From d0485003f28cd0598e7f69f6fa3585ecfad866fe Mon Sep 17 00:00:00 2001 From: AppHub Developer Date: Mon, 22 Jun 2026 14:06:02 +0300 Subject: [PATCH] feat(agents): frontend-engineer owns design-system; add frontend-test-engineer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes the cross-branch design-system duplication that stranded features (identity #65, i18n #72, billing #81 each independently re-edited design-system/ → merge conflicts → nothing converges). - frontend-engineer is now the SOLE owner of design-system/: derive components from the user story → add missing primitives to the DS FIRST (landed as a foundation; one PR when features run in parallel) → then build the feature UI. - All other agents: never edit design-system/ (consume only) — added to NOT-scope. - New frontend-test-engineer: INDEPENDENT UI verification via Playwright, pre-prod (ephemeral stack, gates merge) AND post-prod (smoke vs live app). Split out from test-engineer, which is now scoped to API/contract/integration/event tests. - README roles + sequence updated (DS foundation step; fe-test after fe-engineer).
