Beyond the'Diff': Addressing Agentic Entropy in Agentic Software Development

2026-03-03

AI Summary

This work addresses the systematic divergence between agent behavior and architectural intent—termed “agent entropy”—that emerges during rapid development of autonomous coding agents. Conventional approaches relying on code diffs or local explainable AI methods struggle to capture such global cognitive drift. To bridge this gap, the paper introduces the first process-oriented explainability framework, integrating three core mechanisms: consistency seed injection, runtime reasoning monitoring, and a causal graph interface. This framework traces decision evolution across temporal, tool-invocation, and architectural boundaries, generating telemetry at the level of intended behavior. Treating cognitive drift as critically as code quality, the approach balances structural transparency for non-expert users with contextual richness for developers, uncovering latent insights obscured by functional success in “ambient programming” and enabling low-overhead, high-fidelity agent behavior supervision.

Abstract

As autonomous coding agents become deeply embedded in software development workflows, their high operational velocity introduces a critical oversight challenge: the accumulating divergence between agentic actions and architectural intent. We term this process agentic entropy: a systemic drift that traditional code diff-based and HCXAI methods fail to capture, as they address local outputs rather than global agentic behaviour. To close this gap, we propose a process-oriented explainability framework that exposes how agentic decisions unfold across time, tool calls, and architectural boundaries. Built around three pillars (conformity seeding, reasoning monitoring, and a causal graph interface) our approach provides intent-level telemetry that complements, rather than replaces, existing review practices. We demonstrate its relevance across two user profiles: lay users engaged in vibe coding, who gain structural visibility otherwise masked by functional success; and professional developers, who gain richer contextual grounding for code review without increased overhead. By treating cognitive drift as a first-class concern alongside code quality, our framework supports the minimum level of human comprehension required for agentic oversight to remain substantive.
