Paper argues AI agents mark a paradigm shift in software engineering
A paper by Zhenfeng Cao argues that AI agents — where LLMs dynamically generate and discard code as ephemeral tooling — represent a fundamental restructuring of software engineering, not merely an incremental improvement.
Score breakdown
The paper formalizes a conceptual framework — including the new discipline of "Agentic Engineering" and the AaaS category — that attempts to give researchers and practitioners a structured vocabulary for understanding how LLM-driven agents differ fundamentally from traditional software systems.
- 01Author Zhenfeng Cao argues AI agents represent a fundamental restructuring of software engineering, not an incremental improvement.
- 02The paper distinguishes traditional software (code as decision-logic carrier) from agentic systems (code as ephemeral tooling for an LLM reasoning loop).
- 03It introduces the concept of 'Agentic Engineering' as an emergent discipline distinct from software engineering in its core object of study, control model, and human role.
Zhenfeng Cao's paper challenges the foundational premise of software engineering — that human engineers decompose problems, encode decision logic into static code, and manually adapt it as requirements change. The paper argues that AI agents, where LLMs serve as the primary reasoning engine and code is generated and discarded dynamically as an instrumental resource, represent a fundamental restructuring of the software paradigm rather than an improvement within it. Using first-principles analysis of complexity scaling, the paper formalizes the core distinction: in traditional software, code is the carrier of decision logic; in agentic systems, code is ephemeral tooling subordinate to an LLM-driven reasoning loop.
The paper traces a historical arc from licensed software through SaaS to what it calls Agent-as-a-Service (AaaS), framing each transition as a shift that moved additional complexity away from end-users.
The paper traces a historical arc from licensed software through SaaS to what it calls Agent-as-a-Service (AaaS), framing each transition as a shift that moved additional complexity away from end-users. From this, it introduces "Agentic Engineering" as an emergent discipline with a distinct object of study, control model, and human role compared to classical software engineering. Evidence is drawn from recent benchmarks — SWE-bench Verified, EvoClaw, and LangChain's multi-agent coordination studies — to illustrate both the transformative potential and the present limitations of agentic systems. The paper concludes with a four-stage roadmap toward self-evolving agent ecosystems and concrete recommendations for practitioners navigating the transition.
