From Prompting to Specifying: Logic's Spec-Driven Agents

The "Prompt" is becoming an antique. The "Spec" is the new primitive.

Logic has launched a platform for "fully managed AI agents" based on natural-language specifications. While it sounds like prompting, the underlying shift is toward determinism.

The Prompt vs. The Spec

A prompt is a request for an output. A spec is a definition of a system.

By moving to a spec-driven model, Logic is attempting to solve the "agentic drift" problem—where agents deviate from the desired path during complex, multi-step tasks. A spec defines the boundaries, the required outcomes, and the failure states, turning the agent's execution into a predictable process rather than a stochastic guess.

The Signal

This is a move toward Deterministic Agency. If we want agents to handle production-grade software or financial transactions, we cannot rely on "vibes" and prompt-tuning. We need specs.
