Overview

Hunter Skill is a standardized cybersecurity skills knowledge base containing ~250+ skill files organized across three major sources:

  • PayloadsAllTheThings (~100+ files) - Exploit techniques and payloads
  • h4cker (~50+ files) - Programming and security resources
  • HackTricks (~100+ files) - Penetration testing techniques

Each skill is structured as JSON following the SKILL_SCHEMA.json v1.0.0 specification, enabling:

  • 🔍 Automated validation against schema
  • 🔄 Automated migration from legacy formats
  • 🏷️ Rich metadata for discoverability
  • ✨ Consistent structure across all files
  • 📊 Compliance tracking and reporting

Working with Skills Programmatically

import json
from pathlib import Path

# Load a single skill

    with open(file_path) as f:
        return json.load(f)

# Find all skills in category
def find_by_category(directory, category):
    results = []
    for file_path in Path(directory).glob("*.json"):
        try:
            skill = load_skill(file_path)
            if skill['classification']['category'] == category:
                results.append(skill)
        except (json.JSONDecodeError, KeyError):
            pass
    return results

# Find by tag
def find_by_tag(directory, tag):
    results = []
    for file_path in Path(directory).glob("*.json"):
        try:
            skill = load_skill(file_path)
            if tag in skill['classification'].get('tags', []):
                results.append(skill)
        except (json.JSONDecodeError, KeyError):
            pass
    return results

# Example usage
cve_skills = find_by_category('skills/', 'CVE Exploits')
rce_skills = find_by_tag('skills/', 'rce')

for skill in cve_skills:
    print(f"{skill['content']['title']} - {skill['metadata']['id']}")

FAQ

General Questions

Q: What is Hunter Skill?
A: Hunter Skill is a standardized cybersecurity knowledge base with ~250+ skill files in JSON format, validated against a JSON schema.

Q: How many skills are in the database?
A: Currently ~250+ skills across three sources (PayloadsAllTheThings, h4cker, HackTricks).

Q: Is this ready for production?
A: Yes! The schema, tools, and documentation are complete. Migration can begin immediately following IMPLEMENTATION_ROADMAP.md.

Q: How often is it updated?
A: The skill sources (PayloadsAllTheThings, HackTricks, h4cker) are regularly updated. Hunter Skill can be synced accordingly.

Technical Questions

Q: What format are skills in?
A: JSON format following SKILL_SCHEMA.json v1.0.0 specification.

Q: Can I validate my own skills?
A: Yes! Run python3 scripts/validate_skills.py your_file.json to validate any skill file.

Q: What if validation fails?
A: Review the error message and check SKILL_SCHEMA.json and MIGRATION_GUIDE.md (Troubleshooting section).

Q: How do I migrate from old format?
A: Use python3 scripts/migrate_skills.py - see MIGRATION_GUIDE.md for detailed instructions.

Implementation Questions

Q: How long does migration take?
A: 4-6 weeks with 3 people, 12-18 hours total effort. Can be done incrementally.

Q: Will migration break my existing tools?
A: Only if they directly access field names. Most can be updated easily - see MIGRATION_GUIDE.md.

Q: What if something goes wrong during migration?
A: Automatic backups are created in skills_backup/. Restore with cp -r skills_backup/* skills/.

Q: Can I migrate incrementally?
A: Yes! Use --category flag to migrate specific categories, or follow Phase 2 (Pilot) approach.
