One objective, distinct responsibilities.
From an objective to usable work
An objective expresses what the person wants accomplished. Home keeps that objective connected to the relevant information, independent work, decisions and outputs. It can answer directly when that is enough, or assign bounded work to Companions when different responsibilities benefit from independent execution.
Consider an operational review: one Companion investigates the available information, another compares options, and another prepares the deliverable. Home coordinates those contributions and identifies what is still missing. The examples describe operating relationships; the actual sources, actions and result depend on the environment’s approved capabilities.
Home supervises the whole objective
Home provides the coordinating view across an assignment. It preserves the purpose of the work as individual agents investigate, return findings or need a decision. A local success from one participant does not automatically mean the overall objective is complete: other dependencies, required actions or unanswered questions may remain.
Coordination includes deciding which responsibilities can proceed independently, bringing authorized findings together and directing follow-up. The person can change the objective or address a particular Companion. Home’s supervisory role does not grant it permission to override organizational policy or another agent’s boundaries.
A Companion is an operating participant
A Companion has its own identity, work state, assigned model connection, available tools and operating scope. Separate Companions can progress on separate assignments without becoming interchangeable names over one conversation. The window presents the agent’s work; it is not the agent’s identity or authority.
Findings shared between agents retain their origin and context. A handoff supplies the permitted information needed for the recipient’s next step. It does not copy every source, credential or permission belonging to the sender. See the Companion reference for direct collaboration and Composite Companions.
Proposals and effects have different owners
A model can reason about information and propose a tool action. The operating environment decides whether that particular action is permitted within the current scope. Allowed work can proceed; work requiring review waits for that decision; prohibited work is refused.
Application functionality provides the operation itself. Governance determines whether the agent may use it. The interface presents progress and outcomes. Keeping these responsibilities distinct prevents a confident explanation, visible button or model-generated plan from becoming authority by itself.
A useful result includes its limits
An agent’s explanation, a prepared artifact and a confirmed external change answer different questions. An explanation describes the work. An artifact is something to inspect or reuse. A system’s reported outcome establishes what happened at that system’s boundary. Failure, refusal and an unresolved response must remain distinguishable from completion.
Review the action and its reported result together. A saved view can help explain a decision without proving that every connected source is current. The current Trust and Security references describe the scope of reviewable records and security commitments; this architecture page does not add a universal recovery or exactly-once guarantee.
Presentation follows the work
Quick Input gives Home a continuing place to receive an objective and show its response. Companion windows, Living Surfaces, Apps and Working Groups expose different parts of that work. Moving, opening or closing a presentation surface should preserve the work it represents unless the person deliberately cancels or changes it.
This public website demonstrates those relationships within its guest capabilities. It does not inherit the visitor’s native desktop access or an installed organization’s accounts. For deployment questions and platform-specific availability, use Enterprise, Security and the accepted native release information.
