improve-code-quality SKILL.md skillA

This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.

improve-code-quality from wondelai/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add wondelai/skills/improve-code-quality@v1.0.2

Pins v1.0.2 in mdr.lock. Pin the fingerprint instead.

Guided journey from a working-but-untested vibe-coded prototype to a production-ready product with tests, clean structure, a business-rules boundary, and resilience at scale. Orchestrates nine skills phase by phase - working-with-legacy-code, clean-code, refactoring-patterns, software-design-philosophy, clean-architecture, pragmatic-programmer, release-it, system-design, ddia-systems - asking the user questions at every decision point and recording results in the project docs/ folder…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Improve Code Quality

Turn a working-but-untested vibe-coded prototype into a product you can ship and operate. This is an
interactive, resumable journey of nine 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. A
week-old prototype is already legacy code — so the first move is a safety net, and every phase after
it is verifiable because of that net.

## Core Principle

**A week-old untested prototype is already legacy code: flip tactical to strategic — safety net
first, then readability, structure, and production hardening in order.** 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. Skipping ahead (refactoring
before tests, scaling before sizing) is the exact failure mode this ordering exists to prevent.

## Journey Map

| Phase | Skill | Question it answers | Artifact |
|---|---|---|---|
| 1 | working-with-legacy-code | Can I change this code without breaking it unknowingly? | Creates docs/TESTING.md + docs/TECH-DEBT.md — GATE |

How to install

The exact contents, by fingerprint
mdr add wondelai/skills/improve-code-quality@sha256:bb4ec46eadb0e1aa

The line at the top of this page pins the label v1.0.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
