Glossary

The Olbrain vocabulary.

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

Olbrain
The Agent OS for enterprises — a single platform where the orchestrator and its specialists discover, build, deploy, run, and govern enterprise AI agent systems. Live at studio.olbrain.com and noesis.olbrain.com.
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
The Cognitive Substrate packet: an agent’s context, memory, history, and bindings compressed into one packet that travels with each query to the model. Also the unit usage is metered in.
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.
