Evaluates where module boundaries are drawn and whether modules should be merged or split. Use when deciding whether to combine or separate two modules, when modules are tightly coupled, or when a change to one forces changes to another. Not for depth within a single module (use deep-modules) or abstraction-layer quality (use abstraction-quality).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Module Boundaries Review Lens

When invoked with $ARGUMENTS, focus the analysis on the specified file or module. Read the target code first, then apply the checks below.

Evaluate where module boundaries are drawn: are related things together and unrelated things apart?

## When to Apply

- Deciding whether to split a large class or merge small ones
- When two modules seem tightly coupled
- When a change to one module frequently requires changes to another
- When reviewing a decomposition decision

## Core Principles

### The Default Instinct Is Wrong

Most developers assume smaller is better, which produces systems full of shallow, pass-through components that increase cognitive load without hiding anything. The right answer is always whichever arrangement results in lower overall system complexity. Not smaller. Not more separated. Simpler.

### Merge Signals (Better Together)

- **They share information**: Same format, protocol, or data structure knowledge
- **They simplify each other**: Together, code is simpler than pieces apart
- **They always change together**: The boundary is fiction
- **One is incomplete without the other**: Callers must always use both

How to install

The exact contents, by fingerprint
mdr add codybrom/clairvoyance/module-boundaries@sha256:b71cbc80defbf1a8

The line at the top of this page pins the label git:20260722.fcfda01, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
