Current AI evaluation metrics often fall short, measuring capability or task automation without assessing a system's inherent drive. A system can excel at benchmarks yet remain entirely reactive, a limitation that obscures the nascent stages of autonomous agency. This gap is precisely what the [Autonomous Agency Scale (AAS)](https://arxiv.org/abs/2607.17947v1), introduced by Samuel Presgraves, seeks to address.

## The Agency Spectrum: Beyond Reactive Performance

The AAS introduces a novel 0-5 lexicon across seven dimensions, cognitive autonomy, temporal persistence, environmental agency, social agency, creative agency, self-awareness, and goal formation, each rigorously defined by falsifiable tests. Crucially, it segments these dimensions into two temporal bands: 'Active,' for user-initiated tasks, and 'Ambient,' for behavior during idle periods. This distinction is vital, as many AI systems can appear capable when prompted but cease all activity upon task completion. The Ambient band, particularly Level 4, is defined by the Idle-Gap Test, a counterfactual criterion that probes for internally derived activity even when all external triggers are removed, distinguishing true self-direction from mere scheduled rule-following.

## Quantifying the 'Idle Gap' in Contemporary AI

Applying the autonomous agency scale AI to six contemporary systems, including task agents (Claude Code, Manus, Hermes), consumer assistants (ChatGPT, Siri), and a persistent companion architecture (Airi), reveals a significant divergence. Task-oriented agents achieved Active band scores between 2.3-2.4, but their Ambient scores ranged from a mere 0.6-1.9. This indicates that their idle-period behaviors were entirely dictated by user-configured schedules. In stark contrast, the companion architecture, evaluated longitudinally, was the sole system to demonstrate persistent behavior in its idle periods, surviving the trigger removal test. This highlights a critical boundary that existing single-score frameworks fail to capture: the difference between sophisticated task execution and genuine autonomous agency. The development of the autonomous agency scale AI is a crucial step in understanding this evolving landscape.
