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.
NHIMG editorial — based on content published by Sonar: AI coding velocity creates technical debt faster than manual review
By the numbers:
- 55%, -assisted coding can raise developer productivity by up to 55%, according to Sonar, but that same speed can overload review capacity and accumulate quality liabilities.
Questions worth separating out
Q: What breaks when AI coding tools are trusted without strong verification?
A: What breaks first is consistency.
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: How can security teams tell whether code verification is keeping pace with AI output?
A: Look for smaller pull requests, stable review times, lower duplication rates, and declining defect escape rates.
Practitioner guidance
- Embed automated quality gates in every merge path Require static analysis, duplication checks, and complexity thresholds to pass before code can merge into protected branches.
- Classify identity and secrets code as high-risk Tag authentication, authorisation, token handling, and secrets management code for enhanced review because defects in these paths can weaken access control across the whole platform.
- Shrink pull requests to reduce reviewer overload Set practical size limits and encourage smaller changes so reviewers can validate logic, security impact, and regression risk without missing defects hidden in large AI-generated diffs.

AI coding assistants create governance debt faster than they create productivity gains. The article's central claim is that velocity without verification shifts risk downstream rather than eliminating it. For security and identity teams, that matters because access logic, token handling, and permission checks are often buried inside rapidly changing application code. Organisations should treat AI-assisted development as a control problem, not just an engineering efficiency story.
A question worth separating out:
Q: Should organisations use AI-generated code in security-sensitive workflows?
A: Yes, but only with strict controls around review, testing, and ownership. For security-sensitive workflows, the key question is not whether AI can generate code, but whether the organisation can prove its behaviour, maintainability, and failure modes. Without that proof, the delivery gain is offset by hidden risk.
