docs: add guide for taking website screenshots with Playwright

[Copilot]

• Create docs/src/content/docs/guides/playwright-screenshots.md guide
• Add the new guide to the sidebar in docs/astro.config.mjs
• Updated examples to use localhost (not example.com)
• Removed allowed_domains from Playwright config (localhost is default)
• Aligned guide with real workflows (daily-multi-device-docs-tester, test-copilot-playwright-screenshots):
  • Removed network: block from localhost examples (not needed)
  • Updated screenshot path to /tmp/gh-aw/ convention
  • Fixed bash allowlist patterns to "npm *", "mkdir *" etc.
  • Added kill *, sleep *, curl * to bash allowlist
• Build docs to verify no errors and all links are valid

Original prompt

Write a guide on how to upload assets and create issues to prompt a workflow to take website screenshots using Playwright, and post the results in issues.

The guide explains that you must first take the screenshots, then upload them as assets. After that, you use the asset URL returned by the upload step in the issue body.

Configure the firewall to allow access to the server if it is not running locally. If you are testing a local server in a build, this should work without additional configuration.

@copilot is localhost, not example.com

Remove allowed domains onnplaywritj.

[Copilot]

Fixed in c8f1f9a. All examples now target http://localhost:4321 and playwright: is declared without allowed_domains (localhost is allowed by default). The Network Configuration section still explains how to add external domains when needed.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• telemetry.astro.build
  • Triggering command: /opt/hostedtoolcache/node/24.13.0/x64/bin/node node /home/REDACTED/work/gh-aw/gh-aw/docs/node_modules/.bin/astro build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot compare guide to existing agentic workflows that use playwright and upload assets like multi device tester

@copilot compare guide to existing agentic workflows that use playwright and upload assets like multi device tester

Compared the guide against daily-multi-device-docs-tester.md and test-copilot-playwright-screenshots.md. Updated in bb05169:

• Removed the network: block from localhost examples — the real workflows (test-copilot-playwright-screenshots, test-claude-playwright-screenshots) have no network: block at all for localhost
• Changed screenshot path to /tmp/gh-aw/ (convention used in all real workflows)
• Fixed bash allowlist patterns to "npm *", "mkdir *" (space before *) and added "kill *", "sleep *", "curl *" matching the real workflow patterns
