First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/validate-frontend/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

Validate Frontend Skill

CLAUDE: When this skill is invoked with /validate-frontend, run these commands in sequence:

cd frontend && bun run type-check && bun run lint && bun run test -- --run

Purpose

Validates the web frontend codebase (Vite + React + TypeScript) for type safety, lint compliance, and test correctness.

Usage

/validate-frontend

What It Validates

Tier 0: TypeScript (fastest feedback)

cd frontend && bun run type-check
  • Catches type errors before runtime
  • Validates all .ts and .tsx files
  • Uses tsconfig.json configuration

Tier 1: ESLint

cd frontend && bun run lint
  • React hooks rules
  • React refresh compliance
  • Import ordering
  • Code style consistency

Tier 2: Unit Tests

cd frontend && bun run test -- --run
  • Runs Vitest in single-run mode
  • Tests components, hooks, and utilities
  • Uses Testing Library for React

Full Validation Command

cd frontend && bun run type-check && bun run lint && bun run test -- --run

Additional Commands

E2E Tests (requires browser, run before PR)

cd frontend && bun run test:e2e

Integration Tests

cd frontend && bun run test:integration

Coverage Report

cd frontend && bun run test:coverage

Interactive Test UI

cd frontend && bun run test:ui

Success Criteria

  • All TypeScript files compile without errors
  • Zero ESLint violations
