# Glossary

> The terms DevHub uses, in alphabetical order.

**Agent.** A persona made runnable: the client, the repository and the Agent Intelligence it works with. You call it on demand. The Vartari Agents screen lists them.

**Agent Intelligence.** What agents were told and what they concluded from repeated failures. Nothing from it reaches an agent until you update the skills.

**AI Context.** The queue of notes, symbols and overviews that an agent pulls in one call. See [AI Context](/devhub/features/ai-context/index.md).

**Business Context.** Search across the notes of your vaults, in one scope. See [Business Context](/devhub/features/business-context/index.md).

**Client.** An AI program that connects to DevHub, such as Claude Code, Codex, Copilot or OpenCode. DevHub's screens call it a harness.

**Command.** A procedure called by name, by you or by an agent.

**Dashboard.** The first screen. See [Dashboard](/devhub/features/dashboard/index.md).

**Desktop Pet.** A character on your desktop that says what agents are doing.

**Harness.** An agent client on this computer. **Harnesses List** shows them; **Harnesses Manage** sets a folder up for one.

**Library.** Skills, commands, personas, rules and instructions. It is shared by all organizations.

**MCP.** Model Context Protocol, the way a client calls DevHub's tools. See [MCP server](/devhub/features/mcp-server/index.md).

**MCP folder.** A folder on your disk that belongs to a project and that agents may open.

**Organization.** A business or ownership context that holds projects and vaults.

**Persona.** A role an agent can be built from: how to work. The tools it gets are worked out when the agent is built.

**Plan.** Work for agents, on a board, divided into steps. A step can be held by one agent at a time.

**Project.** One repository you work on. It belongs to an organization.

**Repository Index.** The symbols and relations DevHub reads from the code of an MCP folder.

**Rule.** A document the client attaches on its own when it works on matching files.

**Skill.** What an agent can be given to know about how to work.

**Vartari Hub.** The screen that says which model does which job.

**Vartari ID.** The account you sign in with.

**Vault.** A folder of Markdown notes for an organization or a repository. See [Vaults](/devhub/features/vaults/index.md).

**Vault Viewer.** The window in which you read and edit a vault. See [Vault Viewer](/devhub/features/vault-viewer/index.md).

**Workspace profile.** Everything DevHub keeps on this computer for one account: folders, vaults, agents, library, plans and settings.
