Write A Prd

Create a PRD through user interview, codebase exploration, and module design, then write it to a local markdown file. Use when user wants to write a PRD, create a product requirements document, or plan a new feature.

File contents

This skill will be invoked when the user wants to create a PRD. You may skip steps if you don't consider them necessary.

Ask the user for a long, detailed description of the problem they want to solve and any potential ideas for solutions.
Explore the repo to verify their assertions and understand the current state of the codebase.
Interview the user relentlessly about every aspect of this plan until you reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one.
Sketch out the major modules you will need to build or modify to complete the implementation. Actively look for opportunities to extract deep modules that can be tested in isolation.

A deep module (as opposed to a shallow module) is one which encapsulates a lot of functionality in a simple, testable interface which rarely changes.

Check with the user that these modules match their expectations. Check with the user which modules they want tests written for.

Once you have a complete understanding of the problem and solution, use the template below to write the PRD. The PRD should be written to a local markdown file in the repository.

Problem Statement

The problem that the user is facing, from the user's perspective.

Solution

The solution to the problem, from the user's perspective.

User Stories

A LONG, numbered list of user stories. Each user story should be in the format of:

As an , I want a , so that

This list of user stories should be extremely extensive and cover all aspects of the feature.

Implementation Decisions

A list of implementation decisions that were made. This can include:

The modules that will be built/modified
The interfaces of those modules that will be modified
Technical clarifications from the developer
Architectural decisions
Schema changes
API contracts
Specific interactions

Do NOT include specific file paths or code snippets. They may end up being outdated very quickly.

Testing Decisions

A list of testing decisions that were made. Include:

A description of what makes a good test (only test external behavior, not implementation details)
Which modules will be tested
Prior art for the tests (i.e. similar types of tests in the codebase)

Out of Scope

A description of the things that are out of scope for this PRD.
