SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prevents ad hoc, inconsistent feature design by guiding the creation of a single, review-ready design.md that captures terminology, interface contracts, implementation steps, and test plans so downstream implementation and acceptance are aligned and repeatable.

Core Features & Use Cases

  • Evidence collection: instructs reading architecture docs, relevant code, and archives before drafting to ensure proposals align with existing systems.
  • Terminology grep: mandates searching the codebase and docs to avoid naming collisions and ambiguous terms.
  • Interface-first examples: requires concrete input→output examples for APIs and component props/events to make contracts testable.
  • One-shot draft + review: produces a complete draft (status=draft) for a single overall review, then upgrades to approved and extracts checklist.yaml.
  • Checklist generation & validation: extracts actionable steps and checks into checklist.yaml and validates YAML syntax for implementers.

Quick Start

Draft a complete design.md for the target feature by reading architecture docs, performing terminology grep to avoid collisions, writing concrete interface examples and test design, and export a validated checklist.yaml for implementation.

Frequently Asked Questions about easysdd-feature-design

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

FAQPage Schema
How do I draft a feature design document that is ready for engineering review?

To draft a review-ready feature design document, you collect evidence from architecture docs and code, perform terminology grep for naming collisions, define interface contracts, and write test designs. This produces a structured design.md with YAML frontmatter for downstream alignment.

What is the best way to generate an implementation checklist from a software feature design?

Generating an implementation checklist from a software feature design involves extracting actionable steps and test criteria from a finalized design document. The process parses approved design content and exports a validated checklist.yaml file for implementers to track progress.

How do you avoid terminology collisions when designing new software features?

To avoid terminology collisions when designing new software features, you perform a terminology grep across the codebase and existing architecture docs. This identifies conflicting naming conventions and ambiguous terms before drafting the feature design document.

Why do feature design documents need concrete interface contract examples?

Feature design documents need concrete interface contract examples to make API inputs, outputs, and component props testable. Defining interface contracts first ensures downstream implementation and acceptance criteria remain aligned and repeatable across the engineering team.

Can I use a single feature design workflow for both drafting and checklist extraction?

Yes, you can use a single feature design workflow for both drafting and checklist extraction. The process produces a complete design.md with status set to draft for initial review, then upgrades to approved and extracts a validated checklist.yaml for implementation.

What should a software feature design document include for test design and implementation?

A software feature design document should include test design sections, staged implementation steps, and YAML frontmatter with metadata tags. These components ensure the test plans and progression steps are actionable and validated for implementers.
