# thinking-red-team

A skill for authorized security review: it models the attacker, maps the attack surface, and keeps only findings with a reproducible exploit path and a verified fix.

## What it does

The skill reviews code, authentication, APIs and data handling you are permitted to probe. It starts by pinning down the target, allowed scope, out-of-scope assets and a success condition such as unauthorized data read or privilege escalation. If authorization is murky, it narrows the scope or refuses outright.

From there it works in steps. It builds a threat model with adversary profiles — anonymous external, authenticated user, privileged insider — maps entry points and trust boundaries, then attempts concrete abuse: input manipulation, authorization gaps, token and session misuse, injection, SSRF, IDOR, mass assignment, rate-limit bypass. Scanner output counts as a lead, not a finding. A pattern only becomes a finding once there is a path you can walk.

An anti-fabrication gate runs through the whole thing. A finding survives only if the chain completes: entry point, ordered steps, realized impact on this code and config. Incomplete paths get dropped rather than relabeled as informational. Each kept finding comes with a minimal fix and a way to re-test that the path is closed. Zero findings is a valid outcome. That is also why you should not point it at systems you lack written permission to test — without authorization it stops.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-red-team -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-red-team -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-red-team -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tjboudreaux/cc-thinking-skills thinking-red-team
```

2. **Manually: put the files in place**
- File: `.github/skills/thinking-red-team/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-red-team -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tjboudreaux/cc-thinking-skills --path skills/thinking-red-team
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/thinking-red-team/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-red-team -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/tjboudreaux/cc-thinking-skills/tree/HEAD/skills/thinking-red-team/SKILL.md

## When to use it
- check whether a control actually blocks the attack instead of just keeping a scanner quiet
- find a reproducible exploit path before launch, not a list of generic advice
- map the attack surface of APIs, file uploads and admin surfaces
- confirm a proposed fix closes the path rather than moving it

## Example prompts
- run a red team review of this API, here is the allowed scope and success condition
- is there an IDOR here with a real exploit path? show me the steps
- test whether the rate limit on this endpoint can be bypassed

# Red Team

Adversarial security review of systems you are authorized to assess. Attack before an outsider does, but report only what you can actually break: every finding needs a concrete exploit path and a check that the proposed fix closes it.

## When to Use

- Security review of code, authentication, authorization, APIs, data handling, or infrastructure you control and are permitted to probe.
- Pre-launch hardening of systems that handle auth, money, personal data, or privileged actions.
- Checking whether a specific vulnerability class (injection, XSS, IDOR, auth bypass, SSRF, secret exposure, etc.) is present with a real path.
- Validating that a claimed control actually blocks the attack, not only that a scanner is quiet.

## When NOT to Use

- No authorization to attack the target — stop; do not probe systems you do not own or have written leave to test.
- Speculative "best practice" notes without a reproducible exploit path — drop them; they are not findings.
- Plan, strategy, or decision stress-testing — use pre-mortem (how the plan fails) or steel-manning (strongest case against the decision).
- Architecture resilience without a security objective — use systems or pre-mortem.
- Scanner output alone as a report — patterns are leads; red-team requires an exploit path.
- Non-security root-cause or hypothesis localization — use scientific-method or five-whys-plus.

## Procedure

1. **Confirm authorization and objective.** State target, allowed scope, out-of-scope assets, success condition (e.g., unauthorized data read, privilege escalation), and stop rules. Refuse or narrow if authorization is unclear.
2. **Build the threat model.** Name adversary profiles (anonymous external, authenticated user, privileged insider) and their goals under realistic access. Attacks without an actor and goal are noise.
