+# Anthropic Cybersecurity Skills Integration
+
+Import and use the Anthropic Cybersecurity Skills library (754 skills, 26 domains, 5 frameworks) with Hermes Agent.
+
+## Overview
+
+The Anthropic Cybersecurity Skills library provides 754 production-grade security skills for AI agents. Each skill follows the agentskills.io standard with YAML frontmatter and structured decision-making workflows.
+
+## Source
+
+- **Repository:** https://github.com/mukul975/Anthropic-Cybersecurity-Skills
+- **License:** Apache 2.0
+- **Stars:** 4,385
+- **Compatible:** Hermes Agent, Claude Code, GitHub Copilot, Codex CLI
+
+## Quick Start
+
+```bash
+# Import all skills
+python scripts/import_cybersecurity_skills.py
+
+# Import by domain
+python scripts/import_cybersecurity_skills.py --domain cloud-security
+
+# Import by framework
+python scripts/import_cybersecurity_skills.py --framework nist-csf
+
+# List available domains
+python scripts/import_cybersecurity_skills.py --list-domains

+
+# Dry run (show what would be imported)
+python scripts/import_cybersecurity_skills.py --dry-run
+```
+
+## Security Domains (26)
+
+| Domain | Skills | Key Capabilities |
+|--------|--------|-----------------|

+| Container Security | 30 | K8s RBAC, image scanning, Falco, container forensics |
+| OT/ICS Security | 28 | Modbus, DNP3, IEC 62443, SCADA |
+| API Security | 28 | GraphQL, REST, OWASP API Top 10, WAF bypass |
+| Vulnerability Management | 25 | Nessus, scanning workflows, CVSS |
+| Incident Response | 25 | Breach containment, ransomware response, IR playbooks |

+
+## Framework Mappings (5)
+
+| Framework | Version | Scope |
+|-----------|---------|-------|
+| MITRE ATT&CK | v18 | 14 tactics, 200+ techniques |
+| NIST CSF 2.0 | 2.0 | 6 functions, 22 categories |
+| MITRE ATLAS | v5.4 | 16 tactics, 84 techniques |
+| MITRE D3FEND | v1.3 | 7 categories, 267 techniques |
+| NIST AI RMF | 1.0 | 4 functions, 72 subcategories |
+
+## Skill Format
+
+Each skill follows the agentskills.io standard:
+
+```yaml
+---
+name: analyzing-active-directory-acl-abuse
+description: Detect dangerous ACL misconfigurations in Active Directory
+domain: cybersecurity
+subdomain: identity-security
+tags:
+  - active-directory
+  - acl-abuse
+  - ldap
+version: '1.0'
+author: mahipal
+license: Apache-2.0
+nist_csf:
+  - PR.AA-01
+  - PR.AA-05
+  - PR.AA-06
+---
+```
+
+## Use Cases for Hermes
+
+1. **Fleet security** — Agents can audit their own infrastructure
+2. **Incident response** — Structured IR playbooks for security events
+3. **Threat hunting** — Hypothesis-driven hunts across fleet logs
+4. **Compliance** — Framework-mapped skills for audit preparation
+5. **Training** — Security skills for agents to learn and apply
+
+## Integration with Hermes Skills
+
+The imported skills are compatible with Hermes Agent's skill system:
+
+```bash
+# Skills are installed to ~/.hermes/skills/cybersecurity/
+# Each skill has a SKILL.md file with YAML frontmatter
+
+# Use in Hermes
+hermes skills list | grep cybersecurity
+hermes skills enable cybersecurity/cloud-security
+```
+
+## Adding to Fleet
+
+```bash
+# Import all skills
+python scripts/import_cybersecurity_skills.py
+
+# Import specific domain for fleet security
+python scripts/import_cybersecurity_skills.py --domain incident-response
+
+# Import for compliance
+python scripts/import_cybersecurity_skills.py --framework nist-csf
+```
+
+## Index
+
+After import, an index is generated at `~/.hermes/skills/cybersecurity/index.json` listing all installed skills with their metadata.
