Patterns

Reference architectures

Governance designs for common agentic workflows. Each pattern shows the flow, the controls that hold it accountable, its escalation paths, and the lessons learned. Where one exists, it also includes a worked before-and-after assessment.

Legal Services Recommendation

Legal Matter Intake

An agent that receives inbound matters, extracts key facts, classifies matter type, and proposes a routing, leaving the assignment decision to a human.

Legal Services Advice

Client Communication Drafting

An assistant that drafts client communications for a professional to review and send, with drafting-only authority enforced in code, because the defining risk at this band is authority creep.

An agent that moderates user content against policy, auto-actioning clear cases and escalating the ambiguous ones.
