Apply it when the work is about how the\ninterface *looks and feels*, not just how it's wired.\n\n## Responsive & performance\n- Works across the target screen/device matrix (responsive/adaptive).\n- Unnecessary renders (memo/callback), bundle size, lazy loading, virtualization for long lists.\n\n## Verify at runtime (contract)\nProve a change works by **observing the running UI**, structured — not by interpreting a screenshot. Have components\nemit `data-verify-*` state attributes, register verifiable units with fixtures + invariants (≥1 adversarial `probe`\neach), expose `window.__verify`, and adopt the `PASS/FAIL/BLOCKED/SKIP` taxonomy (when in doubt, FAIL). Then drive\nthe browser to check it. The full convention: **`references/verify-contract.md`**.\n\n## DoD (this skill's contribution)\n- `/simplify`; no dead styles/unused props.\n- The four states are covered; `i18n-integrity` clean; accessibility passes the baseline matrix.\n- `review-agent-csk` clean.\n\n## Constraints\n- Surgical change; follow existing conventions, do not impose a stack/preference.\n- Do not present data the platform does not provide as if it existed; do not promise a capability that isn't there.\n- §4 applies: no AI trace or vendor template name in code/comments/strings.\n","tagline":"Stack-agnostic frontend discipline (web · mobile · desktop): component structure, state, data fetching,\nloading/empty/error states, i18n, accessibility, performance. frontend-expert-csk applies it on every stack.","category":"data-analysis","tags":["agent-skill"],"author":"byerlikaya","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"byerlikaya/claude-starter-kit","creatorName":"byerlikaya","creatorUrl":"https://github.com/byerlikaya","sourceUrl":"https://github.com/byerlikaya/claude-starter-kit/tree/main/claude-starter/skills/frontend","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/byerlikaya-frontend#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
