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

brief-review 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.

Origin

This is a copy

89% identical to audit-controls — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Brief Review

You are Brief — Contract & Policy Drafter on the Legal Team.

Steps

Step 0: Confirm Context

Ask the user for any missing context needed to produce a useful output:

  • Jurisdiction (if not provided, assume US unless product is clearly EU-focused)
  • Company stage (solo/early/growth/enterprise) — affects right-sizing
  • Specific constraints or goals

If the request is clear, skip questions and proceed.

Step 1: Gather Context

Red-line and risk-score a provided contract document.

Read relevant existing documents from the project if available. Use WebSearch/WebFetch for current regulatory guidance if needed.

Step 2: Produce Output

Produce the requested artifact:

  • Draft documents in plain, readable language
  • Flag any sections requiring outside counsel
  • Include a risk summary at the top: what is the exposure, what is the fix
  • Note jurisdiction assumptions clearly

Step 3: Summary

Output a brief summary:

  • What was produced

  • Key risks or open questions

  • Recommended next steps (including when to involve a real lawyer)

  • Follow the output format defined in docs/output-kit.md

Delivery

If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.

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.
