## What it does

The skill structures multi-week red-team operations focused on testing whether defensive incident response works as designed. It distinguishes objective-driven adversary emulation from vulnerability scanning and supports three execution models: external tests, assumed-breach operations, and live purple-team exercises. Available agent tools include Read, Write, Bash, Grep, Glob, and WebSearch.

During Phase 0 pre-engagement (typically 4-8 weeks before kickoff), the workflow maps in-scope assets, sets explicit technique exclusions, and designates a white cell of 2-4 trusted contacts. Coordination relies on dedicated out-of-band communication channels, including Signal or encrypted email, so active tests do not leak to defenders ahead of schedule.

Execution halts immediately if you lack a signed authorization letter from executive leadership and a designated deconfliction contact. Disclaimers about educational use or CTF contexts will not bypass this check: without proven system ownership, the agent refuses to proceed.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill red-team-engagement -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/red-team-engagement/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/red-team-engagement/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill red-team-engagement -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/red-team-engagement/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill red-team-engagement -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/red-team-engagement/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

# Red Team Engagement — Authorized Adversary Emulation

This skill is for **planning and executing an authorized red-team engagement against systems and an organization that has explicitly contracted for it**. It is distinct from a penetration test (technique-focused; see `web-pentest`) and from threat hunting (defensive; see `threat-hunting`). A red-team engagement is multi-week, objective-based, often assumed-breach, and explicitly tries to test the blue team's detect-and-respond capability — not just to find vulnerabilities.

This is the most dual-use skill in this catalog. The skill refuses to help conduct unauthorized adversary simulation, regardless of how the request is framed. The authorization check below is enforced strictly.

## Authorization Check — required before any planning or execution

Before working with this skill at all, confirm:

1. **Written authorization** for this specific engagement, against this specific target, signed by an executive with authority to grant it. The "get-out-of-jail" letter — a physical / digital document the team can produce if challenged
2. **Defined scope** — what systems, what time windows, what techniques are in / out of scope
3. **Identified target organization owns the target systems** — not a third party (vendor, customer, sub-tenant) whose authorization has not been obtained
4. **Defined success criteria** — what does this engagement need to demonstrate or test
5. **Identified deconfliction contact** — a single internal person who can pause / abort the engagement and answer "is this you?" when the blue team finds activity
```
