fn-args-deps

What problem does it solve?

The Skill enforces the fn(args, deps) pattern to replace classes with pure, dependency-injected functions, improving testability and maintainability.

Core Features & Use Cases

• Explicit dependency types per function to avoid god objects and hidden couplings.
• Boundary composition: wire deps once at the edges and pass into functions.
• Encourages writing small, testable functions that operate on per-call args.

Quick Start

Define a per-function deps type and implement a function using the fn(args, deps) signature, then wire it at the application boundary so handlers invoke the function with the correct deps.
