general-vs-special skillA

general-vs-special is agent-read markdown (skill) from codybrom/clairvoyance: Evaluates whether interfaces are appropriately general-purpose. Use when checking interface generality, when if-branches or parameters serve only one caller, or when getters/setters expose internal representation. Not for information leakage across boundaries (use information-hiding) or auditing configuration parameters (use pull-complexity-down)..

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

# General vs. Special-Purpose 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.

General-purpose modules are surprisingly simpler, deeper and less effort to build. They produce better information hiding and can even provide these benefits when used in a single context. Because a general-purpose interface doesn't need to know about specific callers, the knowledge always stays where it belongs.

## When to Apply

- Designing a new module, API, or utility
- When a module has use-case-specific logic embedded in it
- When a module's interface is cluttered with rarely-used parameters
- When deciding between a flexible API and a specific one

## Core Principles

### The Generality Test

> "What is the simplest interface that will cover all my current needs?" — John Ousterhout, _A Philosophy of Software Design_

Not "the most general interface possible." The target is **somewhat general-purpose**.

- **Functionality**: Scoped to current needs. Doesn't build features you don't need.
- **Interface**: General enough to support multiple uses. Doesn't tie it only to today's caller.
