What problem does it solve?
Agent-written Playwright tests often use brittle selectors that create flaky CI and expensive debugging for a solo builder.
Who is it for?
Builders shipping SaaS or web apps with Playwright coverage who want the agent to proactively harden locators before tests break in production pipelines.
Skip if: Projects with no browser automation, or teams that only run unit tests without Playwright or similar E2E tooling.
What do I get? / Deliverables
You get scored selector risk, concrete healing ideas, and receipts so E2E specs stay maintainable through UI churn.
- Selector risk assessments for Playwright locators in context
- Healing suggestions aligned to browser automation best practices
- Guard receipts documenting selector decisions for PR or CI notes
Recommended MCP Servers
Journey fit
Selector hardening is part of shipping reliable browser tests, so Ship with testing is the canonical placement. Testing subphase fits because the tools target Playwright locators, healing, and automation stability rather than visual design alone.
How it compares
Playwright-focused selector guard MCP, not a general web scraper or a static analysis skill for backend code.
