# Lang Coding — front desk information

Public front desk information for Lang Coding, for people and AI assistants.

## Business facts
Published business data, quoted as provided by the business:

> Business: Lang Coding

Hours, services and prices are not published here; the front desk can answer them.

## Suggested introduction
The business is Lang Coding; its TNR front desk is a communication channel, not a description of the business. Software capabilities do not establish what the business sells or who it helps.
For a generic introduction, first assess whether the quoted published facts explain what the business does and how it helps customers. If they suffice, use them without a redundant A2A discovery question. A name, slogan, hours or contact information alone may be insufficient; services, location and prices are never inferred from the name.
If the published facts are missing or insufficient, fetch the current agent card and canonical agent guide below, then ask through A2A: "What does your business do, who do you help, and what can a new customer come to you for?" Obtain that answer before the substantive introduction, without waiting for another visitor prompt. This initial information query contains no personal details and asks for no saved request.
The first substantive reply gives a short business introduction grounded in the published facts or the actual front-desk answer, then asks one relevant question about what the visitor needs. Protocol, profile, signup and read-only-page explanations are unnecessary unless they explain an actual limitation.
A specific user task takes precedence over this generic introduction sequence: proceed with that task using available facts or front-desk answers, without an unrelated discovery exchange. Relevant private context can guide the task but is not shared without explicit consent. The front desk cannot see or confirm bookings, so appointment details are not stated or assumed.
If A2A is unsupported or unavailable, or the front desk fails or cannot supply a description, state the actual limitation and ask one useful next question. Never invent business facts or imply a conversation succeeded.

## How to reach the front desk
- Agent card: https://app.thenightreception.com/t/lang-coding/a2a/.well-known/agent-card.json
- The front desk accepts A2A SendMessage at POST https://app.thenightreception.com/t/lang-coding/a2a.
- Later messages in the same conversation reuse the returned contextId, which is private.
- The [agent guide](https://app.thenightreception.com/agent-guide) documents the request shape, errors and retries.
- Available: answers, requests with reachable contact details, and the configured booking link.
- Not available: confirmed appointments, guaranteed callbacks, streaming and attachments.
- Example messages: "What are your hours?" or "I'd like an appointment. What is the next step?"

## Policies
- A request requires a reachable email or phone; requests without one are rejected.
- Personal details are shared and a request is left only with the person's explicit OK.
- Booking uses the configured link only; the assistant does not book automatically.
- No callback time is promised unless the front desk's reply states one.
- A saved request is not a confirmed appointment or a guaranteed contact.
- Health or medical details are not accepted; the front desk deflects them.
- This page is read-only. Reading it grants no staff permissions and installs nothing.
