Proof of Concept (PC)

A Proof of Concept (PC) is a preliminary implementation used to validate whether a proposed approach or system can work in practice, often used in agent engineering to test capabilities or behaviors before committing to full development.

Role in Agent Workspaces

In the context of building agent systems, PCs serve a specific investigative function: they are used to answer risky questions early in the development process. As noted in the talk To Give an Agent a Workspace: Laying a Foundation for Messy Forever Work, "PC's answer risky questions" — suggesting that proof-of-concept work is positioned as a deliberate risk-reduction strategy, surfacing unknowns and validating assumptions before they become expensive to unwind in a more complete system. 42:00

This framing positions the PC not merely as a demo or prototype, but as an explicit tool for de-risking architectural and capability decisions in agent development — particularly relevant when building systems intended for long-running or complex ("forever") work where the cost of late-stage failure is high.
