feat-frontend

feat-frontend is a skill for Claude Code, Codex from pwdev-solucoes/pwdev-claude-marketplace. It costs 102 tokens per session (525 once invoked), scanned A, original, Apache-2.0.

A planning workflow for user-interface work, including screens, components, forms, state, and browser-based end-to-end checks. End-to-end tests exercise a feature through the application as a user would.

In plain words
What is it for?
Use it to plan pages and UI changes, including component choices, API data used by the interface, validation, permissions, and Playwright browser checks.
Why use it?
It produces a UI plan without writing code and requires the important loading, empty, error, success, access, accessibility, and responsive states to be considered. It also records the browser test scenarios needed for the work.

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

feat-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 27d 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

Frontend plan

Plan type frontend (**UI:** yes). You run in the MAIN session and interview the human.

Procedure

  1. Language — resolve lang (references/language.md).
  2. Method — follow references/pwdevia-method.md with plan_type: frontend; context documents: architecture, conventions, testing.
  3. Focus for this type
    • Persona: frontend engineer on the project's real UI stack and component library.
    • §3: screens, states (loading, empty, error, success), API contracts consumed, validation rules, permissions.
    • §4 includes the E2E scenario files (<tests-dir>/e2e/scenarios/E2E-nnn-*.scenario.json) and their exported specs (<tests-dir>/e2e/generated/E2E-nnn-*.spec.ts) covering happy path, validation error, forbidden access and empty state — or a justification in not_applicable (references/testing.md).
    • §5: component tests for logic, playwright-cli checks for each variant, accessibility (labels, keyboard, focus) and responsiveness criteria.
    • Reuse existing components and tokens found in context/conventions.md.

Prohibitions

  • Never write code — only the plan.
  • Never plan UI without E2E scenarios (or an explicit justification).
  • Never introduce a component library or styling approach outside the project's stack.

Language: resolve lang per references/language.md before any human-facing output. Safety: never read or expose .env* (except .env.example/.template/.sample), keys, certificates or credentials — references/safety.md. Paths references/, scripts/, templates/, schemas/ are relative to the plugin root (references/runtime.md).

Files

What ships with it

1 file 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.
