RedTeam

RedTeam is a skill for Claude Code, Codex from danielmiessler/LifeOS. It costs 90 tokens per session (1,236 once invoked), scanned A, original, MIT.

An adversarial review that breaks an idea or plan into claims, tries to disprove them, and reports ranked weaknesses with fixes.

In plain words
What is it for?
Use it to stress-test strategies, designs, proposals, decisions, and plans from several expert perspectives.
Why use it?
It helps expose hidden assumptions, risks, and counterarguments before they cause problems in practice.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

RedTeam scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Customization

Before executing, check for user customizations at: ~/.claude/LIFEOS/USER/CUSTOMIZATIONS/SKILLS/RedTeam/

If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.

🚨 MANDATORY: Voice Notification (REQUIRED BEFORE ANY ACTION)

You MUST send this notification BEFORE doing anything else when this skill is invoked.

  1. Send voice notification:

    curl -s -X POST http://localhost:31337/notify \
      -H "Content-Type: application/json" \
      -d '{"message": "Running the WORKFLOWNAME workflow in the RedTeam skill to ACTION"}' \
      > /dev/null 2>&1 &
    
  2. Output text notification:

    Running the **WorkflowName** workflow in the **RedTeam** skill to ACTION...
    

This is not optional. Execute this curl command immediately upon skill invocation.

RedTeam Skill

What It Does

Attacks ideas, strategies, and plans to find their weak points before reality does. It breaks an argument into atomic claims, deploys many parallel expert agents (engineers, architects, pentesters, interns) to stress-test each one, then synthesizes the findings into a steelman of the argument plus the strongest counter-argument against it.

The Problem

People fall in love with their own plans. Once you've committed to an idea, your brain hunts for reasons it works and skips past the reasons it doesn't — and the people around you are often too polite or too aligned to push hard. So flawed strategies sail through unchallenged until they fail in production, in the market, or in the meeting where someone finally asks the hard question. This skill is the hard question, run many ways at once: it attacks the argument deliberately and at volume so the weak points surface while they're still cheap to fix.

How It Works

Military-grade adversarial analysis using parallel agent deployment. It breaks arguments into atomic components, attacks from many expert perspectives (engineers, architects, pentesters, interns), synthesizes findings, and produces sharp counter-arguments alongside the steelman version of the case. Targets arguments, not network vulnerabilities.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
