Pureinn Documentation
/plugin marketplace add ljucask/pureinn-product-development▊Pureinn is an AI-native product development framework for Claude Code. It covers the full product lifecycle - from the first idea to a shipped product - through 50 skills and a structured three-playbook engine.
Install
/plugin marketplace add ljucask/pureinn-product-development
/plugin install pureinn-product-development@pureinn-product-development
Select user scope to make it available across all projects.
Quick start
/pureinn "your product idea"
The engine scans your workspace, asks 9 intake questions, selects the right playbook, and presents an ordered skill queue. Run skills one at a time. Run /pureinn again after each phase to check the exit gate and advance.
/pureinn-resume [project-slug] # resume a paused project (omit slug to list all)
/pureinn map # full framework overview - all playbooks, phases, skills
Three playbooks
| Playbook | Use when |
|---|---|
| Greenfield | New product, zero users, validating PMF |
| Feature Implementation | Product exists, active users, adding new functionality |
| Rebuild | Onboarding an existing product into Pureinn (legacy docs or clean) |
Run /pureinn [product idea] and the engine routes you automatically.
Fast tracks
Skip phases you don't need.
Greenfield Express - validated idea, skip discovery:
/pureinn "your idea" # workspace setup
/pm-entity-registry # lean entity list
/pm-business-rules-library # core rules, Draft mode
/pm-features-list # feature inventory + FEAT-IDs
/pm-mvp-scope # MVP scope + Delivery Stripes
/pm-feature-design [ID] # JIT spec per feature → build
Feature Implementation - first run on an existing codebase:
/pureinn [project] # workspace setup
/common-ground # tech context from existing code
/pm-reverse-extract # bootstrap registers + feature inventory from codebase
/pm-feature-design [ID] # JIT spec → build
Stage shortcuts
Jump straight into one part of the framework:
/pureinn define # current project → Commercial Definition
/pureinn acme model # named project → Domain Modeling
/pureinn discover "food delivery app" # fresh project → Discovery
| Keyword | Enters | You exit with |
|---|---|---|
setup | Phase 1 - Foundation | Project skeleton |
discover | Phase 2 - Discovery | Market / personas / JTBD / domain understanding |
validate | Phase 3a - Validation | Go/No-Go verdict |
define | Phase 3b - Commercial Definition | Value prop, business model, KPIs, PRD |
model | Phase 4 - Domain Modeling | Entities, rules, flows blueprint |
plan | Phase 5 - Feature Planning | Feature list, KANO/V×C, MVP scope |
build | Phase 6+7 - JIT Delivery | Per-feature spec + delivery |
For a single artifact, run its skill directly - no stage keyword needed.
Agent mode
Any skill accepts --agent. Instead of running interactively, the skill drafts the artifact autonomously from existing inputs and returns a short summary for your review.
/pm-prd --agent
/pm-market-analysis --agent
Missing inputs are never invented - they're marked [ASSUMED]. No flag = interactive (default). See how it works.
Framework phases
| Phase | What happens | Duration |
|---|---|---|
| Phase 1 - Foundation | Project charter, team, stakeholders | ~1 day |
| Phase 2 - Discovery | Market, tech, domain, customer research | 1-3 weeks |
| Phase 3a - Validation | Hypothesis testing, Go/No-Go verdict | Externally paced |
| Phase 3b - Commercial Definition | Business model, KPIs, PRD | Hours to a few sessions |
| Phase 4 - Domain Modeling | Entities, business rules, process flows | 3-5 days |
| Phase 5 - Feature Planning | Feature list, prioritization, MVP scope | 2-3 days |
| Phase 6+7 - JIT Delivery | Per-feature spec + build cycle | Ongoing |
| Cross-phase skills | Prototype, stress-test, root-cause, audit, meeting, onboarding, diagrams, glossary, stripe | Any time |
| Rebuild | Onboarding an existing product | Varies |
Cross-phase skills at a glance
Skills that run at any point in any playbook - not tied to a phase:
| Skill | When to use |
|---|---|
/pm-prototype | Before any build commitment - compile a tool-ready prompt for Lovable / v0 / Figma Make |
/pm-stress-test | Before exec reviews, investor pitches, board meetings, or any room where you'll be challenged |
/pm-root-cause | When a live metric drops, churn spikes, or a feature isn't being adopted |
/pm-audit | After research injection, re-prioritization, or before a build commitment or pitch |
/pm-meeting | After any meeting - generates structured summary + action items, pushes to Notion |
/pm-onboarding | When a new team member joins - generates a role-specific onboarding brief |
/pm-diagrams | When a visual is needed (user flow, architecture, ERD, JTBD forces) |
/pm-glossary | Start early, update whenever new domain terminology surfaces |
/pm-stripe | Orchestrate and monitor the JIT delivery cycle across all active Delivery Stripes |
