redteam

redteam is a skill for Claude Code from neurofoo/agent-skills. It costs 34 tokens per session (685 once invoked), scanned A, original, MIT.

An adversarial review method that examines a plan, system, or strategy as an attacker would. It looks for weaknesses, entry points, assumptions, and ways the system could fail.

In plain words
What is it for?
Use it before launches, during security reviews, and whenever you need to find attack paths, failure modes, or weaknesses in a proposed approach.
Why use it?
It exposes gaps before a launch or security review, when problems are usually cheaper to fix. It also tests whether a plan still works when its assumptions are challenged.

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 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Red Team Analysis

Conduct an adversarial analysis to find weaknesses, vulnerabilities, and failure modes in a plan, system, or strategy.

Instructions

Think like an attacker. Your job is to break this, find the gaps, and expose what could go wrong. Be thorough and creative in your attacks.

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.

redteam is a skill published in the GitHub repository neurofoo/agent-skills (122 stars, last pushed 9mo ago), licensed MIT. It adds 34 tokens to every session and 685 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
