SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Harness-planner converts a concise project brief into a thorough product specification, enabling a builder-led workflow to sprint toward a shipped product.

Core Features & Use Cases

  • Scales a 1-4 sentence prompt into a full product spec, including overview, architecture, design direction, features, and sprint plans.
  • Supports delta/spec updates for existing projects using CODEBASE_AUDIT.md, preserving solid architecture while guiding new work.
  • Integrates with the .harness workflow to produce .harness/PRODUCT_SPEC.md and update .harness/config.yaml with stack choices.

Quick Start

Provide a 1-2 sentence project brief to begin, and the planner will output a complete Product Spec ready for review.

FAQPage Schema
How do I turn a short project prompt into a full product specification?

You can turn a short project prompt into a full product specification by processing it through a planner that expands the brief into overview, architecture, design direction, features, and sprint plans. It outputs a production-ready spec file for review.

Can I update an existing project specification without overwriting the current architecture?

Yes, you can update an existing project specification without losing solid architecture by running a codebase audit. It generates delta spec updates that preserve your current structure while guiding new work through revised sprint plans.

What do I need to generate sprint plans from a product brief?

To generate sprint plans from a product brief, you only need a one to two sentence project description. The planner scales this concise input into structured sprint plans alongside architecture and design direction without requiring prescriptive implementation details.

Does the harness workflow support automatic configuration updates for a chosen tech stack?

Yes, the harness workflow supports automatic configuration updates by writing the generated product specification to a designated directory and updating the configuration file to reflect your chosen stack choices and planning principles.

What is included in a production-ready product spec generated from a brief?

A production-ready product spec generated from a brief includes a project overview, architecture guidelines, design direction, feature outlines, and structured sprint plans. It enforces frontmatter requirements to maintain consistent documentation standards.
