planning-data-architecture

What problem does it solve?

This Skill prevents data model drift by producing a story-scoped data architecture that is validated against the story requirements and any consumed shared contracts.

Core Features & Use Cases

• Per-story data discovery: Reads story scope and supporting architecture docs to identify entities, relationships, and implied access patterns.
• Contract-aligned schema design: Uses consumed contracts as authoritative for shared entities and ensures schema supports required contract terms.
• Index- and lifecycle-aware output: Maps read/write patterns to indexes, defines integrity and migration considerations, and writes the final architecture to the story’s data document.

Quick Start

Use planning-data-architecture for a specific user story by asking it to produce data architecture for US-NNN-name and write the result to plan/user-stories/US-NNN-name/data.md.
