visual-regression skillA

visual-regression is agent-read markdown (skill) from hsuanyulee/polaris: Standalone visual regression guard using before/after screenshot comparison. Two modes: SIT (compare staging vs local dev) or Local (compare git-stashed base vs current changes). No long-lived baselines — captures fresh screenshots each run and deletes after comparison. Config-driven from workspace-config.yaml. Use when: "跑 visual regression", "檢查畫面", "頁面有沒有壞", "visual test", "screenshot test", "畫面測試", "截圖比對", "有沒有跑版", "畫面壞了嗎", "UI 有沒有問題", "check if pages look right", for standalone manual inves.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add hsuanyulee/polaris/visual-regression@git:20260824.e610d9d
Exact content
mdr add hsuanyulee/polaris/visual-regression@sha256:c92a20d6f88ccd94

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
