SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires zod, packages/shared-types, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Cross-boundary QA provides a structured methodology to validate boundary correctness across modules (API ↔ Frontend, DB ledger ↔ UI, and external payment flows) to prevent cross-module integration issues.

Core Features & Use Cases

  • Boundary Pair validation across API, frontend hooks, dashboards, and ledgers for end-to-end consistency.
  • Incremental QA workflow: verify each module as it completes (products, carts, orders, payments, referrals) instead of a late-stage full test.
  • Script-driven verification: place QA scripts in scripts/qa/ and use references/boundary-bug-patterns.md for checklists, with automated reporting to _workspace/04_qa_report.md.
  • Real-world use cases include end-to-end referral earnings validation, refund/REVERT handling, and abuse scenario reproduction.

Quick Start

Boot the local stack and seed data, then run the QA script suite in scripts/qa/run-all.ts to verify boundary integrity across modules.

FAQPage Schema
What is cross-boundary QA and when do I need it for end-to-end workflows?▼

Cross-boundary QA validates boundary consistency across API, frontend, and data stores to prevent cross-module integration issues. You need it for end-to-end commerce workflows, including API↔Frontend, DB ledger↔UI, and payment webhook interactions.

How do I validate API and frontend boundary consistency after adding new commerce modules?▼

You can validate boundary consistency incrementally as each module completes by running script-driven verification. Place QA scripts in scripts/qa and execute the suite to verify boundary integrity across modules like products, carts, orders, and payments.

Can I automate end-to-end validation for referral earnings and payment webhook interactions?▼

Yes, you can automate end-to-end validation for referral earnings, refund handling, and payment webhook interactions. The Skill uses script-driven checks in scripts/qa and references boundary-bug-patterns.md to reproduce abuse scenarios and validate boundary pairs.

How do I generate structured QA reports for cross-module integration testing?▼

You generate structured QA reports by running the QA script suite, which automatically outputs results to _workspace/04_qa_report.md. This report captures boundary-pair check results across API, frontend hooks, dashboards, and ledgers.

Does this cross-boundary validation approach support incremental testing instead of late-stage full tests?▼

Yes, it supports an incremental QA workflow that verifies each module as it completes, including products, carts, orders, payments, and referrals. This prevents late-stage full test failures by catching cross-module integration issues early.

What are common boundary bug patterns when integrating DB ledgers with frontend UI?▼

Common boundary bug patterns include inconsistencies between DB ledgers and UI dashboards, API and frontend hook mismatches, and incorrect payment webhook state transitions. The references/boundary-bug-patterns.md file provides a checklist for pattern-based checks.
