Tidy

You just finished coding with an AI agent. The feature works and tests might pass, but git status shows a messy diff: orphaned helpers from earlier prompts, dead types, bloated prompt instructions, cosmetic churn that obscures the real change, or retries and special cases for situations that almost never happen.

melech-tidy is the universal, adaptive diff reduction engine.

Instead of forcing you to diagnose whether your diff suffers from dead code, prompt bloat, cosmetic noise, or rare-case handling that costs more than it buys, melech-tidy audits your diff, categorizes findings into four mutually exclusive reduction lanes, presents a concrete evidentiary table, and executes surgical cleanups with your approval. Every lane only recommends; you choose what gets tidied.

Tidy subtracts; it does not move code between seams or re-architect.

The 4 Mutually Exclusive Reduction Lanes

The agent reads the requested outcome and surrounding code, decomposes the diff into findings, and evaluates each reducible finding against one strictly delineated engine. Not every changed hunk needs a recommendation.
