## Overview

Draft and validate Product Requirements Documents for SaaS products: subscription models, multi-tenant, trials, usage-based pricing, onboarding, and retention.

## Example Conversation

> **You:** I need a PRD for our new subscription and trial flow. We're moving to usage-based billing and want to document onboarding and retention.

> **Agent:** I'll use the SaaS PRD skill. I'll clarify scope, load the best-practices and sections checklist, then draft from the template. First: who's the primary audience (SMB, enterprise)? What does "activated" mean for your product?

> **You:** SMB and prosumer. Activated = first successful run of our core workflow.

> **Agent:** I've created `prd-subscription-trial.md` from the template and filled Overview, Goals, User personas, Subscription/usage model, Key features, Onboarding & retention, and Success metrics. Running `validate_prd_structure`...

> **Agent:** **NEEDS_REVISION** — two placeholders remain: [Primary goal] and [North Star / primary]. I've updated those sections with your earlier context. Re-running validation... **PASS**. The PRD has all required sections and no placeholders.

## What the Tools Validate

**`validate_prd_structure`** checks the PRD document for:

- **Required sections** — Overview, Goals, User personas, Subscription/usage model, Key features, Success metrics, Non-functional requirements. Missing sections are reported as errors.
- **Placeholders** — Flags `[TODO]`, `[TBD]`, `[Insert]`, or bracketed placeholders (e.g. `[Product name]`) so you can replace them before finalising.

**Output:** PASS when there are no errors and no unfilled placeholders; NEEDS_REVISION when only warnings (e.g. placeholders); FAIL when required sections are missing. Fix flagged items and re-run until the check passes.

## Output Excerpt
