launchdarkly — Claude Code plugin: what it does, how to install
Connects LaunchDarkly flag workflows and AgentControl configurations directly to your Claude Code workspace.
/plugin marketplace add anthropics/claude-plugins-community
/plugin install launchdarkly@claude-communityWhat launchdarkly does
This plugin bundles modular skills and an MCP server to manage LaunchDarkly resources from the CLI. The agent can examine a pull request diff to check if a code change needs a feature toggle. It also crafts new flags following your existing code patterns and removes obsolete branches when flags retire.
It handles guarded rollouts with rollback mechanisms and detects drift between SDK fallback defaults and remote rules. Another dedicated set of playbooks handles AgentControl migrations, helping you extract hardcoded LLM prompts into versioned configs. The plugin modifies flags directly.
Without an API access token, the MCP server will fail to authenticate and cannot apply updates to your account.
What it helps with
- audit code to identify and remove obsolete feature flags
- evaluate pull request changes to decide if a toggle is required
- set up guarded rollouts with automatic metric-based rollback
- extract hardcoded prompts into managed AgentControl configs
Example prompts for the agent
- /launchdarkly:launchdarkly-flag-cleanup remove the old-checkout flag across the codebase
- /launchdarkly:should-flag-change inspect the current diff and check if it needs a flag
- /launchdarkly:launchdarkly-guarded-rollout roll out redesign-v2 to 25% of traffic
