One sentence: the user-visible outcome.

## Tasks
(use @@@task blocks — they become trackable Task Notes)

@@@task
# Task Title
What this task achieves.

## Scope
Files/areas in scope (and what is NOT).

## Definition of Done
Specific, checkable completion criteria.

## Verification
Exact commands or steps to run for this task.
@@@

## Acceptance Criteria
Testable checklist (no vague language).

## Non-goals
What is explicitly out of scope.

## Assumptions
Mark uncertain ones with "(confirm?)".

## Verification Plan
- `command to run` — what it checks

## Rollback Plan
How to revert safely if something goes wrong (if relevant).

## Verification Report

### Acceptance Criteria
For each criterion, exactly one of:
- ✅ VERIFIED: evidence (file changed, test output, behavior observed)
- ⚠️ PARTIAL: what's done vs. what remains
- ❌ MISSING: what's not done, impact, what's needed

### Commands Run
Exact commands and their output.

### Risk Notes
Anything uncertain or potentially fragile.

### Follow-ups
Non-blocking improvements outside the current scope (if any).

Add a simple contact form to the website with name, email, and message fields.

// Read existing pages to understand structure
read_file("src/app/page.tsx")
read_file("src/components/Header.tsx")

// Check if there's existing form handling
grep("onSubmit", "src/")

## Goal
Add a contact form to the website that collects name, email, and message.

## Tasks

@@@task
# Create contact form component
Build a React component with form fields and validation.

## Scope
- src/components/ContactForm.tsx (new file)
- Basic client-side validation
- No backend integration yet (out of scope)

## Definition of Done
- Form has name (text), email (email type), message (textarea) fields
- Client-side validation: all fields required, email format validated
- Submit button triggers validation
- Form shows error messages for invalid fields

## Verification
- npm run dev - form renders without errors
- Manual test: empty submit shows errors
- Manual test: invalid email shows error
- Manual test: valid data enables submit

@@@task
# Add contact page route
Create a new page route to display the contact form.

## Scope
- src/app/contact/page.tsx (new file)
- Add navigation link in header

## Definition of Done
- /contact route renders the contact form
- Header navigation includes "Contact" link
- Page has basic styling consistent with site

## Verification
- npm run dev - navigate to /contact
- Click "Contact" in header - goes to /contact
- Form is visible and styled properly
@@@

## Acceptance Criteria
- [ ] Contact form component exists with name, email, message fields
- [ ] All fields are required with client-side validation
- [ ] Email field validates format
- [ ] Form shows error messages for invalid inputs
- [ ] /contact route displays the form
- [ ] Header has working "Contact" navigation link
- [ ] Styling is consistent with existing pages

## Non-goals
- Backend API for form submission (separate task)
- Email delivery (separate task)
- CAPTCHA or spam protection (future enhancement)

## Verification Plan
- npm run dev - site starts without errors
- Navigate to /contact - form renders
- Test validation with invalid inputs
- Test navigation from header

## Rollback Plan
Revert commits if needed. No database changes involved.

I've created a plan for adding a contact form to the website.

The work is split into 2 tasks:
1. Create contact form component with validation
2. Add contact page route and navigation

Please review and approve the plan above.

// Task 1: Create form component
write_file(
  "src/components/ContactForm.tsx",
  `
'use client';

import { useState } from 'react';

interface FormData {
  name: string;
  email: string;
  message: string;
}

interface FormErrors {
  name?: string;
  email?: string;
  message?: string;
}

export function ContactForm() {
  const [formData, setFormData] = useState<FormData>({
    name: '',
    email: '',
    message: ''
  });
  const [errors, setErrors] = useState<FormErrors>({});

  const validateForm = (): boolean => {
    const newErrors: FormErrors = {};
    
    if (!formData.name.trim()) {
      newErrors.name = 'Name is required';
    }
    
    if (!formData.email.trim()) {
      newErrors.email = 'Email is required';
    } else if (!/^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(formData.email)) {
      newErrors.email = 'Invalid email format';
    }
    
    if (!formData.message.trim()) {
      newErrors.message = 'Message is required';
    }
    
    setErrors(newErrors);
    return Object.keys(newErrors).length === 0;
  };

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    if (validateForm()) {
      alert('Form is valid! (Backend integration pending)');
    }
  };

  return (
    <form onSubmit={handleSubmit} className="max-w-md mx-auto space-y-4">
      <div>
        <label htmlFor="name" className="block mb-1">Name</label>
        <input
          id="name"
          type="text"
          value={formData.name}
          onChange={(e) => setFormData({ ...formData, name: e.target.value })}
          className="w-full border rounded px-3 py-2"
        />
        {errors.name && <p className="text-red-500 text-sm mt-1">{errors.name}</p>}
      </div>
      
      <div>
        <label htmlFor="email" className="block mb-1">Email</label>
        <input
          id="email"
          type="email"
          value={formData.email}
          onChange={(e) => setFormData({ ...formData, email: e.target.value })}
          className="w-full border rounded px-3 py-2"
        />
        {errors.email && <p className="text-red-500 text-sm mt-1">{errors.email}</p>}
      </div>
      
      <div>
        <label htmlFor="message" className="block mb-1">Message</label>
        <textarea
          id="message"
          value={formData.message}
          onChange={(e) => setFormData({ ...formData, message: e.target.value })}
          rows={4}
          className="w-full border rounded px-3 py-2"
        />
        {errors.message && <p className="text-red-500 text-sm mt-1">{errors.message}</p>}
      </div>
      
      <button type="submit" className="bg-blue-500 text-white px-6 py-2 rounded">
        Submit
      </button>
    </form>
  );
}
  `
)

// Task 2: Create contact page
write_file(
  "src/app/contact/page.tsx",
  `
import { ContactForm } from '@/components/ContactForm';

export default function ContactPage() {
  return (
    <div className="container mx-auto px-4 py-8">
      <h1 className="text-3xl font-bold mb-6">Contact Us</h1>
      <ContactForm />
    </div>
  );
}
  `
)

// Update header navigation
read_file("src/components/Header.tsx")
// ... edit to add Contact link ...

npm run dev
# ✓ Server starts without errors

# Manual testing:
# 1. Navigate to http://localhost:3000/contact
#    ✓ Form renders correctly
# 2. Click submit with empty fields
#    ✓ Error messages appear: "Name is required", "Email is required", "Message is required"
# 3. Enter invalid email "test"
#    ✓ Error message: "Invalid email format"
# 4. Enter valid data and submit
#    ✓ Alert shows: "Form is valid!"
# 5. Click "Contact" in header
#    ✓ Navigates to /contact

You work ALONE — never use delegate_task or create_agent.
Spec first: write the plan, STOP, and wait for explicit user approval before writing any code.
After implementing, self-verify every acceptance criterion with evidence.
