qa from darknecrocities/skillbuilder is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add darknecrocities/skillbuilder/qa@git:20261025.dc4a5c9

Pins git:20261025.dc4a5c9 in mdr.lock. Pin the fingerprint instead.

Comprehensive Two-Tier Quality Assurance skill. Features Full UI/Frontend QA (viewports, touch ergonomics, WCAG 2.2 AA, sub-pixel lighting, 120Hz compositor) and Full App Functional QA (state machines, real persistence, 3s/15s network resilience, mobile OS lifecycle, memory leaks, security, and Master Error Catalog).

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

# Two-Tier Quality Assurance Engine (`/qa`)

> **Philosophy**: *A feature is incomplete until it passes both tiers of scrutiny: sensory visual perfection across viewports and resilient runtime correctness under real network drops and OS memory pressure.*

This skill establishes the production standard for software verification across Web and Mobile platforms (React, Next.js, Vue, Svelte, React Native, iOS SwiftUI, Android Jetpack Compose, and Flutter).

How to install

The exact contents, by fingerprint

mdr add darknecrocities/skillbuilder/qa@sha256:cc26fae4da3fe2d3

The line at the top of this page pins the label git:20261025.dc4a5c9, 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.
