SWE-Pruner Breaks the Context Wall: How to Slash AI Coding Agent Costs by 54%

Breaking the “Context Wall” for Code Agents: A Deep Dive into SWE-Pruner’s Adaptive Context Pruning In the current landscape of software development, Large Language Model (LLM)-based agents are demonstrating remarkable capabilities, navigating codebases, running tests, and submitting patches end-to-end. However, as these capabilities grow, a critical “Context Wall” problem has emerged: the accumulation of long interaction contexts within LLMs is driving up API costs and introducing severe latency. Existing compression methods often compromise code syntax or discard critical debugging details. This article explores SWE-Pruner, a framework that mimics human “selective skimming” to provide task-aware, adaptive context pruning for coding agents. …
