donner-pixel-diff

donner-pixel-diff is a Test authoring & frameworks skill for AI agents, published by jwmcglynn in the donner repository on GitHub. Skillspace rates donner-pixel-diff D (55/100) and it passed the safety scan; the rating is based on static analysis only.

Author, triage, and update bitmap/golden-image comparisons in Donner using the one blessed comparator (bitmap_golden_compare / ImageComparisonTestFixture + pixelmatch), read diff PNGs, and regenerate goldens safely. Use when a golden-image or pixel-diff test fails (output mentions "pixels differ", actual_*.png / diff_*.png, or UPDATE_GOLDEN_IMAGES_DIR), when writing any new bitmap comparison (editor replay, layer thumbnails, renderer goldens), or when regenerating goldens after an intentional rendering change.
