Product Playbook for Agentic Coding

A Claude Code plugin that provides a structured workflow for product-driven agentic software development.

Overview

This plugin implements a systematic approach to building software with AI assistance. The full evidence pipeline:

Foundations → Research → Synthesis → Prioritization → PRD → Tech Plan → Tasks → Delivery → Learnings
     ↑                                                                                        |
     └────────────────────────── learnings feed back ─────────────────────────────────────────┘

The Four Phases

1. Product Discovery — Build strategy foundations, synthesize research, prioritize opportunities, and define what to build
2. Solution Planning — Design how to build it with architecture, sequencing, and task breakdown
3. Delivery — Execute work systematically with quality gates
4. Retrospective — Capture learnings that improve both documentation and the workflow itself

The Evidence Pipeline

Not every project needs every step. A small feature might start at PRD. A new product strategy starts at Foundations.

Step	Command	What It Produces	When to Use
Foundations	/playbook:foundations	Mission, Vision, Personas, Engagement Framework	New product or strategy work
Research Synthesis	/playbook:research-synthesis	Opportunities narrative from quant + qual + taste research	After conducting research
Prioritization	Use resources/templates/prioritization.md	Ranked ideas with transparent scoring	When choosing between multiple opportunities
Product Requirements	/playbook:product-requirements	Agent-ready PRD	Before building any feature
Tech Plan	/playbook:tech-plan	Architecture, sequencing, technology decisions	Before implementation
Tasks	/playbook:tasks	Specific, actionable tasks with acceptance criteria	Before starting work
Delivery	/playbook:work	Implemented features	During implementation
Learnings	/playbook:learnings	Documented insights that improve future work	After any work session

Installation

From GitHub (Recommended)

# Add the GitHub repository as a marketplace
/plugin marketplace add daviswhitehead/product-playbook-for-agentic-coding-plugin

# Install the plugin
/plugin install product-playbook-for-agentic-coding@product-playbook-marketplace

From Local Path (Development)

# Add the local plugin directory as a marketplace
/plugin marketplace add /path/to/product-playbook-for-agentic-coding-plugin

# Install the plugin
/plugin install product-playbook-for-agentic-coding@product-playbook-marketplace

Updating the Plugin

This plugin uses a marketplace-embedded structure (plugin source is inside the marketplace repo). The "Update now" button in the plugin UI won't work directly—this is expected behavior for this type of plugin architecture.

To update to the latest version:

1. Update the marketplace (pulls latest from GitHub):

   /plugin → Marketplaces tab → select "product-playbook-marketplace" → Update now
   

2. Reinstall the plugin:

   /plugin → Installed tab → select the plugin → Uninstall
   /plugin → Marketplaces tab → select marketplace → Install
   

Note: The "Local plugins cannot be updated remotely" message appears because the plugin uses a relative path source within the marketplace. This is the same pattern used by many plugins in Anthropic's official marketplace.
