Perkcord UI Visuals

Perkcord UI Visuals Skill

Purpose: make UI changes safely with a deterministic visual verification loop.

When To Use

• You changed anything user-facing in apps/web (copy, layout, component styling, subscribe/admin flows).
• You updated branding/theming, tier rendering, checkout UI, or admin dashboards.

Guardrails

• Treat visual snapshots as a contract: update them only when the change is intentional.
• Prefer stable test data (seeded) and stable page states (wait for navigation/data before screenshot).
• If a snapshot changes unexpectedly, investigate before updating.

Commands

Core web checks:

npm --prefix apps/web run lint
npm --prefix apps/web run typecheck
npm --prefix apps/web run test

Playwright visuals:

PLAYWRIGHT_TEST_PORT=3002 npm --prefix apps/web run test:e2e:visual

If snapshots must be updated intentionally:

PLAYWRIGHT_TEST_PORT=3002 npm --prefix apps/web run test:e2e:visual:update

If you need Linux-rendered Playwright baselines locally:

bash scripts/update-linux-snapshots.sh --playwright-only

Storybook snapshots:

npm --prefix apps/web run test:storybook

If Storybook snapshots must be updated intentionally:

npm --prefix apps/web run test:storybook:update

Snapshot Locations

• Playwright: apps/web/e2e/*.spec.ts-snapshots/
• Storybook: apps/web/storybook-snapshots/

Notes:

• CI runs on Linux, so snapshot baselines are platform-specific.
  • Playwright snapshots include the OS in the filename (e.g. *-chromium-linux.png).
  • Storybook snapshots include the platform suffix (e.g. *-linux.png, *-win32.png).

Troubleshooting Notes

• If Playwright hangs or ports are busy, check 3210/3211 (Convex) and 3001/3002 (Next).
• If admin pages show Unauthorized. or API key not configured., check PERKCORD_REST_API_KEY in both Vercel and Convex.
• On Windows, if Linux snapshot refresh fails because Docker is not running, start Docker Desktop first (for example via PowerShell Start-Process "$Env:ProgramFiles\Docker\Docker\Docker Desktop.exe") and rerun bash scripts/update-linux-snapshots.sh --playwright-only.
• Local Playwright runs now auto-strip repo-root cloud Convex keys before booting local Convex; if a run still targets cloud unexpectedly, inspect repo-root .env.local, apps/web/.env.local, and convex/.env.local for conflicting overrides.
• If Storybook output looks unstyled, confirm Tailwind is applied (PostCSS pipeline in apps/web/.storybook/main.ts).

Human Review (VLM)

When snapshots change:

• Review the PNG diffs with a VLM before declaring the work done.
• Record the intent in the PR description: what changed and why.
