improve-architecture

name	improve-architecture
description	Audit an area of the codebase and propose the smallest structural moves that improve it - untangle boundaries, kill duplication, fix seams, break cycles. Produces a prioritized plan and decision records, not a rewrite. Use when a codebase feels tangled, hard to change, or is becoming a ball of mud, or when asked to improve or refactor architecture.

improve-architecture

Invest in the shape of the system a little at a time rather than paying for a rewrite later. This skill diagnoses and proposes; it does not rewrite on its own.

Method

1. Map first. Get the current shape before judging it - entry points, modules, data flow, who calls whom. Reuse module-map for the one-screen view; do not skip to opinions.
2. Find the strain. Look for the load-bearing problems, not style nits:
   • God modules that everything imports and nothing can change safely.
   • Leaky boundaries - a module reaching into another's internals instead of its surface.
   • Duplicated logic that drifts (the same rule implemented three ways).
   • Wrong seams - the code is split where it does not bend and fused where it does.
   • Cyclic dependencies.
   • A shape that fights the domain (see domain-modeling - boundaries in code should track boundaries in the language).
3. Propose the smallest move. For each problem, the least change that relieves it: extract a boundary, collapse a duplicate, invert a dependency, move a seam. Prefer a sequence of safe steps over one big cut.
4. Rank by leverage. Order the moves by pain relieved over effort. Say which are safe now and which need a test net first (pair with ).
