red-team

red-team is a skill for Claude Code from larsboes/Axon. It costs 128 tokens per session (1,021 once invoked), scanned A, original, MIT.

A review workflow that challenges one proposal by breaking it into testable claims, stating its strongest case, and then examining its weaknesses. It ranks the findings and gives a test for resolving each one.

In plain words
What is it for?
Use it to stress-test plans, designs, or decisions when you want counterarguments, severity levels, and evidence-based checks.
Why use it?
It provides a disciplined way to find important problems before a proposal is implemented, instead of collecting vague objections or personal preferences.

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

red-team 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

red-team

One proposal goes in. The strongest honest case for it and the strongest surviving case against it come out, with each objection ranked and testable.

Red-team attacks a single proposal. To weigh options against each other, use council.

Adapted from the RedTeam skill in LifeOS by Daniel Miessler (https://github.com/danielmiessler/LifeOS), MIT.

Procedure

Copy this checklist and track progress:

- [ ] 1. Restate the proposal as atomic claims
- [ ] 2. Write the steelman
- [ ] 3. Attack every claim through the lenses
- [ ] 4. Rank the findings by severity
- [ ] 5. Name the one core issue
- [ ] 6. Report, and hand off if the answer is a choice

1 — Atomic claims. Read references/method.md and split the proposal into claims that are each independently true or false. A claim that cannot be false is a preference. Move it out of the list and say so.

2 — Steelman. Write the version of the proposal its author would sign. Fix its weak wording, supply the argument it left implicit, and use its best evidence. Attacking a proposal you first made weaker proves nothing.

3 — Attack. Read references/lenses.md and run each lens against every claim. Run the lenses as parallel red-team-lens subagents, one lens per agent, when the proposal is longer than a page or the claims need files read. Run them inline otherwise. A lens reads files; it never runs a command and never edits one, so any measurement it is allowed to cite has to be in its prompt.

4 — Rank. Sort every surviving finding into fatal, structural, cost or cosmetic. Discard anything that only restates a claim in a hostile tone. Volume is not signal.

5 — The core issue. Name the single assumption that, if false, collapses the rest. Most proposals have exactly one. Say so if this one has none.

6 — Report. Follow references/output-format.md. Every finding carries a remediation and a test that would settle it.

What counts as a finding

  • A stated claim that is false, and the evidence that it is false.
  • An unstated assumption the proposal needs and never argues.
  • A step that does not follow from the step before it.
  • A category error: the proposal treats one thing as another and inherits the wrong rules.
  • A precedent that already went the other way, cited.

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.
