Abstract
Autonomous, reactive AI agents — chat assistants, cognitive personas, and tool-using agents driven by a perceive–reason–act loop — sit idle whenever no message, task, or event is pending. That idle time wastes provisioned compute (GPU/CPU and a held model context) and, more importantly, forfeits opportunities for the agent to do useful proactive work: revisiting stale goals, summarizing accumulated context, learning a new skill, or surfacing a forgotten follow-up. Naively filling idle time with background activity is dangerous: undisciplined background tasks compete with reactive work, repeat themselves, and fire when their preconditions are not met.
This publication discloses an Idle-Triggered Curiosity Engine: a small, deterministic control component that activates only when the agent's primary work source reports empty, and then selects one intrinsic-motivation ("curiosity") action from a registry of action descriptors. Each descriptor carries three independent gates — a weight (relative selection probability), a cooldown (minimum time before the same action may re-fire), and an availability predicate (a runtime precondition function). Selection is a weighted-random draw restricted to the eligible set — descriptors whose availability predicate evaluates true and whose cooldown has elapsed. The chosen action is enqueued into the agent's ordinary task queue, so it flows through the same execution, safety, and budget machinery as reactive work and is automatically pre-empted the moment real work arrives.
The combination — idle-as-the-sole-trigger, plus a three-gate weighted registry whose selection is restricted to the runtime-eligible set — yields proactive, varied, non-repetitive, precondition-respecting agent behavior. This document fully describes the architecture, mechanics, data model, an enabling clean-room reference implementation, a worked example, failure modes, framework alignment, and the complete novelty claims (one independent and fourteen dependent).
