SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Validates that a project maintains a single, versioned codebase across deployments to prevent drift and governance issues.

Core Features & Use Cases

  • Detects multiple deployments derived from the same root commits and ensures proper boundaries between applications.
  • Maps the relationship: application -> codebase -> deployments, to aid audits and refactors.
  • Supports governance scenarios for monorepos and multi-repo architectures to help determine when to consolidate or split codebases.

Quick Start

Run a quick audit to confirm the codebase is single and uniquely versioned across deployments.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I verify a single versioned codebase across multiple deployments?

Verify a single versioned codebase across multiple deployments by auditing shared root commits and mapping application boundaries to ensure no drift exists between deployments.

What is the best way to audit codebase boundaries in a monorepo architecture?

Auditing codebase boundaries in a monorepo involves mapping the relationship of application to codebase to deployments, detecting shared root commits, and explicitly defining governance boundaries.

When do I need to audit my codebase for twelve-factor compliance?

You need to audit your codebase for twelve-factor compliance during refactors, governance reviews, or when managing multi-repo architectures to prevent drift and ensure proper deployment tracking.

Can I use this to detect multiple deployments sharing the same root commit?

Yes, you can detect multiple deployments sharing the same root commit by running a codebase audit that identifies shared origins and explicitly maps application to base code to deployments.

How do I map applications to their base code and deployments for governance?

Map applications to their base code and deployments by running an audit that outputs explicit boundaries and tracks derivation from root commits across your monorepo or multi-repo architecture.

What are the limitations of auditing codebase boundaries in multi-repo architectures?

Auditing codebase boundaries in multi-repo architectures requires explicit boundary definitions to detect shared root commits accurately, and may not resolve governance issues without proper versioning and deployment tracking.
