TL;DR: AI coding assistants can increase developer productivity by up to 55%, but Sonar argues that the same velocity also drives more duplication, review bottlenecks, and technical debt unless automated verification keeps pace. The core issue is not AI quality alone, but unmanaged change volume, which turns speed gains into long-term delivery and security drag.
Editorial analysis by NHI Mgmt Group, based on content published by Sonar: “The inevitable rise of poor code quality in AI-accelerated codebases”.
Key questions
Q: What breaks when AI agents can make code changes faster than humans can review them?
A: Manual review stops being a meaningful control if it cannot keep pace with change volume.
Q: Why does AI-generated code create more technical debt so quickly?
A: AI increases output volume and repetition, so insecure patterns can spread before teams notice them.
Q: What are the signs that AI-generated code is overwhelming controls?
A: Common signals include larger pull requests, rising review time, more duplicated code, more debugging effort, and a growing gap between feature velocity and code quality.
Practitioner guidance
- Implement automated quality gates at merge time Require static analysis, duplication checks, and architectural consistency checks before code can be merged, especially for AI-generated pull requests.
- Limit review scope to risk-based changes Prioritise human review on high-risk code paths, security-sensitive modules, and large generated diffs rather than treating every AI-assisted change the same.
- Measure AI-induced change volume separately Track pull request size, duplication rate, bug escape rate, and review time for AI-assisted versus human-authored code so the governance impact is visible.
Bottom line: AI coding assistants can raise output quickly, but the governance challenge is that change volume grows faster than human review capacity.

AI coding velocity creates a governance problem before it creates a quality problem: once machine-generated changes outpace human review, the control point moves from developer judgment to automated verification. That is a software assurance shift, but it also affects identity and workflow governance because the system accepting the change becomes part of the trust boundary. Practitioners should treat AI-assisted development as a managed acceleration model, not a simple productivity feature.
A few things that frame the scale:
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
- AI-related credential leaks surged 81.5% year-over-year in 2025, with the surrounding AI infrastructure leaking 5x faster than core LLM providers, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: How should security teams control AI-assisted coding without slowing developers down?
A: Put policy into the IDE so security guidance appears during code creation, not after commit. Teams should use safe defaults, prompt shaping, and low-friction remediation paths. The goal is to reduce insecure output while preserving developer flow, because delayed controls create rework and encourage bypasses.
