Installation

Option 1: skills CLI (recommended)

npx skills add DecisionNerd/RedTeam

The skills CLI finds the agents in your project (Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, and others) and asks where to install. Reload your harness, then run /redteam tools.

Update with npx skills update redteam; remove with npx skills remove redteam. The install does not create .redteam/; run /redteam init when you want persistent context. Chat-only commands work without it.

Option 2: Claude Code plugin

/plugin marketplace add DecisionNerd/RedTeam

Then install from the plugin list.

Option 3: ChatGPT Custom GPT

1. Create a Custom GPT
2. Paste chatgpt/INSTRUCTIONS.md from the repo into Instructions
3. Optionally upload skills/redteam/reference/ttp-catalog.md as knowledge

See chatgpt/README.md in the repository.

Option 4: Copy from repo

# Cursor
cp -r .cursor/skills/redteam your-project/.cursor/skills/

# Claude Code
cp -r .claude/skills/redteam your-project/.claude/skills/

# Codex / Agents
cp -r .agents/skills/redteam your-project/.agents/skills/

Run npm run build in the repo first if installing from source.

Option 5: Git submodule

git submodule add https://github.com/DecisionNerd/RedTeam .redteam-plugin
npx skills add ./.redteam-plugin

Requirements

• Node.js 22.12+
• An AI harness that supports skills or slash commands (Cursor, Claude Code, Codex, etc.)

Verify

After install, try:

/redteam tools

You should get a browseable technique catalog with recommendations.
