Definition
Technical debt is the implied cost of future rework caused by choosing expedient solutions over sustainable design — including duplicated code, neglected refactoring, and shallow error handling that accumulates maintainability burden over time.
Key Points
- 2026-07 GitClear study: AI-assisted commits (~25% of volume) correlate with +81% duplication, −74% legacy refactoring, +47% obfuscation patterns (gitclear)
- LLMs tend to generate new code/packages rather than reuse existing modules — violating DRY in practice
- Complements building-to-the-test research on benchmark gaming vs. maintainability degradation
- Mitigation: stricter code review, refactoring discipline, dependency hygiene when using ai-coding-tools
