## Summary  
Spatial reasoning—the ability to understand where objects are, how they relate, and how they move in three‑dimensional space—remains a bottleneck for vision‑language models (VLMs). Existing tool‑augmented agents either commit to a full analysis strategy via single‑pass code execution or rely on rigid structured tool calls that limit flexibility. The authors introduce **SpatialClaw**, a training‑free framework that treats code as the action interface, allowing agents to compose and adapt perception results step by step.

## Key Contributions  
- [Finding 1] Current spatial agents are constrained by either monolithic code execution or inflexible structured tool calls, which hinder open‑ended 3D/4D reasoning.  
- [Finding 2] SpatialClaw replaces these interfaces with a stateful Python kernel that lets the VLM‑backed agent write one executable cell per step, preserving all prior inputs and outputs.  
- [Finding 3] On twenty benchmarks spanning static and dynamic spatial tasks, SpatialClaw achieves an average accuracy of **59.9 %**, surpassing recent spatial agents by **+11.2 points** across six VLM backbones from two model families without any adaptation.

## Methodology  
The authors designed a training‑free pipeline where the agent’s perception module feeds input frames into a pre‑loaded Python kernel equipped with geometry and perception primitives. The kernel maintains state of both visual observations and textual reasoning, enabling each new cell to conditionally execute based on all previous outputs. This approach decouples the VLM from tool selection, allowing free composition of operations.

## Results  
SpatialClaw’s performance is measured across a diverse set of twenty spatial‑reasoning benchmarks. The framework consistently reaches **59.9 %** average accuracy, which is an 11.2‑point improvement over the best existing agents. These gains hold for six VLM backbones belonging to two distinct model families, demonstrating robustness without benchmark‑ or model‑specific tuning.

## Significance  
By treating code as a flexible action interface, SpatialClaw unlocks open‑ended spatial reasoning that can adapt to novel tasks and intermediate observations. This work provides a scalable, reusable foundation for future agentic perception systems, reducing reliance on costly retraining of vision‑language models.
