Toward Instructions-as-Code: Understanding the Impact of Instruction Files on Agentic Pull Requests

arXiv:2606.13449v1 Announce Type: cross Abstract: AI-agents (e.g., GitHub Copilot) collaborate as teammates in different software engineering tasks, including code generation proposed through pull requests (Agentic-PRs). For better agent efficiency, developers create instruction files that guide the AI-agents, including how to navigate the project, locate the right components, run tests, respect best practices, and more. In this paper, we investigate the relationship between the creation of these instructions and the performance of AI-agents in creating better pull requests, which have a highe

Why this matters
Why now

The proliferation of AI agents in software development necessitates new methods for guiding their performance and integration into existing workflows.

Why it’s important

This research provides insights into how developers can effectively interact with and improve the output of AI agents, directly impacting software development efficiency and quality.

What changes

The focus shifts from merely using AI agents to actively engineering their operational parameters through dedicated instruction files, formalizing the 'instructions-as-code' paradigm.

Winners
  • · Software developers
