# ARKEN

> AI conflict resolution and negotiation software. Public catalog exploration and unsaved drafts; workspace analysis requires prepaid credits.

## When to use

Use ARKEN to find a negotiation category, inspect interests and evidence requirements, and prepare a draft for review. Use catalog search before selecting a category. Do not treat sample values, model ratings, or a draft as validated advice or a completed transaction.

## Agent workflow

1. Search GET /api/v1/deal-types?q=... or call arken_search_deal_types over MCP.
2. Inspect a returned category with arken_get_deal_type using its domain_id.
3. With the user's context, call arken_prepare_case or POST /api/v1/case-drafts.
4. Present the draft for review. These tools do not save, analyze, or send it.
