Overview

claude-red is a curated library of offensive security skills for the Claude Skills system. Each skill is a structured SKILL.md file that primes Claude with expert-level methodology for a specific attack surface — from SQL injection to shellcode, EDR evasion to ADCS abuse.

Drop a skill into your Claude environment and it behaves like a domain specialist: it knows the techniques, the tooling, the edge cases, and the escalation paths. Skills load on demand based on conversational triggers — you don't pay context for skills you aren't using.

Use cases: authorized red team engagements, bug bounty triage, security research, CTF preparation, operator training, and methodical attack surface exploration.

Quickstart

Claude Skills System (Recommended)

git clone https://github.com/SnailSploit/claude-red ~/.claude/skills/claude-red

Claude auto-loads matching skills based on conversational triggers (e.g., mentioning SQL injection loads offensive-sqli).

To install a single category:

git clone --filter=blob:none --sparse https://github.com/SnailSploit/claude-red
cd claude-red && git sparse-checkout set Skills/web Skills/active-directory

Claude Code

cat Skills/web/offensive-sqli/SKILL.md | claude --system-file -

cat Skills/active-directory/**/SKILL.md | claude --system-file -

Claude.ai (Manual)

Paste the contents of a SKILL.md into a Project's system prompt or prepend it to your conversation.

Install Script
