Playwright Edge Preference

Playwright Edge Preference

Use this skill when browser tasks must run in Microsoft Edge.

Workflow

1. Confirm Microsoft Edge is installed on the host.
2. Run Playwright automation with channel="msedge" as default.
3. Keep runs deterministic (bounded scripts, explicit output paths).
4. Fail closed if Edge is unavailable; do not silently switch browsers.

Scope Boundary

Use this skill for Edge-channel browser execution and parity checks.

Do not use this skill for:

1. Non-browser repo operations.
2. General skill routing decisions.
3. Asset-heavy browser workflows that bypass no-churn controls.

Edge Availability Check (PowerShell)

$edgeCandidates = @(
  "$env:ProgramFiles(x86)\Microsoft\Edge\Application\msedge.exe",
  "$env:ProgramFiles\Microsoft\Edge\Application\msedge.exe"
)
$edgePath = $edgeCandidates | Where-Object { Test-Path $_ } | Select-Object -First 1
if (-not $edgePath) { throw "Microsoft Edge not found on this host." }
$edgePath

Edge Run Patterns

Node one-shot (headless screenshot):

node -e "const { chromium } = require('playwright'); (async () => { const browser = await chromium.launch({ channel: 'msedge', headless: true }); const page = await browser.newPage(); await page.goto('https://example.com', { waitUntil: 'domcontentloaded' }); await page.screenshot({ path: 'edge-shot.png', fullPage: true }); await browser.close(); })();"

Playwright test project pattern:

npx playwright test --project=edge

Integration Notes

• Pair with playwright-safe when churn sensitivity is high.
• Use skill-hub first if lane selection is still ambiguous.

Loopback

If this lane is unresolved, blocked, or ambiguous:

1. Capture current evidence and failure context.
2. Route back through $skill-hub for chain recalculation.
3. Resume only after the updated chain returns a deterministic next step.
