strings.Contains(stderrStr, "tools from playwright") is too broad and can match failure logs. internal/server/unified.go emits e.g. "Warning: failed to register tools from %s", which still contains the substring "tools from playwright"; in that scenario this test would pass even though no tools were registered.

Instead, assert on a success-only message such as the log.Printf("Registered %d tools from %s: ...") prefix (e.g. match "Registered " + " tools from playwright"), or rely solely on a specific "Registered tool: playwright-browser_close" entry.

Suggested change
if !strings.Contains(stderrStr, "tools from playwright") &&
if !(strings.Contains(stderrStr, "Registered ") && strings.Contains(stderrStr, " tools from playwright")) &&
