deep-modules skillA

deep-modules is agent-read markdown (skill) from codybrom/clairvoyance: Measures module depth: whether the interface is simple relative to the implementation behind it. Use when an interface has too many parameters or methods, many small classes each do too little, or methods just forward calls. Not for whether adjacent layers provide different abstractions (use abstraction-quality) or merging/splitting modules (use module-boundaries)..

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

# Deep Modules 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 whether modules provide powerful functionality through simple interfaces.

## When to Apply

- Reviewing a new class, module, or API design
- When a module feels like it "doesn't do enough" or has too many parameters
- When you see many small classes collaborating to do one thing
- When a method signature closely mirrors what it calls
- During refactoring to decide what to merge or deepen

## Core Principles

### The Depth Principle

Every module gives functionality and costs knowledge (in the form of an interface). Deep modules give a lot and ask for very little, delivering the highest return on interface cost. This is the same interface-vs-implementation-cost asymmetry **pull-complexity-down**'s "Core Asymmetry" applies to caller burden — here it's applied to depth.

The deepest possible module can even have no interface at all. Garbage collection is the classic example: it does enormously complex work that callers never think about.

How to install

Latest version
mdr add codybrom/clairvoyance/deep-modules@git:20260722.fcfda01
Exact content
mdr add codybrom/clairvoyance/deep-modules@sha256:d6f6a369bf539fb4

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
