feature-flag-onboarding

Orchestrate first-time Harness FME onboarding for one application. Confirm an already-enabled FME account/project, then pick one verified non-production environment; if none exists, hand off to an admin, not creating one. Detect the codebase's language and framework, then delegate code integration to instrument-feature-flag — never duplicating its wrapper design or creating the same flag twice. Verify two distinct named-treatment outcomes live through separately approved targeting changes when needed, not just default/fallback responses. Resumes from live state and a non-secret progress summary instead of a checkpoint file; never recreates a flag from uncertain absence or reuses a stale approval. Use when asked to onboard FME for an app, set up feature flags end-to-end, or prove a flag works live. Not for flag creation alone (create-feature-flag), code gating alone (instrument-feature-flag), targeting alone (update-flag-targeting), or metric/experiment setup.

# Feature Flag Onboarding

Orchestrate a new application's first end-to-end FME setup: confirm scope, pick a safe environment, detect the codebase, delegate code integration, then prove two distinct treatments actually run live. This skill sequences and verifies; it does not re-implement flag creation, code wiring, or targeting changes — those live in `/create-feature-flag`, `/instrument-feature-flag`, and `/update-flag-targeting`.

## Tools

Works through the Harness MCP server or the Harness CLI; names are from [tool-map.md](../../../references/fme/tool-map.md). All writes are delegated to the linked skills — this skill only reads.

| Operation | MCP | CLI |
|-----------|-----|-----|
| List environments | `harness_list` · `fme_environment` · `compact: false` | `harness list fme_environment --json` |
| List flags | `harness_list` · `fme_feature_flag` · `size: 50` · `compact: false` | `harness list feature_flag --json --limit 50` |
| Get flag | `harness_get` · `fme_feature_flag` · `params.feature_flag_name` | `harness get feature_flag <name> --json` |
| Get definition | `harness_get` · `fme_feature_flag_definition` · `params: { feature_flag_name, environment_id }` | `harness get feature_flag:definition <flag> --env <env-id> --json` |
