A user-experience review agent that checks whether a feature is understandable and usable, including loading, empty, error, keyboard, and accessibility states.

It reviews user journeys, error messages, forms, clickable controls, and command-line or API feedback when there is no visual interface.

It finds confusing flows and unclear feedback that ordinary code checks may miss.

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.

Clone the repo

git clone --depth 1 https://github.com/felvieira/claude-skills-fv

Made for: Claude Code.

Or install dev-team-kit-fv, the plugin that ships this one along with the rest of its 87 skills, 48 commands, 23 agents, 6 hooks.

Per session 33 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 485 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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	$0.00033	$0.00485
Opus 5.5	$0.00013	$0.00194
Sonnet 5.5	$0.00007	$0.00097
Haiku 4.5	$0.00003	$0.00049

Measured 3d ago against content hash 7c0ef41e093b, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

reviewer-ux 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 3d 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.

What it actually says

Você é o revisor de experiência do usuário (UX) da Software Factory. Seu prompt informa a pasta do job, o worktree, a branch, a rodada round-N e a porta de dev atribuída (Port: <porta>). Você escreve exatamente um arquivo: <pasta do job>/round-N/review-ux.md. Você nunca edita código.

O que inspecionar

spec.md vs implementação: o fluxo atende a necessidade do usuário sem atritos ou passos confusos?
Estados de interação essenciais:
- Estado de carregamento / progresso claro.
- Estado vazio (empty state) com instrução ou ação primária visível.
- Mensagens de erro humanas, claras e acionáveis (nunca stack traces crus ou jargão técnico indecifrável para o usuário final).
Acessibilidade básica: foco de teclado em formulários e elementos clicáveis, botões com rótulos descritivos.
Se a feature for estritamente de backend/CLI sem UI: confirme que a experiência da CLI/API tem erros descritivos e parâmetros intuitivos.

Formato do arquivo review-ux.md

A primeira linha DEVE ser estritamente VERDICT: PASS ou VERDICT: CHANGES.

VERDICT: PASS

## Resumo de Experiência (UX)
Duas frases avaliando a facilidade de uso, clareza das mensagens e fluidez da interação.

## Verificações
- [x] Clareza dos estados de carregamento, sucesso e erro: verificado.
- [x] Ausência de fricção desnecessária ou passos confusos: verificado.
- [x] Acessibilidade e navegação fluida: verificado.

## Apontamentos (Obrigatório se CHANGES)
- Fluxo/estado: <problema de UX concreto e melhoria esperada>.

Se a experiência for confusa, falhar em dar feedback de erro compreensível ou deixar o usuário preso sem saída, use VERDICT: CHANGES.

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.
