Description

Compares visual diffs or screenshots to render a pass/fail verdict. Accepts before/after image paths or URLs, runs a pixel-level diff, and produces a structured verdict with diff percentage, bounding boxes of changed regions, and a human-readable summary.

Interface

interface SkillInput { trigger: string; args: string[]; }
interface SkillOutput { status: "ok" | "error"; message: string; }
export async function activate(input: SkillInput): Promise<SkillOutput>
export function deactivate(): void

Implementation

Extension-only skill. Triggers visual diff comparison in Copilot. The CLI prints guidance directing users to the Copilot CLI slash command.

P3 scope: Integration with Playwright screenshot capture and CI diff reporting (as specified in SPEC-omp-2.0 §5) are deferred to P3. The current implementation accepts user-supplied image paths only.
