Research focus

The built-in playwright tool for browser automation and visual verification in agentic workflows — the tools: playwright: frontmatter key, browsers/version pinning, the playwright network ecosystem, and driving the CLI loop (open, snapshot, click/fill, screenshot) via playwright-cli.

Gap identified

Steps 1–29 cover frontmatter, safe-outputs, MCP tools, memory, sub-agents, evals, orchestration, and skills, but no step teaches the agent to look at a rendered page. The playwright tool is a first-class, compiler-provisioned capability (browsers pinned automatically, no manual npx playwright install) that closes this gap by letting an agent verify that a live web surface actually renders/behaves as intended, instead of relying on text-only output.

Files updated

• workshop/30-browser-automation-with-playwright.md (new node): "Verify Your Agent's Work with Browser Automation" — adds the tools: playwright: block, the playwright network ecosystem, and a playwright-cli open → snapshot → screenshot verification exercise, with a ## :white_check_mark: Checkpoint checklist.
• workshop/README.md: added the new node as row 30 in the Part 2 curriculum table.
• workshop/00-welcome.md: no change needed (file does not reference an explicit step count).

XML comment metadata

Stored at the top of workshop/30-browser-automation-with-playwright.md in a <research-metadata> block containing <focus>, <sources>, and <rationale> elements, following the same pattern used in steps 27 and 29.
