Modularity Review (Balanced Coupling)

Audits a codebase for coupling imbalances using Vlad Khononov's Balanced Coupling model and writes an architecture review document.

Dev & CodingAdvanced★ 524⑂ 32AI score 7/10Last updated: Apr 4, 2026

What it does

  • Asks for the analysis scope (whole codebase, a directory, or named components), then reads requirement docs in docs/ and the actual code to map components, responsibilities, and integrations.
  • Surfaces its understanding for you to validate, then asks one targeted question at a time to fill real gaps: domain classification (core/supporting/generic), team ownership, deployment topology, known pain points, strategic direction.
  • For each interacting pair, records the shared knowledge, coupling strength (intrusive / functional / model / contract), distance, and volatility.
  • Applies BALANCE = (STRENGTH XOR DISTANCE) OR NOT VOLATILITY to flag only integrations that are both unbalanced and volatile, and deliberately avoids dumping 30 minor findings.
  • Uses the bundled document skill to produce the review in Markdown and HTML.

Who it's for

  • Architects and tech leads deciding whether a microservice setup has become a distributed monolith.
  • Engineers who need evidence-based explanations for why certain areas are unexpectedly expensive to change.
  • Teams justifying refactoring or service-split proposals with a model instead of gut feel.

Example uses

  • "Review the coupling between the Order and Payment services" → finds shared database tables, classifies it as intrusive coupling across high distance in a volatile area, and ranks it top priority.
  • "Assess the architecture quality of this monorepo" → summarizes components and integration patterns, confirms team boundaries, then emits the review doc.
  • "This module has a lot of unrelated code in it" → diagnoses low cohesion (low strength + low distance) and suggests reorganization without over-decomposing.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/review folder from the GitHub repo vladikk/modularity into my ~/.claude/skills/review/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/vladikk/modularity.git && mkdir -p ~/.claude/skills && cp -r modularity/skills/* ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/vladikk/modularity.git
  3. Make sure the skills directory exists: mkdir -p ~/.claude/skills
  4. This skill depends on balanced-coupling and document, so copy them all: cp -r modularity/skills/* ~/.claude/skills/
  5. Verify with ls ~/.claude/skills that review, balanced-coupling, and document are present.
  6. Start Claude Code inside the project you want to analyze and ask for "a modularity review of this codebase".
  7. Answer its scope/domain/team questions — and keep requirement docs in docs/ — for a much sharper review.
