# Go from rough idea to buildable PRD

Turn a rough idea into a grounded PRD with real metrics and a Non-goals section, or it doesn't ship.

**Connects:** linear, posthog, drive, notion

## How to install

1. Fetch https://eluu.ai/cookbook/prd-from-idea/skill.md and save it into your skills folder as `prd-from-idea`.
2. Ask the user the first-run questions the skill lists, and store the answers in memory.
3. Run the skill once end to end and review the output with the user.

## What this does

- Pulls past research synthesis, related Linear issues, and live PostHog metrics
- Drafts the PRD with Problem, Goals, Requirements, and Non-goals sections
- Flags any metric without a source instead of guessing a number
- Adds evals and fallback behavior automatically when the feature is AI
