Launchdarkly Flag Create

This guides Claude through creating LaunchDarkly feature flags that actually match your codebase's existing patterns. It starts by searching for how you already use the SDK, checks naming conventions and wrapper patterns, then creates the flag and adds evaluation code that fits in. The workflow is thorough: explore before creating, pick the right flag type (boolean for toggles, multivariate for experiments), add the code following your team's style, and verify everything compiles. Flags always start disabled for safety. The real value is in Step 1, which prevents the common mistake of introducing flag patterns that clash with what your team already does. Requires the LaunchDarkly MCP server.

LaunchDarkly Flag Create & Configure

You're using a skill that will guide you through introducing a new feature flag into a codebase. Your job is to explore how flags are already used in this codebase, create the flag in LaunchDarkly in a way that fits, add the evaluation code matching existing patterns, and verify everything is wired up correctly.

Prerequisites

This skill requires the remotely hosted LaunchDarkly MCP server to be configured in your environment.

Required MCP tools:

create-flag: create a new feature flag in a project
get-flags: verify the flag was created correctly

Optional MCP tools (enhance workflow):

get-flags: browse existing flags to understand naming conventions and tags
update-flag: update flag metadata (name, description, tags, temporary/permanent status)
