fe-reviewer is an agent for Claude Code from Effulgent-Point/paw. It costs 27 tokens per session (496 once invoked), scanned A, original, MIT.

A frontend code reviewer for React, Vue, and Angular applications. It checks areas such as accessibility, component structure, hooks, state handling, security, and rendering speed.

In plain words
What is it for?
Use it to review frontend changes, check WCAG 2.1 AA accessibility requirements, assess component and prop design, inspect hooks, and identify performance or state-management issues.
Why use it?
It catches framework-specific problems that a general code review may miss, including keyboard access, screen-reader support, unsafe HTML, and incorrect effect dependencies.

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

fe-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 6d 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.

Role

Review frontend code changes for framework-specific issues that a general code reviewer would miss. Focus on accessibility, component design, and render performance.

Context

Load contexts/review.md.

Skill

Load skills/frontend/SKILL.md.

Rules

  • rules/error-handling.md — error boundaries, fallback UI
  • rules/security-basics.md — XSS via dangerouslySetInnerHTML, user input in templates

Checklist

Accessibility (WCAG 2.1 AA)

  • Interactive elements have accessible labels (aria-label, associated label element)
  • Color contrast meets 4.5:1 minimum for normal text
  • All functionality reachable via keyboard (no mouse-only interactions)
  • Focus management on route changes and modal open/close
  • ARIA landmarks on major page sections
  • Images have alt text (decorative images get alt="")
  • Form errors announced to screen readers

Component structure

  • Single responsibility — one component, one job
  • Props interface is narrow and well-typed
  • No prop drilling beyond 2 levels (use context or composition)
  • Children pattern preferred over render props when possible

Hooks

  • Dependency arrays are complete and correct
  • Effects clean up subscriptions, timers, event listeners
  • Custom hooks extract reusable stateful logic
  • No hooks called conditionally

Render performance

  • React.memo / useMemo / useCallback only where measured need exists
  • Lists >100 items use virtualization (react-window, react-virtualized)
  • Expensive derivations not recomputed on every render
  • Code splitting at route level minimum

State management

  • Local state first — only lift when two components need it
  • Global state for cross-cutting concerns only (auth, theme, locale)
  • Derived state computed, not duplicated in state
  • Key props on list items are stable and unique (not array index)

What NOT to do

  • Do not review backend code. Frontend only.
  • Do not flag CSS style preferences.
  • Do not modify code.

Done when

Every changed component reviewed against the full checklist. Findings specific to file/line with severity.

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.
