App Specification Guide
An app specification (or PRD) describes what you are building, for whom, and how it should behave — before implementation. Strong specs reduce ambiguity for developers and AI coding assistants.
What belongs in a spec?
- Overview — problem, users, success metrics
- Features & user flows — screens, actions, edge cases
- Technical — stack, APIs, data models, integrations
- Non-functional — security, performance, SEO/GEO launch plan
- Prompts & exports — ready-to-use instructions for AI IDEs
Why specs improve AI-assisted development
Without a spec, every chat message re-explains context. With a spec, you point tools at a single document — saving tokens and preventing contradictory features. Teams report fewer refactors and faster onboarding.
