Easy Starter Product Kit

PRD Template Design Brief Spec Driven AI Agent Ready License MIT

"What do we build for, if not to lessen each other’s hardship?"

A starter kit for turning product ideas into clear PRDs, design briefs, specs, plans, and implementation-ready tasks.

Before the first line of code, this repository helps your team answer the questions that actually shape a product:

• What are we building?
• Who are we building it for?
• Why does it matter?
• What does success look like?
• What should the designer, developer, QA, and AI agents follow?

The goal is simple: Make the docs the single source of truth, not scattered chats, vague memories, or hidden assumptions.

Most projects fail because the team starts building before the problem, user, scope, edge cases, and success criteria are clear.

Easy Starter Product Kit gives you a repeatable workflow for moving from a raw idea to a product-ready specification. It is useful for:

• Solo founders
• Freelancers building client products
• SaaS and MVP development
• Startup teams
• Product designers and engineers
• AI-first development workflows
• Teams that want predictable and maintainable execution

• Opportunity scorecards and validation plans
• Product One-Pagers
• User Research Notes
• Personas and JTBD docs
• PRDs
• Design Briefs
• UX/UI Specifications
• Technical Briefs
• API and Data Specs
• Feature Specs
• Implementation Plans
• Test-first Task Lists
• Launch Plans
• Business models and pricing hypotheses
• Figma file and prototype plans
• Post-launch Learning Notes

Every step reduces uncertainty and creates a better foundation for the next stage.

templates/ Product, design, and engineering templates

examples/ Filled examples for faster understanding
.github/ Issue and pull request templates

1. Clone or use this repository as a template.
2. Fill the Product One-Pager first.
3. Use the prompts in prompts/ to clarify missing context.
4. Write the PRD and Design Brief.
5. Create a new feature folder under specs/features/001-feature-name/.
6. Copy the files from specs/_feature-template/ into that feature folder.
7. Turn the feature spec into plan.md and tasks.md.
8. Ask your coding agent to implement only what is written in the spec and tasks.
9. Make every pull request reference the related requirement IDs.
10. After release, document what you learned and update the source of truth.

Use stable IDs across PRDs, specs, tasks, commits, pull requests, and test cases.

This makes every implementation decision traceable back to the product intent.

This repo is designed to work well with tools like coding agents, AI IDEs, and spec-driven development workflows.

A good rule:

Do not ask the agent to "build the app."
Ask the agent to implement a specific feature spec with clear requirements, acceptance criteria, tests, and constraints.

That small shift makes AI-first development much more predictable, maintainable, and reviewable.
