Montoyer is an open-source, specialized multi-agent AI framework engineered explicitly to navigate, model, and automate the complex procedural and legal mechanics of European Union governance.

Montoyer replaces the concept of a single "all-knowing" model with specialized actors operating within strict operational boundaries and institutional memory:

• Commissioner Personas: 21 individual portfolio agents (e.g., Competition, Trade, Green Deal) that simulate executive political dynamics and portfolio friction.

• Role Specialists: Dedicated profiles representing the functional tasks of policy officers, legislative drafters, lawyers, and data protection officers (DPOs).

• DG Operational Profiles: Structured profiles modeled after specific Directorates-General to enforce technical, environmental, and financial constraints at runtime.

  Use Case #1: Institutional Policy & Legal Drafting

• The User: Policy Officers and Legislative Drafters within EU Institutions or Permanent Representations.

• The Application: Accelerating the construction of regulatory proposals and staff working documents. By invoking commands like /treaty-check or /legislative-proposal, drafting teams ensure that text instantly respects the Commission's formal style guides, avoids invalid paragraph subdivisions, and explicitly aligns with a validated legal basis.

Use Case #2: Regulatory Compliance & Risk Screening

• The User: Data Protection Officers (DPOs), Case Officers, and Competition Lawyers.

• The Application: Automating intensive vetting workflows. Using the specialized competition-eu domain plugin, users can run automatic /market-definition calculations and cross-reference public infrastructure funding against the General Block Exemption Regulation (/gber-screening) to instantly assess State aid compatibility and check notification thresholds.

Use Case #3: Legislative Stress-Testing & Simulation

• The User: Policy Analysts, Think Tanks, Diplomatic Missions, and Trade Associations.

• The Application: Predictive negotiation tracking. By executing multi-agent simulations of upcoming trilogues or inter-service debates, analysts can anticipate portfolio roadblocks, trace potential amendment vulnerabilities from the European Parliament, and map compromise trajectories within a secure, open-source sandbox.
