Confidence AI Plugin

Official Confidence plugin for AI coding tools. Manage feature flags, experiments, onboarding, and migrations right from your agent.

✨ Highlights

• Manage feature flags without leaving your editor: create, list, update, target, resolve, and archive flags from Claude Code, Cursor, Codex, or Gemini CLI
• One-command migrations from PostHog, Eppo, Statsig, or Optimizely, covering flags and SDK code
• Guided onboarding: spin up a Confidence account, invite teammates, create SDK clients, and connect a warehouse without reading a setup doc
• Docs on tap: search Confidence documentation and SDK integration guides inline while you code
• Works with every major AI coding assistant through the same MCP servers

ℹ️ Overview

Confidence is Spotify's feature flagging and experimentation platform, built on the OpenFeature standard. This plugin exposes Confidence's flag management, documentation, and migration tooling as MCP servers and slash commands, so you can create a flag, plan a migration off another platform, or onboard a new workspace directly from your AI coding assistant's chat.

⬇️ Installation

Claude Code

claude plugin install confidence

Cursor

From the Marketplace: open Cursor Settings → Plugins, search for Confidence, and click Install.

Manual setup: add the MCP servers to .cursor/mcp.json in your project (or ~/.cursor/mcp.json globally):

{
  "mcpServers": {
    "confidence-flags": {
      "url": "https://mcp.confidence.dev/mcp/flags"
    },
    "confidence-docs": {
      "url": "https://mcp.confidence.dev/mcp/docs"
    }
  }
}

Codex

codex plugin marketplace add spotify/confidence-ai-plugins
codex
/plugins
# Select Confidence and install

Gemini CLI

gemini extensions install https://github.com/spotify/confidence-ai-plugins

Local Development

git clone https://github.com/spotify/confidence-ai-plugins.git
claude --plugin-dir ./confidence-ai-plugins

Skills only, any agent

The migration and onboarding skills can also be installed individually via the skills CLI, which supports Claude Code, Cursor, Codex, Gemini CLI, and 70+ other agents:

npx skills add spotify/confidence-ai-plugins

This installs only the skill logic (auto-triggering guidance for migrations and onboarding). It does not configure the confidence-flags/confidence-docs MCP servers or the /confidence:* slash commands, even when targeting one of the four clients above. Since several skills call into those MCP servers to manage flags, use one of the full installs above for complete functionality; use this only if you want the skill guidance on an agent the full installs don't support.

🚀 Usage

Once installed, just ask your assistant:

> List my feature flags
> Create a flag called new-checkout with a boolean schema
> /confidence:onboard-confidence create-account
> /confidence:migrate-posthog plan flag
> /confidence:migrate-posthog plan code
> /confidence:migrate-eppo plan flag
> /confidence:migrate-eppo plan code
> /confidence:migrate-statsig plan flag
> /confidence:migrate-statsig plan code
> /confidence:migrate-optimizely plan flags
> /confidence:migrate-optimizely plan code
