How We Made AI Test Generation 9× Faster and 6.7× Cheaper

How we replaced our multi-agent test generator with a single long-context agent that explores apps through the Playwright MCP. Deterministic steps like running tests moved to a Python service. On our internal benchmark, the new generator was 9× faster and 6.7× cheaper per test.
