## How to choose

- Answers against known values: Ask a funnel and a retention question whose answer you already know, since a query that returns a plausible number can still count events wrongly.
- Query limits and result size: Check the limits on query rate, result size and time range, since an agent that loops over a large cohort can hit them partway through an analysis.
- Raw event export and retention: Check whether raw events can be exported and how long they are kept, since an agent cannot re-run a question once the events have aged out.
- Experiment results over the API: Check whether experiment results and flag states can be read through the API, since an agent deciding a rollout needs the same numbers the dashboard shows.

- How the benchmark tests this category: One fixed event set loaded into each listing, then the same questions asked through its API or MCP server (a funnel conversion, a retention curve, a cohort size and an experiment result). We check the answers against known values and the limits on queries. In this run listings are graded from public evidence against the published checklist.
