Architecture Optimization

Optimize a working codebase on three axes at once — architecture, code quality, and performance — without breaking what works. This is an interactive, resumable journey of eight phases: the agent asks before every decision and records the outcome in your project's docs/ folder, so you can stop after any phase and pick up later. It is for a system that ships and earns but has grown slow and tangled; the structure phases make the code safe and cheap to change, the performance phases make it measurably fast, and the closing phases keep it that way.

Core Principle

Measure before optimizing, pin before restructuring — the profiler and the safety net decide, not intuition. Premature optimization is the root of much evil not because optimization is bad, but because unmeasured optimization targets the wrong 97% of the code; and a restructure without pinned behavior is a gamble, not an improvement. This skill sequences the phases, asks the decision questions, and records every choice in docs/. The constituent skills carry the method — invoke them rather than improvising their frameworks.
