Analyzing AI Agent Performance on TypeScript Tasks: A Deep Dive

By G2i AI TeamLate 2025/ 3 Min read/ Research

Introduction

As AI coding agents become increasingly sophisticated, understanding their failure modes is essential to improving them. G2i is launching research examining why AI coding agents struggle most with TypeScript repositories within the Multi-SWE benchmark framework.

Research Focus

The initiative targets four primary areas:

Root Cause Analysis

Investigates the fundamental reasons agents fail to solve TypeScript tasks correctly, whether due to type system misunderstandings, incorrect dependency resolution, module system confusion, or other language-specific challenges.

Pattern Recognition

Identifies recurring error patterns, enabling targeted interventions and training approaches that address these systematic errors.

Loop Detection

Examines scenarios where agents enter unproductive loops, repeatedly attempting similar unsuccessful approaches.

Trajectory Optimization

Evaluates how efficiently agents search the solution space, comparing successful trajectories to identify characteristics of optimal problem-solving approaches.

Context

While AI agents demonstrate promise across programming languages, TypeScript and JavaScript consistently exhibit some of the lowest resolution rates. This performance disparity represents an opportunity for understanding fundamental system limitations through empirical trajectory analysis rather than theoretical speculation.
