Glossary

In brief

This glossary defines the terms the Composable Reference Architecture uses, including the four planes, agent and channel surfaces, the capability registry and progressive disclosure. Each entry is one line, so it doubles as a quick reference while reading any section.

Agent Main — the supervisory layer of the Cognition Plane: routing, context, guardrails, approvals, measurement and memory.
Agent surface — a place where people meet the agent engine, defined by its audience and its trust regime. Distinct from a channel surface (a route to a prospect) and from a sub-agent (an internal specialist). See Section 12.
Agent-as-retriever — retrieval as a behavior of the model, through tool calls, rather than a step completed before the model starts reasoning. See just-in-time context.
Agentic GTM Architecture & Engineering — the revWorx approach to realizing Autonomous GTM Operations. The instantiation, not the vision.
Autonomous GTM Operations — the vision: a go-to-market system that reasons, acts and extends itself, with people setting direction and owning approvals. Autonomous in execution, not unsupervised.
Broad bridge — the pillar of the web surface that exposes the widest set of registered abilities; used for bulk reads and routine writes.
Capability — a role inside the orchestration engine, with instructions, output expectations and bounded tool access. Not a separate process or subscription.
Capability registry — a machine-readable catalog in which a web platform’s extensions declare what they can do; the interface the three pillars read. WordPress’s abilities registry is today’s instance.
Channel surface — a route to a person, such as search, email or direct mail. Defined by the job it does and the record it writes to; provided by tools, not a tool itself.
Cognition Plane — the reasoning and orchestration layer: one engine surfaced to people through one or more agent surfaces, a supervisory layer and specialist sub-agents.
Composable — built so that any component inside a plane can be added, replaced or retired without changing the other planes or the cost of the whole. Depends on the five conditions in Section 4.3.
Context window — the model’s working memory for a single request, measured in tokens. Everything the model can see while it works must fit inside it.
Context Engine — four versioned libraries (ideal-customer personas, brand narratives, proof points, revenue levers) supplied to every sub-agent at runtime.
CRM Agent — implementation term, not a pattern term. The agent surface embedded in the CRM interface for the client’s staff: Describe / Demonstrate / Do with human-in-the-loop gates on writes. See agent surface.
Custom-built server — an MCP server we write ourselves for a system that has no usable one. Two exist in the current stack.
Data Plane — the master records the business owns, separated from the external sources it reads.
Declarative interface — an interface in which the operator states the outcome wanted rather than the steps to take. The conversational surface of this architecture is declarative.
Execution Plane — the infrastructure the Tool Plane runs on: hosts, containers, gateway, build and release tooling, domains.
Governed change platform — the pillar of the web surface through which every irreversible write passes: snapshots, dry runs, approvals, design checks, guarded updates.
GTM Agent — implementation term, not a pattern term. The operator-facing agent surface: orchestrates GTM motions, routes the decisions that stay with people, carries KPI alerts and is primarily responsible for managing and orchestrating the sub-agent groups on the operator’s behalf. See agent surface.
Ground-truth layer — the pillar of the web surface used for diagnosis and agent infrastructure: direct code execution, binary uploads, site-side memory and skills.
Interface revolution — the shift of software’s primary surface from the graphical interface to conversation with an agent. The premise of Section 2.
Just-in-time context — loading only what the current task requires, when it is required, through tool calls rather than a pre-built index.
Load everything, always — the default MCP pattern, in which every connected tool’s definition is carried in context on every turn.
MCP (Model Context Protocol) — the protocol by which capabilities expose discoverable, callable tools to agents. Here, the integration paradigm of the whole stack.
MCP gateway — the single point between agent and servers that supplies credentials, enforces limits and routes calls.
Operator surface — the agent surface through which operators direct the system: a single conversational interface plus the screens kept for seeing, approving and overriding (Section 12). One of several surfaces of the same engine; see agent surface.
Operator-oriented tool — software designed to be worked by a person at a screen: its own GUI, integration pattern and data plane. The kind of tool the interface revolution displaces.
Owned path — the way a capability is met from what the architecture already holds: existing data, existing tools and agent work. The working default for every category in Table 3, not a placeholder.
Premium path — the way a capability is met by adding a specialist product, taken when a stated trigger in the business justifies the cost. Table 3 names the trigger alongside each premium path.
Progressive disclosure — discover, inspect, execute: the agent finds tools on demand, loads only the definition it is about to use, and calls it. Keeps standing context cost flat in server count.
Revenue Lever Map — the graph linking each outcome to its drivers and gates; what turns measurement into action.
Standing context cost — tokens consumed on every turn before any work is done. Distinct from per-task cost, which scales with the work.
Supervisor — the routing component of Agent Main: directs each piece of work to the sub-agent whose capability, task and context fit. A component, not an agent surface; the named agents (CRM Agent, GTM Agent, WEB Agent) are surfaces.
Three-pillar pattern — the agentic web surface: a governed change platform, a broad bridge and a ground-truth layer, all reading one abilities registry.
Token — the unit in which model usage is metered and billed; roughly three-quarters of an English word.
Tool bloat — context and token cost consumed by tool definitions under load-everything; grows linearly with tool count.
Tool Plane — the universal MCP surface: seven functional clusters plus the channel surfaces they provide.
Tool selection consistency — how reliably an agent picks the right tool for a task. Degrades with flat lists of many similar tools; improved by search-then-inspect.
Trust routing — sending each write to the surface that can govern its risk: bulk and routine work through the bridge, irreversible changes through the governed platform, diagnosis through ground truth.
Waterfall enrichment — trying data sources in sequence until one returns a satisfactory result.
WEB Agent — implementation term, not a pattern term. The public agent surface resident on the client’s website, engaging visitors under guardrails with escalation to a human. See agent surface.
