Summary

RS-Claw is a novel remote sensing (RS) agent architecture designed to overcome limitations in existing multi-modal large language model (MLLM) frameworks for RS intelligence. Current RS agents use passive tool selection, either through full tool registration (Flat) or retrieval-augmented generation (RAG), which struggle with context load and toolset completeness in complex, long-horizon tasks. RS-Claw redefines tool selection as an active exploration process. It employs skill encapsulation to hierarchically structure tool descriptions, allowing the agent to initially select relevant skill branches using only tool summaries, then dynamically load detailed descriptions for precise invocation. This active paradigm significantly reduces the agent's context space and ensures critical tool accuracy during extended reasoning. Experiments on the Earth-Bench benchmark show RS-Claw achieves an 86% input token compression ratio and outperforms Flat and RAG baselines in complex reasoning tasks.

Key takeaway

For Computer Vision Engineers developing remote sensing agents, RS-Claw's active tool exploration paradigm offers a significant advancement over passive selection methods. You should consider implementing hierarchical skill trees and dynamic tool description loading to improve context efficiency and ensure critical tool accuracy in long-horizon tasks. This approach can lead to substantial input token compression and enhanced reasoning capabilities for your MLLM-based agents.

Key insights

Active tool exploration via hierarchical skill trees improves remote sensing agent performance and context efficiency.

Principles

• Agents should actively explore tool spaces.
