description	Guides work on `packages/frontend/editor-ui` experiments. Use when creating, extending, wiring, testing, reviewing, or retiring editor-ui experiments, PostHog feature flags, experiment key indexes, variants, stores/composables, persisted experiment state, or experiment telemetry.

Experiments

Use this skill for frontend experiment code lifecycle work in packages/frontend/editor-ui.

Start with the relevant mode in reference.md:

Create for a new experiment folder, constant, store/composable, and tests.
Extend for new variants, behavior, display logic, or telemetry on an existing experiment.
Wire for host-surface integration through routes, modals, views, or components.
Test for store, composable, persistence, telemetry, and UI behavior coverage.
Review for auditing experiment changes.
Retire for cleaning up completed or abandoned experiments.

When experiment work touches Vue components or user-facing copy, also follow n8n:design-system and n8n:content-design.

workflow-builder

Load before calling build-workflow. Default path for all single-workflow work: new one-off workflows, existing-workflow edits, verification repairs, and workflow-local data tables. Write or edit a workspace source file, run workflow-sdk validate via workspace_execute_command, then call build-workflow with filePath. When the workflow creates or writes Data Tables, load data-table-manager first, then this skill. Do not load planning or create-tasks first. Load planning only when multiple coordinated workflows or shared cross-task data tables require a dependency-aware task graph.

n8n-create-instance-ai-eval

Authors a new Instance AI workflow eval case — written locally as JSON, calibrated against a real build, then pushed to the LangTracer suite CI runs — build cases, behaviour/process cases, credential cases, and seeded (mid-conversation) cases — with intent-driven expectations. Use when adding or changing an Instance AI workflow eval, or debugging why one is flaky.

agent-builder

Load before calling build-agent for a new or existing n8n Agent. Governs prerequisite creation, faithful handoff of the user's request, agent targeting across turns, builder questions, testing, and publishing. Use directly for routine follow-ups when the conversation already targets an Agent; rerun intent-recognition only when the requested artifact is no longer clear.
