Engineering-Ready PRD
Write or harden a PRD until it passes a 12-point engineering readiness gate, so engineers can estimate it without follow-up questions.
Before & after
Same prompt, same agent — the only difference is the skill.
A PRD is a good way to align the team on what you're building. It usually covers the problem, goals, and how you'll solve it. There are different formats, so you might want to decide on structure first. What feature are you scoping?
PRODUCT REQUIREMENTS DOCUMENT: PROBLEM STATEMENT: Creators lose 2+ hours per week manually scheduling posts across 3+ platforms. Workaround = spreadsheets + calendar apps + manual copy-paste. Goal: 30-second drag-and-drop scheduling. SUCCESS METRICS: • Adoption: 30% of users schedule 1+ post within 2 weeks • Time saved: Average 1.5h/week per active user (self-reported) • Retention: 80% monthly active users re-schedule within 7 days OUT OF SCOPE (Phase 1): ✗ Analytics integration (Phase 2) ✗ AI caption generation (toolmaker partnership later) ✗ Rights management (photo credits) REQUIREMENTS: 1. Drag-and-drop calendar → pick date/time 2. Multi-platform publish (YouTube, Instagram, TikTok in beta) 3. Publish queue visible (show 30-day forecast) 4. Preview before confirm (actual rendering per platform) 5. Rollback: unpublish within 30s if mistake DEPENDENCIES: • Platform APIs updated (2-week lead time) • Analytics dashboard ready (blocks full Phase 2) RISKS: ⚠ Platform rate-limits on bulk publishes (mitigation: stagger 5s apart) ⚠ Time zone confusion (mitigation: show creator's local + UTC) TIMELINE: Design sprint 1 week, build 4 weeks, beta 2 weeks.
About this skill
Write the PRD that answers engineering's questions before they ask them. It covers scope and non-goals, testable acceptance criteria, edge cases, permissions, and non-functional requirements, and it gets checked against a readiness gate.
What it does
- Sets explicit scope, at least three non-goals, and assumptions for engineering to challenge
- Writes functional requirements with priorities and Given/When/Then acceptance criteria
- Specifies edge cases and error states, data fields, a role matrix, performance targets, analytics events, and rollout
- Grades an existing draft against 12 readiness questions and turns failures into owned open questions
What you get
A 12-section PRD with a readiness score and a list of open questions, each with an owner, a due date, and whether it blocks estimation.
Best for
Product managers and founders handing an approved feature to engineering for estimation.

name: engineering-ready-prd
description: Write or harden a product requirements document until it passes an engineering readiness gate - explicit scope and non-goals, testable acceptance criteria, edge cases, data and permission rules, non-functional requirements, and a list of open questions with owners - so engineers can estimate and build without repeated round-trips. Use when the user asks to write a PRD, spec a feature for engineering, or check whether an existing PRD is ready for sprint planning, including casual asks like "turn this brief into a spec", "is this PRD good enough for eng", or "what's missing from this spec".
