Reproduce Design editor issues

Use this skill for defects that need a real Design editor session. Work from a local or production copy of an Agent-Native design and describe the observed application behavior directly.

Setup

1. Start the worktree's Design app with .agents/skills/design-editor-repro/harness/start-dev.sh.
2. Run node .agents/skills/design-editor-repro/harness/doctor.mjs until the local app and editor session are ready.
3. Copy a source design with node .agents/skills/design-editor-repro/scripts/copy-design.mjs . Use a production copy only when DESIGN_TEST_EMAIL and DESIGN_TEST_PASSWORD are configured. Remove that copy when finished.
4. Reproduce the reported steps before changing application code. Save only task-relevant files under templates/design/.tmp/editor-repro/.
