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

folio-identify-area-of-law 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 2mo 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

What it actually says

Identify Areas of Law with FOLIO

Identify the area(s) of law that apply to a legal situation using the FOLIO ontology's areas_of_law taxonomy branch.

Workflow

Given a description of a legal situation or matter, follow these steps:

  1. Search for relevant areas: Use folio:search_concepts with key legal terms from the situation to find candidate areas of law.

  2. Browse all areas of law: Use folio:get_taxonomy_branch("areas_of_law") to review all 31 top-level areas of law. This ensures you do not miss a relevant area that the search might not surface.

  3. Check sub-specialties: Use folio:get_children(iri) on promising top-level areas to see if a more specific sub-specialty applies.

  4. Get full details: Use folio:get_concept(iri) on each matching area for the complete definition, translations, and cross-references.

Output Format

Return each applicable area of law as:

  • FOLIO Label: The official FOLIO concept name
  • FOLIO IRI: The concept's unique identifier (e.g., https://folio.openlegalstandard.org/...)
  • Definition: The FOLIO definition of this area of law
  • Relevance: primary (directly applicable) or secondary (tangentially related)
  • Reasoning: Brief explanation of why this area applies to the situation

List primary areas first, then secondary areas. Most situations involve 1-3 primary areas and 0-2 secondary areas.

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.
