SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps teams replace vague feature ideas with explicit, testable, and well-scoped specifications—reducing misunderstandings, missing requirements, and late-stage rework.

Core Features & Use Cases

  • Scope control: defines in-scope/out-of-scope boundaries, assumptions, MVP vs full vision, and work breakdowns to prevent scope creep.
  • Requirements clarity: writes functional vs non-functional requirements, state requirements without prescribing solutions, and expresses them as user stories for shared understanding.
  • Objective acceptance & planning: formulates acceptance criteria (including edge cases and Given-When-Then), establishes definition of done, and aligns on success metrics.
  • Prioritization with justification: applies MoSCoW, Kano, RICE, and value-vs-effort methods to make tradeoffs defensible.
  • Change governance: documents impact assessments, enforces formal change requests, maintains deferred-item logs, and versions specs.
  • Technical integration readiness: guides API contract, system context, data model/schema, error handling, performance, and security specification.

Quick Start

Use the feature-spec skill to draft a complete PRD by applying the rules for scope boundaries, measurable requirements, and testable acceptance criteria.

Frequently Asked Questions about feature-spec

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write a feature specification that prevents scope creep?▼

To prevent scope creep, write feature specifications that define in-scope and out-of-scope boundaries, document assumptions, and separate MVP requirements from the full product vision. Including a structured work breakdown ensures the feature specification maintains strict scope control.

What is the best way to structure acceptance criteria in a PRD?▼

The best way to structure acceptance criteria in a PRD is using Given-When-Then formatting to cover edge cases. High-clarity PRDs formulate testable acceptance criteria that align with measurable success metrics and a clear definition of done.

How do you prioritize requirements using MoSCoW and RICE methods?▼

Prioritize requirements using MoSCoW and RICE methods by evaluating value versus effort to make tradeoffs defensible. Applying these prioritization frameworks to your requirements ensures objective justification for feature inclusion and release staging.

How do I manage change requests for technical API contracts and data schemas?▼

Manage change requests for API contracts and data schemas by documenting impact assessments and enforcing formal change governance. Versioning your technical specifications ensures system context changes are traceable and controlled throughout the lifecycle.

When do I need to specify non-functional requirements for system context?▼

You need to specify non-functional requirements for system context when defining performance, error handling, and security specifications. Separating functional from non-functional requirements ensures the technical integration readiness of your data model and API contracts.
