arXiv:2607.01903v1 Announce Type: new Abstract: LLM-integrated applications blend natural language prompts with program code, and much of their runtime behavior originates in the prompt layer rather than in the code itself. Existing complexity metrics, however, operate solely at the code level and therefore overlook this behavioral logic entirely. We present HECATE, the first tool designed to assess complexity in both the prompt and code layers of such applications. Central to HECATE is Prompt-as-Specification, a Hoare-logic-inspired formalism that interprets every prompt as a specification of
The rapid deployment of LLM-integrated applications highlights a critical gap in existing software development and assurance methodologies, making new complexity metrics essential now.
This development allows for better understanding, management, and security of increasingly complex AI-driven systems, which are becoming central to many workflows and products.
Traditional software complexity metrics, focused solely on code, are now insufficient for evaluating LLM-integrated applications, requiring new tools that account for prompt-layer logic.

- · Organizations relying solely on legacy code analysis tools
Developers will gain better tools to diagnose and manage the complexity of their LLM-integrated applications.
Improved understanding of prompt complexity could lead to more robust, secure, and predictable AI systems, accelerating agent development.
Formal verification and testing standards may emerge for prompt engineering, blurring lines between software and AI behavior assurance.
