folio-classify-event is a skill for Claude Code, Codex from alea-institute/folio-mcp. It costs 86 tokens per session (427 once invoked), scanned A, original, MIT.

A guide for classifying events in legal descriptions using FOLIO, a structured vocabulary for legal concepts. It covers categories such as disputes, transactions, bankruptcy, regulation, and employment.

In plain words
What is it for?
Use it to search FOLIO, choose a specific event type, and report its label, identifier, definition, parent category, and confidence.
Why use it?
It gives legal events a consistent label and identifier instead of relying on informal descriptions. The taxonomy also helps find the right level of detail and definition.

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-classify-event 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.

What it actually says

Classify a legal event against the FOLIO ontology's events taxonomy branch.

Workflow

Given a description of a legal event, follow these steps:

  1. Search for matches: Use folio:search_concepts with the event description or key terms to find candidate event types in FOLIO.

  2. Browse the events taxonomy: Use folio:get_taxonomy_branch("events") to review all 14 top-level event categories (e.g., Dispute Events, Transaction Events, Bankruptcy and Restructuring Events, Regulatory Events, Employment Events, etc.).

  3. Drill into the best category: Use folio:get_children(iri) on the most promising category to find the specific event type.

  4. Get full details: Use folio:get_concept(iri) on the best match to retrieve the complete definition, translations, identifiers, and cross-references.

Output Format

Return the classification 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 event type
  • Parent Category: The parent event category in the taxonomy hierarchy
  • Confidence: high / medium / low
  • Reasoning: Brief explanation of why this classification was chosen

If the event spans multiple categories (e.g., a bankruptcy-related dispute hearing), list all applicable types with primary/secondary relevance.

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.
