Description

How It Works
This workflow automates legal policy governance for legal teams, policy managers, and compliance officers, eliminating manual document review, approval classification, and multi-channel stakeholder distribution. Submitted policy documents are form-triggered, extracted into structured text, and passed to the Legal Governance Agent. Backed by shared memory and a governance model, it coordinates three specialist agents: Policy Analysis (content evaluation), Compliance Tracking (regulatory alignment), and Legal Summary (structured report generation). Gmail and Slack notification tools handle multi-channel alerts in parallel. Outputs are parsed and routed by approval status across four concurrent Google Sheets tracks: policy record storage with stakeholder notifications, approval preparation and tracking, compliance record preparation and tracking, and audit log generation, ensuring a complete, audit-ready governance trail for every submission.
