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

customs-compliance 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 8d 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

CIEL ADAPTATION: Customs Compliance (Trade Integrity)

This skill formalizes the "Border Layer" of CIEL. It ensures lawful movement of goods across jurisdictions while optimizing duty exposure.

Tariff Classification (GRI Hierarchy)

The Orchestrator MUST apply GRI rules in strict order:

  • GRI 1: Heading text and Section/Chapter notes (resolves ~90%).
  • GRI 3(a): Specificity (prefer "Surgical Gloves" over "Rubber Articles").
  • GRI 3(b): Essential Character (for composite goods and sets).

Compliance Mandates

  1. Restricted Party Screening: Screen Buyer, Seller, Consignee, and Bank against SDN (OFAC) and Entity (BIS) lists.
  2. Prior Disclosure: If a violation is discovered, file a prior disclosure before government investigation begins to cap penalties.
  3. ISF 10+2 (US): File 24 hours before vessel loading.

Documentation Standard

  • Commercial Invoice: Must include description, unit price, Incoterms 2020, and Country of Origin.
  • Valuation: Default to Transaction Value (Method 1). Hierarchically fall back to Deductive or Computed methods if needed.

Anti-Patterns

  • Vibes-Classification: Classifying from a product name alone without technical specs.
  • Incoterm Blur: Using EXW for international trade (creates export compliance burdens for the buyer).
  • Amnesiac Adjudication: Clearing a screening hit without documenting the rationale (date, tool, reason).

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.
