Nufar Gaspar and Nathaniel Whittemore distinguish private agents, shared knowledge used by individual agents and genuinely shared team agents. A common skill libraryAn AI agent skill is a reusable package of instructions, resources, and tool guidance for performing a bounded kind of work. is useful standardization, but it is not the same as one agent with shared memoryAI agent memory is stored information that an agent can retrieve and use across steps, sessions, or changing contexts., configuration and ownership. They identify expert, common-work, bridge and chief-of-staff agents as four useful patterns, with expert knowledge hubs often providing the easiest starting point.
Nufar Gaspar organizes the design process around five questions: what the agent does, where it lives, what it knows, what it can touch and how it is run. Teams need explicit roles, a definition of done and a list of prohibited actions. Knowledge should be gathered from its actual owners, reconciled when sources contradict, approved and maintained rather than silently accumulating into a new shared truth.
PermissionsAn agent permission boundary limits the information, tools and actions an AI agent can use during a task. require more than deciding what an agent can read. Teams must also control who can ask it questions, where its answers appear and which person's access it uses. Information that one participant may legitimately retrieve must not leak into a shared channel whose other members lack that access. Clear ownership, visible decisions, correction procedures and a small monitored pilot help preserve trust as tools and organizational needs change.
The discussion recommends choosing the simplest implementation that people will actually use, rather than building a custom harness prematurely. Shared agents are the wrong choice when personal taste must remain distinct, nobody will maintain the knowledge or coordination adds more work than it removes. The durable value lies in agreed standards and curated knowledge, which can survive later changes of vendor or model.
