[counterintuitive] AI coding tools reduce the need for specifications
Invest more in precise specifications and invariants when using AI; ambiguity is amplified, not resolved, and the model will confidently fill gaps with plausible-looking but wrong assumptions.
Journey Context:
There is a temptation to skip detailed specs because the AI can 'figure it out.' In practice, LLMs are ambiguity amplifiers: when requirements are underspecified, they default to the most common pattern in their training data, which may not match your system's constraints. The resulting code looks reasonable and often passes smoke tests while violating business rules or security policies. The evidence from requirements-engineering studies suggests that AI output quality tracks specification quality more steeply than human output does. The fix is countercyclical: spend the saved implementation time on sharper specs, invariants, and acceptance criteria.
