Growthbook agent skills for Claude Code, Cursor and RevampKey

4 ready-made playbooks that teach an AI agent how to do real Growthbook work: which tools to call, what to check first, and when to stop and ask you.

Download RevampKey, free I have it: connect Growthbook

Connect Growthbook once and all 4 skills install themselves and stay up to date. Mac, Windows and Linux.

All 4 Growthbook skills

Each skill is one job. You ask in plain words and the agent loads the skill that matches, then follows its steps.

Use GrowthBook through AI safely

Sets the environment, project and access level before any GrowthBook read or change, and asks for your explicit yes before anything is written.

Use it when

You just connected GrowthBook and want to know what the assistant can do
You are about to change a flag or experiment and want the environment checked first
A GrowthBook request returns a permission or rate-limit error

Tools it uses

get_environments
get_projects
search_growthbook_docs
get_feature_flags
list_feature_keys
get_experiments
get_metrics
get_attributes
get_sdk_connections
create_feature_flag
create_force_rule
create_sdk_connection
create_experiment
set_user_defaults
clear_user_defaults
generate_flag_types

Example

Before we touch anything, which GrowthBook environment and project are we working in, and what can this connection change?

We're in the production environment of the checkout project, with read-only access. I can list the 42 flags and show their status, but nothing changes until you approve it. Want me to start with the flags that have had no evaluations recently?

Read-only3 Growthbook tools

Read out a GrowthBook experiment

Reads out a running or finished GrowthBook experiment, checks whether sample size, duration and metric setup make the result trustworthy, and recommends ship, iterate, stop or keep running. It is read-only and never changes the experiment.

Use it when

A test has been running for a few weeks and someone asks if we have a winner
The dashboard shows a green result and you want to know whether to trust it
You need a clear ship or stop call with guardrails checked

Tools it uses

get_experiments
get_projects
get_environments

Example

Read out the checkout-pricing-v2 experiment. Should we ship the winner?

The checkout-pricing-v2 test has run 9 days with about 4,200 users per variation, short of the 2 full weeks planned, so the result is not yet trustworthy. The split is close to 50/50 as configured. Conversion is up about 0.6 percentage points on the primary metric, but the interval still spans zero. Guardrail error rate is flat. Recommendation: keep running until day 14, then decide.

Read-only7 Growthbook tools

Clean up stale GrowthBook feature flags with AI

Finds stale feature flags, sorts them into remove, keep and needs-a-human, and checks dependencies before proposing anything. It reads first and waits for your approval before changing a flag.

Use it when

Your flag list is long and you want to know which flags are safe to remove
You are not sure whether a flag still gates live traffic or an experiment
You want a reviewed cleanup list rather than a bulk delete

Tools it uses

get_environments
get_projects
get_stale_feature_flags
get_feature_flags
list_feature_keys
get_experiments
get_sdk_connections

Example

Which feature flags in production are stale, and which of them can I safely remove?

I found 23 stale flags in production. 9 look like remove candidates: fully on for over 6 months, with no running experiment attached. 8 should be kept or re-dated because they act as kill switches that have never been flipped. 6 need a human, because I cannot tell from GrowthBook whether the code still reads them. Before removing any of the 9, search the repository for each key. Nothing has been changed yet; tell me which ones to proceed with.

Asks before writing10 Growthbook tools

Set up a feature flag for a safe rollout

Plans a new GrowthBook feature flag for a safe launch: checks the environment and SDK connection, picks the type and a fail-closed default, drafts any targeting, and stages the change for review. It asks before creating or publishing anything.

Use it when

You are adding a new feature behind a flag and want it safe to launch.
You need to target a flag to internal users or a percentage of users.
A flag exists but nothing reads it and you want to find out why.

Tools it uses

get_environments
get_projects
get_sdk_connections
create_sdk_connection
list_feature_keys
get_feature_flags
generate_flag_types
get_attributes
create_feature_flag
create_force_rule

Example

Set up a boolean flag called new-checkout-flow in staging, off by default, and turn it on for our internal team first.

Staging has an SDK connection for the web app, so the flag will reach it. I checked the key: no collision. Proposed: boolean, default false, plus one force rule on the internal-staff attribute set to true. The attribute exists and the SDK sends it. Rollout: internal, then 10%, then everyone. I have drafted these but not published anything. Confirm and I will create the flag and rule as drafts for review.

How Growthbook skills work

Connect Growthbook
The Growthbook MCP server gives the agent its tools.
Ask in plain words
“Read out the checkout-pricing-v2 experiment. Should we ship the winner?” Each SKILL.md says when it applies, so only the one that fits is loaded.
Approve any change
The agent calls the tools in order, checks its work, and shows you any change before it makes it.

How to install Growthbook skills

In RevampKey the skills install themselves when you connect Growthbook. In other tools each skill is one folder with a SKILL.md file, and you also need the Growthbook MCP server connected there.

Growthbook skills FAQ

What is a Growthbook agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Growthbook skill describes one job, which Growthbook tools to use in which order, what to check first and when to stop and ask you.

Do the Growthbook skills change anything on their own?

2 of the 4 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Growthbook.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Growthbook; elsewhere you copy the folders into your project or skills directory.

Do I need the Growthbook MCP server too?

Yes. The skills tell the agent how to do the work; the Growthbook MCP server gives it the tools to do it. The Growthbook MCP setup guide covers every client.
