Triaging visual review runs

Visual Review is PostHog's screenshot-regression product: CI captures storybook + playwright screenshots, diffs them against committed baseline hashes, and gates the PR until a human approves the visible changes. A PR with visual changes carries a visual-review GitHub status check that stays red until each diffed snapshot is approved or tolerated in the VR UI.

This skill teaches an agent how to answer the questions a human reviewer would actually ask, by chaining the read-only VR MCP tools — instead of reaching for gh pr view and tab-hopping to the VR web UI.

When this skill applies

Trigger this skill on any of:

• A PR number, branch name, or commit SHA paired with words like visual review, VR, snapshot, screenshot, storybook diff, playwright snapshot, baseline, approve, tolerated, quarantine.
• Questions about why a PR is blocked, what visually changed, or whether a diff is real.
• "Is my run done?" / "What's left to review?" / "Has this story flaked recently?"
• A failing visual-review GitHub check or a PR comment from the posthog-bot mentioning visual review.
