Agent-native product management toolkit using first-principles thinking
npx claudepluginhub petrus-han/first-principles-skillsAgent-native product management toolkit. Orchestrates parallel analysis, MVP scoping, and execution planning using first-principles thinking.
Agent-native product management toolkit for Claude Code. Takes a raw product idea and delivers a scoped MVP, PRD, and execution plan — all grounded in first-principles thinking.

The plugin exposes a single skill: first-principles:product-workflow.
It triggers when you say things like:
Or invoke it directly:
/first-principles:product-workflow
Build a webhook integration that syncs Mercury Bank transactions to QuickBooks
The skill runs a 4-phase pipeline with parallel subagents:
| Phase | What happens | Method |
|---|---|---|
| 0. Parse | Extract idea, context, requirements | Orchestrator |
| 1. Analyze | Challenge every requirement + assess constraints | 2 parallel subagents |
| 2. Scope | Merge signals into MVP scope (3-5 items max) | Orchestrator, then user confirms |
| 3. Specify | Write PRD + plan execution tasks | 2 parallel subagents |
| 4. Deliver | Consolidated output | Orchestrator |
