API Contract Review

The goal is to evaluate proposed API contract changes for backward compatibility and provide clear guidance to avoid breaking existing client integrations. The workflow must analyze differences between current and proposed endpoints, determine compatibility risks, and generate a migration and testing plan. It should communicate changes precisely and produce client-friendly release notes.

Prompt Library Organizer

The organization needs a structured workflow to inventory existing prompts and establish a maintainable prompt management system. The goal is to create a clear taxonomy, versioning rules, governance workflow, documentation standards, and deprecation policies while ensuring security and engineering-friendly processes. This will prevent prompt sprawl, reduce confusion, and support long-term maintainability.

Analytics Metric Definition Sheet (Single Source of Truth)

Teams across the organization rely on inconsistent metric definitions, causing confusion, duplicated work, and conflicting dashboards. The goal is to standardize disputed metrics into a single, trusted glossary with clear SQL definitions, filters, grain, and known caveats. The workflow must also define canonical dimensions, governance rules, and a stakeholder announcement to drive alignment.
