migrate-gitlab-flags
Migrates a codebase from GitLab Feature Flags (the Unleash-compatible legacy API authenticated with UNLEASH-INSTANCEID) to a modern Unleash v8 server. Inventories flags and strategies, maps GitLab constructs to Unleash equivalents, provisions flags via multiple mechanisms (Unleash MCP server, import files, or direct Admin API), rewrites SDK configuration with minimal code changes, and verifies behavior parity. Use when asked to migrate off GitLab feature flags, move flags to Unleash, or port GitLab flag definitions to an Unleash server.
Install
With your agent
Install OMGSkills skill "unleash/unleash-claude-skills:skills/migrate-gitlab-flags" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/Unleash/unleash-claude-skills /tmp/unleash-claude-skills && ln -s /tmp/unleash-claude-skills/skills/migrate-gitlab-flags ~/.claude/skills/migrate-gitlab-flagsFrom README
Migrate GitLab Feature Flags to Unleash (v8+) Migrate one app or service off GitLab's Unleash-compatible legacy flag API onto a real Unleash v8 server: recreate the flag definitions, rewrite the SDK wiring, and prove behavior parity. There is no automated import/export mechanism from GitLab to Unleash, therefore recreating definitions is always part of the job. Non-negotiable invariants State carries over exactly. A flag enabled in GitLab is enabled in Unleash; a disabled flag arrives disabled (per environment). Always — never ship flags "off for safety" or "on for convenience". Flag names are unchanged (the only exception: a collision prefix agreed with the user when sharing an OSS default project — see Inputs step 3). Minimal code diff. Mirror the existing patterns; the migration is not a refactoring opportunity (see Phase 5). Least-privilege credentials.
