module-boundaries skillA

module-boundaries is agent-read markdown (skill) from codybrom/clairvoyance: 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)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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
