When to use Web Ui Test

Choose if

You're inside an agent loop and want to drive Playwright MCP through a structured skill that handles registration, snapshotting, clicking, typing, waiting, and console-error checks — without dumping raw snapshot data back into your context. Pick this over calling Playwright MCP tools directly when you want enforced output summarization and a known recovery path for the Chrome profile lock failure mode.

Avoid if

You don't have Node.js + npx available, can't run Chrome with the `mcp-chrome` persistent profile, or you need raw snapshot data rather than summaries (the skill explicitly prohibits returning raw snapshots). Also avoid when concurrent Playwright instances may already hold the `mcp-chrome` profile lock — the README documents this as an immediate-exit failure mode requiring manual recovery.

Risk Flags

  • MEDIUM scope README documents a recurring failure mode where a previous Playwright Chrome process holds the `mcp-chrome` profile lock, causing immediate exit; recovery requires killing processes and deleting lock files or using a timestamped profile.
  • LOW scope README explicitly prohibits returning raw snapshot data — only summaries are permitted, which limits use cases that need the full DOM tree.
  • LOW scope Large pages may exceed practical snapshot size; the README suggests targeted evaluation queries and screenshots as workarounds.
