Glossary

The Olbrain vocabulary.

Plain definitions of the terms used across the platform. For how they fit together, see the concepts.

Olbrain
Olbrain is The Agent OS for building, running and governing agent systems that work together. Specialized systems connect through relevant shared context, clear responsibilities and handoffs, business-wide goals and common governance. Connections require scoped engineering and validation.
The orchestrator
The lead orchestrator inside Olbrain: an AI agent that builds the agent systems, directing a team of specialist sub-agents through discovery, build, and deployment.
Agency Protocol
Olbrain’s mechanism for giving each agent a self-identity — one accountable, exclusive actor — so its decisions are attributable and the enterprise can answer for them.
Self-identity
The agent’s own self: who it is and that it remains the same actor across time, answerable for its record. Distinct from external identity — authorization and access management — which governs only what an agent may access.
Agent brain
The definition of an agent — identity, tools, knowledge, channels, guardrails — that compiles into a deployable system prompt and runtime configuration. Versioned and immutable on publish.
BRD
A business-requirements document produced during discovery; the agent brain is generated from it.
Workflow
A directed graph built from typed step executors that an agent runs; steps fan out per item and aggregate. Olbrain ships 37+ typed step executors.
Tool · MCP
A capability an agent calls to act in the world, implemented as a Model Context Protocol (MCP) tool server.
Connector
An integration into an enterprise system or API an agent uses to access data and take action.
Knowledge
Enterprise data — documents and systems — that grounds an agent’s answers and actions.
Trigger
An event that starts an agent or workflow: a conversation, another agent, an external event, or a schedule.
Runtime
The execution mode for an agent. Three are live: conversational, workflow, and research.
Agent types
The five kinds of agent: Concierge (conversational), Operator (workflow), Analyst (research), Orchestrator (coordination), Designate (role-holding — humans supervise). See capabilities.
Context Service
Olbrain’s persistent, judge-gated agent memory — append-only, scoped global → agent → session.
CS-packet
Compiled working context, including memory and history, supplied to a model call. A context carrier, neither an identity construct nor a billing unit.
Audit log · receipt
An immutable, append-only record of every agent action; each action emits a signed, PII-free receipt.
Audit packet
An on-demand record of an agent action — produced by replaying it — for InfoSec, Risk, or a regulator.
CoF · Core Objective Function
An agent’s declared purpose, bound at creation, that orients its behavior and stays stable over time — a first-class primitive.
