3.5Why This Matters for Test Automation

A typical test automation session involves:

• Reading test specifications
• Writing test code
• Running browser interactions
• Analyzing results
• Debugging failures
• Generating reports

If browser interactions consume 50-100% of your context budget (MCP approach), the agent can't effectively do the other tasks. It starts "forgetting" earlier parts of the conversation as the context compresses.

With the skill approach, browser interactions consume ~2% of the context budget, leaving the agent free to:

• Hold an entire test suite in context
• Reason about multi-page flows
• Compare expected vs actual results with full detail
• Maintain conversation history across long sessions
