Key Concepts & Glossary
The whole app is built from a small set of ideas. Learn these and everything else
clicks into place. (This page is the hub — most other pages link back here.)
- Agent — an AI assistant with its own personality, instructions, model, and set
of switched-on capabilities. You can have many. See Building Your Own Agent.
- Session — one ongoing conversation thread with an agent. Switching sessions is
like opening a different chat. See Sessions & Conversation History.
- Turn — one exchange: your message plus everything the agent does in response
(which may be several steps and tool calls). Deleting a turn removes the whole thing
from the agent's memory of the chat.
- Ability — a switch that unlocks a bundle of tools. "Web Access", "Browser
Control", "Wiki Control" are abilities. Abilities = what an agent can do. See Abilities.
- Tool — a single concrete action the agent can call (search the web, send an
email, read a file). Tools come from abilities. See Tools & How They're Exposed.
- Skill — a knowledge pack: a written playbook the agent can pull in when a task
needs it. Skills = what an agent knows. See Skills (On-Demand Knowledge).
- Prompt — the standing instructions that shape an agent's behaviour and voice.
See Prompts & Context.
- Memory — facts saved across conversations and recalled automatically. See Memory.
- Page — a screen in your personal Dashboard workspace that the agent draws. See
Pages (Your Dashboard Workspace).
- Wiki article — a shared reference page (like this one).
The one-line mental model: **abilities = tools, skills = knowledge, prompts =
behaviour, memory = recall.** Full version in How Agents Work: The Mental Model.
