What is experiment-analyze?

Fetch results for a GrowthBook experiment, refresh the snapshot only when the cached data is over 24 hours old, then interpret. Use when the user asks "what are the results of X", "analyze this experiment", "is X winning", "did the test work", "show me the results", or "dig into the dimensions". Reads only — does not stop or modify the experiment. For stopping after you've seen results, use experiment-stop.

experiment-analyze

Fetch results, refresh the snapshot only when the cached data is over 24 hours old or the user wants a different phase/dimension cut, then interpret. This skill is the heaviest in the catalog because of the conditional polling loop and the statistical interpretation — slow down and do each step deliberately.

All API calls go through the bundled helper: ${CLAUDE_PLUGIN_ROOT}/scripts/gb-call. It needs GB_API_KEY — set in your shell, or written to ~/.config/growthbook/.env by /growthbook:gb-setup. If unset or invalid, gb-call's error message points back at /growthbook:gb-setup. The skill also uses sleep between poll calls.

Workflow

  1. Fetch results + experiment metadata in one call. /results returns { experiment, result } — the same payload that powers the GrowthBook UI's results view, so there's no need for a separate metadata call.

    gb-call GET /api/v1/experiments/<experiment-id>/results
# or, when the user asks for a specific phase / dimension cut:
gb-call GET '/api/v1/experiments/<experiment-id>/results?phase=1&dimension=exp:country'
