SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps ensure that changes made to the codebase are consistently reflected across different layers of the project, including runtime code, modeling documentation, validation scripts, and tests, preventing inconsistencies and integration issues.

Core Features & Use Cases

  • Change Scope Identification: Helps identify all affected files and layers by a given change.
  • Cross-Layer Data Flow Verification: Provides a checklist to verify data consistency, error propagation, and guardrail preservation across layers.
  • Code Reuse and Drift Checks: Assists in finding existing patterns and preventing redundant code.
  • Use Case: Before merging a pull request that modifies how financial data is processed, use this Skill to verify that the changes are correctly updated in the runtime code, the artifacts/modelling documentation, and the relevant test cases.

Quick Start

Run git status and git diff --name-only to identify the scope of your changes.

FAQPage Schema
How do I ensure code, docs, and tests stay in sync after modifying runtime logic?

To ensure code, docs, and tests stay in sync, you validate consistency across runtime code, modeling documentation, validation scripts, and tests. This checks that contract fields, error propagation, and guardrails remain synchronized between layers.

What is cross-layer validation in software development?

Cross-layer validation verifies consistency across runtime code, modeling documentation, validation scripts, and tests. It ensures contract fields, error propagation, and guardrails are synchronized, preventing integration issues and drift between project layers.

How do I identify the scope of changes for a pull request?

To identify the scope of changes for a pull request, run git status and git diff --name-only. This identifies all affected files and layers, allowing you to search for usage sites of changed values to prevent drift across the codebase.

How do I prevent code drift and redundant patterns when refactoring?

To prevent code drift and redundant patterns when refactoring, search for usage sites of changed values or patterns. This finds existing patterns, ensuring changes are consistently reflected and preventing redundant code across layers.

Does cross-layer validation work for financial data processing modifications?

Yes, cross-layer validation works for financial data processing modifications. You can verify changes are correctly updated in runtime code, artifacts/modelling documentation, and relevant test cases before merging a pull request.
