Best When
An agent needs to create, manage, or analyze GrowthBook A/B experiments and feature flags — especially integrated with data warehouse metrics.
Avoid When
You're using Optimizely, LaunchDarkly, or another A/B testing platform.
Use Cases
- • Creating and managing A/B experiments from product analytics agents
- • Querying experiment results and statistical significance from analysis agents
- • Managing feature flags for progressive rollouts from deployment agents
- • Querying feature flag states from release management agents
- • Analyzing experiment performance data from data science agents
- • Coordinating product experiments with data warehouse metrics from BI agents
Not For
- • Teams using Optimizely, LaunchDarkly, or Statsig as primary experimentation platform
- • Simple feature flags without experimentation needs (simpler tools exist)
- • Teams without data warehouse connectivity for experiment analysis

Known Gotchas
- ⚠ GrowthBook requires data warehouse integration for statistical analysis — not standalone

- ⚠ Feature flag targeting conditions use GrowthBook's attribute system — must match SDK context
- ⚠ Self-hosted vs Cloud have same API but different base URLs
- ⚠ Experiment phases must be advanced manually or via schedule — not automatic
- ⚠ Organization ID required for all API calls
