapped to the MITRE ATT&CK framework and adhering to the `agentskills.io` open standard. It is designed to empower AI agents, enabling them to discover, understand, and execute complex cybersecurity tasks. The primary benefit is providing a standardized, machine-readable format for cybersecurity knowledge, facilitating seamless integration into various AI development tools and workflows for cybersecurity professionals and AI developers.

How It Works

The project leverages the `agentskills.io` progressive disclosure pattern. Each cybersecurity skill is defined with a concise YAML frontmatter containing essential metadata like name, description, domain, and tags. This allows AI agents to quickly assess skill relevance using minimal computational resources and tokens. If a skill matches the AI's task, the full content—including detailed workflow steps, prerequisites, tool commands, and verification procedures—is then loaded for execution. This approach optimizes AI agent performance by avoiding the processing of irrelevant, lengthy skill details.

Quick Start & Requirements

• Primary install / run command:
  • npx skills bash
  • npx skills add mukul975/Anthropic-Cybersecurity-Skills
  • Claude Code plugin: /plugin marketplace add mukul975/Anthropic-Cybersecurity-Skills
  • Manual clone: git clone https://github.com/mukul975/Anthropic-Cybersecurity-Skills.git
• Non-default prerequisites and dependencies: Node.js and npm/npx are required for the npx commands. Individual skills may necessitate specific cybersecurity tools (e.g., Volatility3, Burp Suite, Wireshark, Ghidra, Sliver C2, etc.), which are detailed within each skill's documentation. No specific hardware (GPU, CUDA) or OS is mandated by the collection itself.
• Estimated setup time or resource footprint: Basic integration via npx or cloning is rapid (minutes). Actual execution time and resource usage depend heavily on the complexity and dependencies of the specific cybersecurity skill being invoked.

Maintenance & Community

This project is identified as an independent, community-created collection, explicitly stating it is "Not affiliated with Anthropic PBC." Contributions are welcomed, with guidelines provided in a `CONTRIBUTING.md` file. The README does not specify dedicated community channels like Discord or Slack, nor does it list prominent maintainers or sponsorships.

Licensing & Compatibility

• License type: Apache License 2.0.
• Compatibility notes: The Apache 2.0 license is permissive, generally allowing for commercial use and integration into closed-source projects without significant copyleft restrictions. The skills are designed for broad compatibility across AI agent platforms supporting the agentskills.io standard.

Limitations & Caveats

The repository is a community project and carries a disclaimer of non-affiliation with Anthropic PBC. While the skills are standardized for AI agents, their practical execution is contingent upon the user having the necessary underlying tools and environments pre-installed and configured. The README does not provide specific performance benchmarks or known bug lists for the skills.
