A frontend review and implementation guide for design consistency, accessibility, responsive layouts, component states, themes, and reusable design values.

Use it to audit or build interfaces across frontend frameworks, including checks for design tokens, accessibility, responsive behavior, and theming.

It helps find problems such as hardcoded colors, inconsistent spacing, missing keyboard focus states, poor contrast, and broken dark mode.

ds-frontend — Skill for Claude Code and Codex by sungurerdim

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add sungurerdim/dev-skills --skill ds-frontend

Clone the repo

git clone --depth 1 https://github.com/sungurerdim/dev-skills

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.05802
Opus 5.5	$0.00017	$0.02321
Sonnet 5.5	$0.00009	$0.01160
Haiku 4.5	$0.00004	$0.00580

Security

Grade A, and why

ds-frontend scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ds-frontend

Hardcoded colors, inconsistent spacing, missing focus states, broken dark mode — design systems exist to prevent these. This skill enforces them in code.

Frontend Design Quality — design system audit, token enforcement, component states, accessibility, responsive layout, theming.

Completion Evidence — applies to every phase: Report done/OK only with the machine-checkable evidence the gates name — the exact command run and its observed output (or file:line diff). Missing evidence → report INCOMPLETE plus what is missing. Self-assessment is never evidence. (This band repeats at file end by design — both copies are normative.)

Triggers

User runs /ds-frontend, or asks to audit UI/design-system/components/a11y/WCAG/contrast/dark-mode/responsive/tokens, or create a design system; or the project contains frontend framework indicators (React, Vue, Svelte, Astro, SolidJS, htmx, Angular, Flutter, RN, SwiftUI, Compose).

Triggers — INVOKE / DON'T INVOKE

INVOKE	DON'T INVOKE
"audit design system / tokens / hardcoded colors"	"audit business logic" (→ ds-review)
"WCAG / a11y technical audit (contrast, focus, ARIA)"	"regulatory a11y framing (EAA, ADA)" (→ ds-compliance --a11y)
"generate design tokens / set up theming"	"mobile gestures, permissions, store" (→ ds-mobile)
"review component states (empty/loading/error)"	"fix type errors in components" (→ ds-fix)
"audit stale/stub routes, dead or mismatched buttons"	"chart/dataviz color palette selection" (→ dataviz)

Contract

Dimensions: A5 (ux scope), A6 (UI), A7 (implementation), A9 (conditional ecosystem rules), D10 (admin UI)

Audits UI/UX quality across web, mobile, desktop UI — only touches UI-layer code (styles, components, tokens, ARIA); business + backend untouched.
Privacy/PII data-handling audit is out of scope: /ds-compliance present → advisory-handoff; absent → gap-note [privacy] not analyzed — requires /ds-compliance. Never runs its own privacy detector.
Standalone. Uses blueprint profile or ds/audit/findings.md when available; own analysis when absent.
State-qualifying: scope-by-scope progress exists nowhere else — an interrupted run would re-scan from zero without it. Persists to ds/audit/frontend.json with the run's git_hash; applied fixes land in the working tree, git is the durable record. Deleted when the Summary completes.
Full accounting enforced: every finding and planned check ends in an explicit disposition (fixed / skipped + reason / only you can do); summary totals balance.
Pre-existing / out-of-scope errors detected during work are NOT skipped — fixed inline or escalated with concrete blocker.

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ds-frontend is a skill published in the GitHub repository sungurerdim/dev-skills (1 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 5,802 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
