Specification Portability Across LLM Development Agents: Cross-Agent Compatibility in Specification-Driven Software Migration

L5 · ResearcherResearcharXiv· 8/21/2026

Critical for ML engineers working on multi-agent systems and software migration pipelines.

AI Summary

Researchers demonstrate significant cross-agent degradation in LLM specification portability, showing Oracle-to-PostgreSQL migration specifications aren't agent-neutral artifacts.

Excerpt

This paper investigates cross-agent specification portability using Oracle-to-PostgreSQL migration as a controlled software transformation task. The study combines two experimental stages. First, a specification-first migration pipeline was evaluated on 1,006 PL/SQL files, of which 623 were successfully regenerated and 380 generated scripts executed successfully in PostgreSQL 16. Second, cross-agent experiments were conducted on a dataset of 1,802 Oracle scripts with corresponding PostgreSQL imp
