improve-codebase-architecture SKILL.md skillA

improve-codebase-architecture from aethrox/doctrine is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add aethrox/doctrine/improve-codebase-architecture@git:20260911.a358ed0

Pins git:20260911.a358ed0 in mdr.lock. Pin the fingerprint instead.

Scan a codebase (or a named area of one) for architectural friction, classify each finding by how it was incurred, and propose deepening opportunities in priority order. Use when the user wants an architecture review, asks where the design is causing pain, wants technical debt surfaced and prioritized, or asks what to refactor next.

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 Codebase Architecture

Not every rough edge is the same kind of problem. This skill's defining constraint, from Martin Fowler's technical debt quadrant: every finding is classified on two axes before it's prioritized: **deliberate vs. inadvertent** (was the tradeoff known at the time) and **prudent vs. reckless** (was it a reasoned tradeoff or a corner cut under pressure). A knowingly-accepted tradeoff and an accidental mistake call for different responses even when the resulting code looks identical.

This skill finds *what's shallow*; `codebase-design` supplies the vocabulary (module, interface, depth, seam) for describing *why*, and the deletion test in Phase 2 is this skill's own. Use that skill's terms exactly rather than drifting into generic words like "component" or "service."

## Phase 1: Scope the scan

Decide where to look before looking everywhere, scanning a whole codebase uniformly dilutes attention across places that don't need it:

- If the user named a module, subsystem, or pain point, take it directly.

How to install

The exact contents, by fingerprint

mdr add aethrox/doctrine/improve-codebase-architecture@sha256:94df7aa1679658e2

The line at the top of this page pins the label git:20260911.a358ed0, 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.
