SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Feature specification translates a PRD from what to build into exactly how it should behave. Its primary reader is the Development agent, so without a precise spec interpretation can drift into implementation details during development rather than during planning.

Core Features & Use Cases

  • Use a structured pattern to write unambiguous feature specs that cover API contracts, UI behavior, and state definitions.
  • Specify states (Default/Initial, Loading, Empty, Populated, Error, Disabled) to remove ambiguity in UI and backend behavior.
  • Define boundaries and explicit out-of-scope items to prevent scope creep and ensure clear acceptance criteria.

Quick Start

Copy the Feature Spec Template and fill in the Overview, Out of Scope, UI, and API sections to convert a PRD into an implementation-ready spec.

FAQPage Schema
How do I convert a PRD into an implementation-ready feature spec?▼

Converting a PRD into a feature spec requires translating product requirements into a structured template covering overview, boundaries, explicit out-of-scope items, UI states, and API patterns for unambiguous guidance.

What UI states should be defined in feature specifications to remove ambiguity?▼

Feature specifications should define Default, Loading, Empty, Populated, Error, and Disabled UI states to remove ambiguity in frontend behavior and backend responses during development.

How do you define explicit out-of-scope boundaries in API contracts and UI behavior?▼

Defining explicit out-of-scope boundaries in API contracts and UI behavior involves listing excluded features and non-target workflows within the spec template to prevent scope creep and ensure clear acceptance criteria.

Can I use a structured template for writing acceptance criteria for development teams?▼

Yes, you can use a structured feature spec template to write testable acceptance criteria, ensuring development teams receive precise, implementation-ready guidance rather than ambiguous product requirements.

Why does implementation drift occur without precise feature specs?▼

Implementation drift occurs without precise feature specs because developers interpret ambiguous PRDs during coding rather than planning, leading to inconsistent UI behavior and undocumented API contract patterns.
