What is experiment-brainstorm?

Propose new experiment ideas grounded in the team's past stopped experiments via the GrowthBook REST API. Use when the user asks "what should we test next", "give me experiment ideas", "brainstorm A/B tests", "what's worth testing", or "ideas for experiments". Proposes only — does not create experiments. For designing a specific test, use experiment-design. For reading results of one, use experiment-analyze.

experiment-brainstorm

Propose new experiment ideas grounded in the team's past stopped experiments. Read history first; propose based on what actually moved metrics, where guardrails failed, and which tags or projects under-explored.

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.

Workflow

  1. Pull the experiment list, most recent first.

    gb-call GET '/api/v1/experiments?limit=50&status=stopped'
    

    Returns up to 50 experiments per page (the API cap).

  2. Fetch results for each stopped experiment. Loop over the stopped IDs:
