What's this about?
PalmClaw is a framework for running full multi-step agents — tool calls, observation, iteration — natively on a mobile phone, rather than on a server the phone talks to. (HF 7↑)
What exactly is "on-device"?
The model and agent loop run on the phone's own chip: private (your screen contents never leave the device), offline-capable, no per-call cloud costs. The challenge is that agents need many model calls per task, and phone hardware is tight — hence a dedicated framework for tool integration and memory under mobile constraints.
Why does it matter?
Phone-controlling agents are clearly coming (Apple/Google are both building them); whether they run on-device or in the cloud decides the privacy architecture of the next platform shift.
