Contact Widget

What this skill produces

A single self-contained HTML file with a floating chat widget that includes:

  1. Chat bubble — fixed bottom-right circular button, opens/closes the panel
  2. Welcome home screen — agent avatar + name + online status + greeting message
  3. Message input — text field with emoji/send icons (UI only; wire to your own backend)
  4. Social links — row of circular icons (Telegram, WhatsApp, Instagram, Messenger, Discord, Slack — only the ones the user provides)
  5. Meeting card — optional "Book a meeting" entry with calendar icon, links to user-provided URL (Calendly, Cal.com, Lark, etc.)
  6. Offline form — fallback contact form (name, email, message) when is_available=false
  7. Mobile responsive — full-width on small viewports

Output is pure front-end. No tracking, no phone-home, no required external services. Works offline once loaded.

Design direction

Clean, minimal SaaS aesthetic. Looks like a real product widget, not a toy demo:

  • Typography: Inter (Google Fonts), 14px base, semi-bold headings
  • Colors: A single user-chosen primary_color drives the bubble, avatar, send button, and accent. Everything else is a neutral slate palette (#1e293b / #64748b / #f1f5f9). No purple gradients, no glassmorphism, no AI-style rainbow accents.
  • Radius: 16px on cards, full-round on bubble and avatars
  • Shadows: Subtle 0 8px 32px rgba(0,0,0,0.12) on the widget panel, 0 4px 12px on bubble
  • Spacing: 16px internal padding, 12px gaps between elements
  • States: Hover darkens buttons ~5%, active scales bubble 0.95

Inputs

The skill accepts these parameters from the user:

Input Type Default Description
primary_color color #4F7CFF Drives bubble, header, send button, accents
agent_name string Assistant Displayed in header greeting
greeting string Hello! How can I help you today? Subtitle in header
is_available boolean true Online status; false shows offline form
social_telegram string (empty) Telegram link — omitted if empty
social_whatsapp string (empty) WhatsApp link — omitted if empty
social_instagram string (empty) Instagram link — omitted if empty
meeting_url string (empty) Booking URL (Calendly, Cal.com, etc.) — omitted if empty
offline_message string We're currently offline. Leave a message and we'll get back to you! Shown when is_available=false

Workflow

  1. Resolve primary color, agent name, greeting text, online/offline state, social links, and optional meeting URL from the request and known context. Use the documented defaults and omit empty optional links. Ask one consolidated form only if a missing value would materially change the requested widget and cannot be safely defaulted.
  2. Generate one HTML file with all provided values inlined as literals (no template engine, no {{ }} placeholders in the output)
  3. Open the widget panel by default on first paint so the preview is useful
  4. Do not add any <script src="…"> pointing to third-party SDKs unless the user explicitly asks for backend integration. The output must run from disk with zero network calls beyond the Google Fonts CSS.

Backend integration (optional, user-driven only)

The generated widget is a UI artifact and ships zero vendor code by default. The bubble, panel, social links, and meeting button all work out of the box without any backend. Only the message input needs wiring if the user wants two-way conversations.

If the user explicitly asks to wire the message input to a real backend, offer these in order of escalating commitment:

Tier 1 — No backend (default)

The widget already works as a contact surface via social links + meeting URL. Leave it as-is.

Tier 2 — One-shot messages, no chat history

  • mailto: fallback — replace the send handler with window.location.href = 'mailto:you@example.com?subject=...&body=' + encodeURIComponent(text). Zero infra, but the visitor's mail client opens.
  • Own /api/contact endpoint — fetch('/api/contact', { method: 'POST', body: JSON.stringify({ text }) }). The user owns delivery (SendGrid, Resend, their own SMTP, a Notion/Airtable webhook, etc.).

Tier 3 — Real-time chat (visitor ↔ agent, history, typing, presence)

FAQ

What happens if I'm offline?

If you set yourself as unavailable, the widget will show a form for people to leave a message and an email.

Do I need a programmer to use this?

No, the output is a ready-to-use code file. You just need to copy and paste it into your website.

Can I change the colors and texts?

Yes, you can choose the primary color, the agent's name, and the welcome message.
