des-data-source-assessment
CommunityValidate data sources before modeling
System Documentation
What problem does it solve?
This Skill prevents data engineering projects from proceeding with unsuitable, inaccessible, unowned, low-quality, or legally risky source systems by creating a rigorous Data Source Inventory and evidence-backed assessment before downstream design starts.
Core Features & Use Cases
- Source inventory and assessment: Identify and classify candidate source systems (types, generation patterns, ownership, access methods, and evidence).
- Evidence-driven validation: Capture or reference probe/sample/schema/docs evidence for key sources, and explicitly mark Unknown/Risk/Blocked when evidence is missing.
- Risk-aware handoff for Phase 06: Produce Phase 05 artifacts (support plan, evidence pack, revision, done gate, and handoff) so domain modeling can safely proceed with clear source-of-truth decisions and constraints.
Quick Start
Use des-data-source-assessment after you have Phase 04 Data Product Specification and the Phase 04-to-05 handoff, to produce _des-output/planning-artifacts/05-data-source-inventory.md with verified source mappings, evidence statuses, and a ready-to-model Phase 05 handoff.
