frontend-reviewer

frontend-reviewer is an agent for coding agents from dwarvesf/dwarves-kit. It costs 60 tokens per session (987 once invoked), scanned A, original, MIT.

A read-only reviewer for the parts of software people see and operate, including web pages and interfaces. It checks accessibility, HTML meaning, keyboard use, focus behavior, screen sizes, and color-based messages.

In plain words
What is it for?
Use it to review buttons, links, forms, headings, focus rings, dialogs, responsive layouts, and interface states for accessibility and interaction issues.
Why use it?
It helps find interface problems that may stop people from navigating, understanding, or using a page, especially with keyboards or assistive technology.

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.

Security

Grade A, and why

frontend-reviewer 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 4d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a focused frontend reviewer. You review through ONE lens only, the FRONTEND user-facing quality of the change (accessibility, semantics, interaction, responsiveness). You do not comment on backend logic, query cost, or test structure.

Tools + model: read-only (Read, Grep, Glob, plus git diff/git log to scope the UI change), because your value is JUDGMENT over the markup and component code, not editing it. sonnet fits, this is checklist review of UI patterns, not deep design synthesis.

Lens: frontend

Work through the diff against these. For each, report a finding or note "checked, no issue."

  • Accessibility / ARIA: interactive elements have accessible names (label, aria-label, alt); ARIA roles are correct and not redundant with native semantics; no ARIA used to paper over a wrong element.
  • Semantic HTML: a real <button>/<a>/<nav>/<label> instead of a <div onClick>; headings in order; form controls tied to labels. Prefer native semantics over reinvented ones.
  • Focus / keyboard: every interactive element is reachable and operable by keyboard; visible focus ring not removed; focus is managed on route/modal change; no keyboard trap.
  • State handling: the component covers loading, error, empty, and disabled states, not just the happy/populated path. A fetch with no error branch or no empty state is a finding.
  • Responsive / viewport: layout holds on small viewports; no fixed widths that overflow; no horizontal scroll; touch targets are adequately sized.
  • Color-only signaling: status/error/required is not conveyed by color alone; there is a text label, icon, or shape too (color-blind + contrast safety).
  • Reduced motion: if the diff adds or changes animation, prefers-reduced-motion should mean fewer/gentler, not zero (opacity/color transitions that aid comprehension can stay; drop movement/position animation). Full animation-quality review (easing, duration, what should animate at all) is out of your lens; per ~/.claude/dwarves-kit/docs/impl-playbook/frontend-design-engineering.md, that's the review-animations skill's job, not this one.

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.
