Context Portability
Context portability is an AI interface design pattern that makes the payload an agent carries across app boundaries (credentials, conversation history, files, user preferences, prior tool outputs) legible and editable, so users and downstream systems can see and shape exactly what travels. This UX pattern addresses the boundary problem in cross-app agent workflows, where the richness of in-app context collapses into an opaque blob the moment the agent invokes a tool or hands off to another surface. By surfacing the handoff payload as a first-class object with structured fields, the pattern lets users inspect what the agent is about to share, redact sensitive details, and understand why a downstream app produced the result it did. It is the interoperability contract that makes composed, multi-tool agent products reviewable rather than black-boxed.
Use Case
Essential for cross-app agents, tool-calling assistants, and multi-step workflows where users benefit from inspecting and editing the context payload that travels across each boundary.
