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

redline 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 10d 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.

What it actually says

Invoke the redline-analysis-agent sub-agent to compare contract versions.

Provide version details:

$ARGUMENTS

The agent supports two modes:

  • Mode A — Automated redline: provide v1 path and v2 path
  • Mode B — Targeted clause analysis: provide clause reference and both versions

The agent will:

  1. Parse both versions and identify every change
  2. Classify each change: Typographical / Substantive / Deal-Breaker
  3. Flag modal verb shifts (SHALL → WILL etc.) as automatic Substantive changes
  4. Assess commercial impact per change
  5. Generate redline-[YYYYMMDD-HHMM].docx with tracked changes table + .html

HITL Gate fires before output — respond with APPROVED or REVISE: [focus areas].

Usage: /redline SHA_v1.txt SHA_v2_counterparty.txt or /redline Clause 8.2 — SHALL changed to WILL

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.
