3 capabilities in this set.

Part of 3 available through Agent A/B Test Calculator.

  1. 01 Capability

    Analyze variant performance

    Calculates p-values and confidence intervals to see if agent variants differ significantly. It includes corrections for testing multiple versions at once.

  2. 02 Capability

    Calculate bayesian probability

    Uses Beta distributions to find the probability that one agent version outperforms another. It gives you a direct likelihood of success.

  3. 03 Capability

    Estimate test requirements

    Determines the necessary sample size and expected duration for an experiment. It helps you plan how long to run a test before you start.

Before you connect

Questions about Agent A/B Test Calculator.

The practical details behind the request, access and result.

How can I use the Agent A/B Test Calculator to improve my agent's conversion rate?

You can use it to run controlled experiments on different agent prompts or workflows. By comparing the success rates of two versions, you can mathematically prove which one actually drives more conversions.

Can the Agent A/B Test Calculator help me plan my next experiment?

Yes. You can tell your agent how many daily interactions you have and what kind of improvement you want to detect, and it will tell you exactly how many samples you need and how many days the test will take.

Is the Agent A/B Test Calculator suitable for testing multiple agent versions at once?

Absolutely. It includes the necessary statistical corrections to ensure that when you test multiple variants simultaneously, you don't accidentally identify a false winner.

How does the Agent A/B Test Calculator handle uncertainty in small datasets?

It uses rigorous statistical methods like p-values and Bayesian probability to quantify uncertainty, helping you understand if a small sample size is enough to trust the results.

Can I use the Agent A/B Test Calculator with any AI client?

Yes, as long as your client is MCP-compatible, such as Claude, Cursor, or Windsurf, you can use these statistical capabilities directly in your workflow.

How do I know if my agent's performance improvement is real?

You can use the analyze_variant_performance capability. It calculates the p-value to determine if the observed difference in conversion rates is statistically significant or likely due to chance.

Can I plan how long an experiment should run?

Yes, the estimate_test_requirements capability calculates the required sample size and the estimated number of days needed to complete a test based on your daily traffic and desired sensitivity.

What is the difference between the frequentist and Bayesian approaches provided?

The frequentist approach (via analyze_variant_performance) focuses on p-values and significance thresholds, while the Bayesian approach (via calculate_bayesian_probability) provides the direct probability that one variant is better than another.
