TL;DR

This collection provides a structured approach for product managers to navigate the transition toward probabilistic AI models. It focuses on defining defensible strategies through verticalization and proprietary data while designing interfaces that manage user intent and agency.

The skills bridge the gap between strategic planning and execution, offering guidance on identifying high-value customer profiles and using AI coding tools to build functional prototypes from natural language or visual mocks.

Install writing-prds for Claude Code

Installs: One selected skill folder (writing-prds) in the current project's .claude/skills/ directory; this does not install the complete 76-skill collection. · Claude Code

Before you start
  • Git must be available for the documented clone command.
  • The project must have a .claude/skills/ destination directory.

Run from: The project root where .claude/skills/ is located

  1. From the project root, run this terminal code unit to clone the repository and copy the writing-prds folder into the project's .claude/skills/ directory.

Give it something to do.

Suggested first task

Run a focused backlog audit

Uses roadmap-prioritization

  • Current backlog or a short list of candidate initiatives
  • Available churn data, support themes, customer-request evidence, or strategic goals
  • The team's available time or fixed appetite

Check the repository for this skill’s setup.

Use the roadmap-prioritization skill to review my current backlog. Categorize the items by source, identify which requests lack quantitative validation, and ask me what fixed appetite or time-box applies to the leading initiative. Keep this first pass focused on the most important items rather than drafting a complete roadmap.
Suggested first task

Diagnose the product strategy crux

Uses defining-product-strategy

  • Product and company context
  • Current goals and observed problems
  • Target customers and market context

Check the repository for this skill’s setup.

Use the defining-product-strategy skill to help me identify the single high-stakes challenge holding this product back. Based on the context I provide, distinguish that challenge from goals or symptoms, then propose a concise diagnosis and ask the key questions needed to validate it.
Suggested first task

Define an initial retention measurement plan

Uses retention-engagement

  • Product description and target users
  • Available activation, cohort-retention, and churn data
  • Current definition of an active user

Check the repository for this skill’s setup.

Use the retention-engagement skill to identify the action that represents core product value and outline a basic cohort-based retention measurement plan. Ask me when the retention curve flattens and flag any activity metrics that may be noise rather than evidence of value.
