GrowthBook

Manage the full GrowthBook feature flag and experimentation lifecycle without leaving your editor. This plugin provides a comprehensive suite of skills that connect directly to the GrowthBook REST API, covering flag creation, targeting, rollouts, experiment design, dependency auditing, and stale flag cleanup — all through natural-language commands.

The flag management skills handle the complete lifecycle: create flags with collision-safe key validation, toggle environments on or off, configure targeting rules and progressive rollouts with metric guardrails, manage draft revisions and approvals, and safely archive or delete stale flags with automated code-reference inlining. A dependency graph skill traces prerequisites, reverse dependencies, and linked experiments to assess blast radius before changes.

For experimentation, dedicated skills walk you through designing statistically rigorous A/B tests — from hypothesis framing and metric selection to sample-size estimation — then hand off a launchable spec. Discovery skills let you search, filter, and audit your flag inventory, surfacing cleanup candidates based on staleness criteria.

How to use: Start with /growthbook:gb-setup to configure your GrowthBook API credentials. Then try commands like /growthbook:flag-create to create a new feature flag, /growthbook:flag-search to find and audit existing flags, /growthbook:experiment-design to plan an A/B test, /growthbook:flag-graph to visualize flag dependencies, or /growthbook:flag-cleanup to safely remove stale flags.
