RS-Claw: Progressive Active Tool Exploration via Hierarchical Skill Trees for Remote Sensing Agents
Summary
RS-Claw introduces a novel remote sensing (RS) agent architecture that redefines tool selection from a passive to an active exploration paradigm, addressing context space deficits and tool omission in existing multi-modal large language model (MLLM) agents. Current methods, such as "Flat" (full tool registration) and "RAG" (retrieval-augmented generation), struggle with massive, heterogeneous RS tool ecosystems, leading to context overload or incomplete tool coverage. RS-Claw leverages "Skill encapsulation technology" to hierarchically structure tool descriptions, enabling agents to make on-demand sequential decisions. This involves initially selecting relevant skill branches based on tool summaries, then dynamically loading detailed descriptions for precise invocation. Experiments on the Earth-Bench benchmark demonstrate RS-Claw's superior performance, achieving up to an 86% input token compression ratio and outperforming Flat and RAG baselines across various complex reasoning evaluations, particularly with less capable models like Qwen3-32b.
Key takeaway
For Computer Vision Engineers developing remote sensing agents with extensive tool libraries, RS-Claw offers a robust solution to overcome context bottlenecks and improve task accuracy. You should consider adopting a hierarchical skill tree and progressive disclosure mechanism to enable your agents to actively explore and load tools on demand. This approach significantly reduces token consumption (up to 86% compression) and enhances reasoning stability, especially for long-horizon tasks, without requiring model fine-tuning.
Key insights
Active, hierarchical tool exploration significantly improves remote sensing agent performance and context efficiency.
Principles
- Tool acquisition should be an active, task-driven process.
- Hierarchical structuring of tools reduces semantic noise.
- On-demand loading optimizes context space and tool hit rates.
Method
RS-Claw constructs a three-tier hierarchical skill tree (Skill Summary, Tool Catalog, Tool Documentation) and employs a progressive disclosure strategy, allowing agents to dynamically explore and load tool information as needed within a unified sequential decision-making framework.
In practice
- Implement hierarchical skill trees for large tool libraries.
- Use progressive disclosure to manage context load.
- Prioritize active tool exploration over passive retrieval.
