What spec-anchored development means
The specification is a living source of truth for user journeys, data, permissions, integrations, constraints and acceptance criteria. It is updated as decisions change, so implementation stays connected to the intended product.
Where AI adds speed
AI-assisted implementation can accelerate exploration and iteration. Human judgement still determines the architecture, user experience, security boundaries and whether the result meets the brief.
What the specification contains
A practical specification records the problem, target users, version-one scope, key screens, business rules, failure states and examples of expected behaviour. It also makes exclusions and unresolved decisions visible.
How we verify a build
We review the implemented journeys against the agreed criteria, exercise important error cases and resolve gaps before release. Changes are judged against the product model rather than an isolated screenshot.
How the product evolves
Feedback can change the specification. We record the decision, assess its effect on existing behaviour and build the next increment with the same requirements and verification discipline.
Questions about spec-anchored vibe coding
Is this suitable for professional software?
AI-assisted development can support professional delivery when requirements, review, testing and operational responsibilities are properly addressed. The approach is selected to fit the project.
Does a specification prevent fast iteration?
No. It preserves the decisions that matter while making changes deliberate. The document evolves with the product.
