Playwright, MCP and nine years of testing the systems I build. I owned quality for an ERP, a CRM, a B2B panel and a warehouse app, and I now bring that to AI-assisted development.
Notes on testing, agents and shipping alone.
Agentic QAI ran Playwright's three test agents against this live site. The Planner found a real bug, the Generator wrote a test that encodes it, and the Healer showed why every heal needs a human review.
AI ToolingAlmost every agent failure I hit this year was a harness problem, not a model problem. What a harness is, what LangChain gained by changing only the harness, and three failures from building this site.
TestingAI agents now write, run and repair a growing share of our tests. At the base of the pyramid they make it stronger. At the top they can rebuild the ice-cream cone faster than any team ever could.
One email when something ships or something breaks interestingly. Nothing else.
