SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Requirements ambiguity often leads to misaligned expectations, rework, and late-stage changes. This skill provides a structured approach to capture, organize, and validate requirements so that teams share a common understanding.

Core Features & Use Cases

EARS-based requirements: Use WHEN/IF/WHILE/WHERE to express testable requirements.
User stories to acceptance criteria: Convert ideas into well-scoped stories and measurable criteria.
Validation guidance: Checklists and templates for completeness, correctness, and traceability.
Non-functional considerations: Include performance, reliability, security considerations.
Playbook and templates: Step-by-step workflows to drive spec-driven development.

Quick Start

Ask clarifying questions to gather context and objectives
Create a requirements document in specs/ using the templates and examples in EARS_REFERENCE.md, VALIDATION.md, and EXAMPLES.md
Use the SKILL frontmatter to capture metadata and the body to guide the workflow

FAQPage Schema

How do I write testable requirements from vague software ideas?▼

Convert user stories into measurable acceptance criteria using EARS syntax. This approach enforces testability, includes non-functional considerations like performance and security, and provides validation checklists to ensure completeness.

What is EARS formatting for software requirement specification?▼

EARS is a syntax using WHEN/IF/WHILE/WHERE keywords to write unambiguous requirements. It transforms unclear feature definitions into precise, testable specifications, preventing misaligned expectations and late-stage rework.

How do I create acceptance criteria from user stories?▼

Convert user stories into well-scoped narratives and measurable acceptance criteria using EARS syntax. This includes checking for completeness, correctness, and traceability while incorporating non-functional considerations like performance and security.

How do I validate software requirements for completeness and traceability?▼

Validate software requirements using provided checklists and templates to ensure completeness, correctness, and traceability. This structured approach confirms specifications are prepared for downstream design and testing phases.

Does this requirements engineering approach support non-functional requirements?▼

Yes, this approach supports non-functional requirements by explicitly including performance, reliability, and security considerations. It integrates these into the overall EARS specification to ensure comprehensive validation across the feature lifecycle.
