Red-Team Verifier

Red-Team Verifier is a skill for Claude Code, Codex from zgbrenner/agentcounsel. It costs 72 tokens per session (4,186 once invoked), scanned A, original, MIT.

An adversarial review of legal work that looks for invented authorities, unsupported claims, hidden assumptions, weak reasoning, missing jurisdiction details, confidentiality problems, and overconfident wording. It produces findings and a PASS or REVISE verdict for attorney review.

In plain words
What is it for?
Use it to stress-test legal memos, contracts, demand letters, risk matrices, research summaries, draft filings, and other legal analysis.
Why use it?
It exposes weaknesses that a routine review may miss before a legal memo, contract review, filing, or other output is relied upon. A passing result is not legal advice or a substitute for an attorney.

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 Verifier 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.

Red-Team Verifier

Purpose

Adversarially stress-test a legal work product before anyone relies on it. This is AgentCounsel's universal quality-control workflow: it applies to any legal output — a memo, a contract or document review, a demand letter, a risk matrix, a client email, a research summary, a draft filing, or any other analysis — whether the output was produced by an AgentCounsel skill, another AI tool, or a person.

The skill conducts a systematic, category-by-category challenge pass across the draft, hunting for: invented or unverifiable authority; unsupported legal and factual claims; unstated jurisdiction and unverified timing; hidden assumptions and missing facts; weak or incomplete legal reasoning; professional-responsibility problems (language that reads as legal advice, lost attorney-review framing, confidentiality and privilege exposure); confidence overstatement; and structural defects. It produces a verification findings report — a structured set of defects with severity ratings and recommended fixes — plus an overall PASS / REVISE verdict.

It produces draft legal work product for attorney review. It is not legal advice, and a PASS verdict is not a substitute for attorney review.

Use When

  • The user asks to check, sanity-check, or quality-control a legal memo, a contract or document review, a demand letter, a legal analysis, a risk matrix, a client email, a research summary, or a draft filing.
  • The user asks "is this good enough?", "is this ready to send?", or "can I rely on this?"
  • The user asks for the weaknesses, blind spots, or missing issues in a legal draft.
  • The user asks for a hallucination check, a citation check, or a check for invented authority.
  • The user asks whether a draft is ready for — or has been adequately prepared for — attorney review.
  • Any AgentCounsel skill has produced a draft and a defect check is warranted before it is finalized or relied upon.
  • A high-stakes legal output is about to be sent, filed, or acted on and a final adversarial pass is wanted.
  • A draft has been revised and a targeted re-check of the changed sections is needed.

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.
