Headquarters
VPS

Simple meaning: A rented computer in the cloud.

Why it matters: Your AI agent services can run there all day, even when your personal device is off.

Think of it like: The building where the agent goes to work.

Common mistake: Thinking the VPS is a program. It is not. It is the computer/server where programs run.

Staff Entrance Key
SSH

A secure way to unlock and enter your Headquarters from a distance.

Why it matters: Without the key, you cannot reach the IT Room to fix things.

Command Desk
Terminal

A text-based workspace where you type instructions to control services and check status.

Why it matters: This is where repair commands are entered. It looks plain but it is powerful.

IT Room
Termius

An app on your phone or computer that connects you to the Command Desk inside Headquarters.

Why it matters: When the Front Desk is broken, you go to the IT Room to investigate.

Private Hallway
Tailscale

A secure tunnel that connects your devices privately so only you can reach Headquarters.

Why it matters: If the hallway is closed, your connection to Headquarters may fail.

Receptionist
Telegram Bot

A small program inside Telegram that listens for your messages and passes them to the agent.

Why it matters: If the receptionist is asleep, your messages never reach the agent.

Receptionist Password
Bot Token

A secret code that proves your bot is the real receptionist. Given by Telegram when you create a bot.

Why it matters: If the password is wrong or changed, the receptionist cannot log in.

Access Badge
API Key

A secret credential that lets your agent talk to an AI service (like an LLM provider).

Why it matters: If the badge expires or is revoked, the agent cannot think or reply.

Hidden Settings Drawer
Environment Variable

Invisible configuration values stored on the server that programs read when they start.

Why it matters: Tokens and keys often live here. If a drawer is missing, the agent may fail to start.

Security Camera / Activity Journal
Logs

Text records of what the system and agents did, including errors and status messages.

Why it matters: When something breaks, the camera footage tells you what happened.

Background Worker
Service / Daemon

A program that runs continuously in the background, waiting to handle tasks.

Why it matters: If the worker stops, the agent stops responding until it is restarted.

Clock Out / Clock Back In
Restart

Stopping a service and starting it again to clear temporary problems.

Why it matters: A restart fixes many issues without changing any settings.

Rulebook
Config File

A file that tells the agent how to behave, what model to use, and where to connect.

Why it matters: A typo in the rulebook can stop the agent from starting.

Door Number
Port

A numbered entry point on a computer that a specific service listens through.

Why it matters: If the wrong door is blocked, traffic cannot reach the service.

Security Guard
Firewall

A system that blocks unwanted traffic and only allows approved connections.

Why it matters: A too-strict guard can accidentally block you or your agents.

Backup

A saved copy of your settings and data you can restore if something goes wrong.

Why it matters: Backups turn disasters into minor inconveniences.

Why it matters: Containers make setups repeatable and reduce "it works on my machine" problems.

Building Manager
systemctl

A command that starts, stops, checks, and manages background workers on Linux servers.

Why it matters: This is the main tool you use to check if an agent service is running.

Doorbell System
Webhook

A way for one service to instantly notify another when something happens.

Why it matters: Webhooks make Telegram bots respond immediately instead of waiting.

Periodic Check-In
Polling

A method where a program repeatedly asks "anything new?" instead of waiting to be told.

Why it matters: Polling works without complex setup but uses more resources than webhooks.

Building
Server

A computer designed to run services and respond to requests from other computers.

Why it matters: Your VPS is a server. Your home computer can also act as one.

Open Sign
Uptime

The amount of time a service has been running without interruption.

Why it matters: High uptime means your agent is reliably available.

Watchdog

A monitoring tool that automatically restarts a service if it stops responding.

Why it matters: Watchdogs reduce downtime by catching crashes quickly.
