PalmClaw: A Native On-Device Agent Framework for Mobile Phones

PalmClaw is an open-source agent framework designed to run natively on mobile phones. It manages sessions, memory, skills, tools, and the agent loop locally, while exposing phone capabilities through device tools with explicit arguments, structured results, and defined execution boundaries. The paper reports an 11.5% relative improvement in task success and a 94.9% reduction in completion time compared with the strongest baseline. It also claims lower setup burden and provides execution traces showing how the framework applies action boundaries. The implementation is available on GitHub.
