SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Architectural drift and system health can go unnoticed when changes seem locally benign; this Skill provides periodic, cross-cut checks to ensure the overall architecture remains healthy.

Core Features & Use Cases

  • Establishes weekly architecture-health checks that monitor layer boundaries, coupling trends, and complexity hotspots.
  • Detects drifting metrics such as increasing inter-module coupling, layer violations, and hotspot file growth to guide refactoring and governance.
  • Use Case: In a large codebase, run weekly GC checks to surface architecture drift and generate actionable insights for the engineering team.

Quick Start

Configure and run a weekly fitness-function sweep to monitor the architecture using dependency metrics and GC tooling.

Frequently Asked Questions about fitness-functions

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

FAQPage Schema
How do I monitor architectural drift and detect layer boundary violations in a large codebase?▼

Monitor architectural drift by running weekly system-wide health checks that track layer boundaries, coupling trends, and hotspot complexity. This approach identifies increasing inter-module coupling, layer violations, and hotspot file growth to guide refactoring.

What is a fitness function sweep for software architecture health checks?▼

A fitness function sweep is a weekly architectural health check that computes dependency metrics, code churn, and complexity. It generates weekly snapshots to quantify system-wide architectural drift over time and keep large-scale software projects aligned.

How do I set up weekly governance cycles to track coupling trends and complexity hotspots?▼

Set up weekly governance cycles by configuring a fitness-function sweep to monitor architecture using dependency metrics and tooling. This generates weekly snapshots for comparison against prior runs and tracks coupling trends across modules.

Can I use fitness functions to monitor architectural health for large-scale software projects?▼

Yes, fitness functions are specifically applicable to large-scale software projects with weekly governance cycles. They require tooling to compute dependency metrics, code churn, and complexity to detect drifting metrics and generate actionable insights.

Do I need specific tooling to compute dependency metrics and code churn for architectural health monitoring?▼

Yes, you need tooling to compute dependency metrics, code churn, and complexity to run weekly fitness-function sweeps. This tooling generates the weekly snapshots required for HARNESS.md alignment, comparison against prior runs, and agent interpretation.

Why does architectural drift go unnoticed when changes seem locally benign?▼

Architectural drift goes unnoticed because local code changes appear benign in isolation. Periodic, cross-cutting fitness function checks are required to surface system-wide issues like increasing inter-module coupling and layer violations over time.
