It aligns engineering, design, QA, and stakeholders around a shared understanding. This skill helps you write PRDs that are clear, complete, and actionable — with enough context for good decisions and enough specificity for reliable execution. ## When to Use - You've validated a problem and solution through discovery - You need to hand off a feature to engineering and design - Multiple teams need to coordinate on a shared initiative - You want to document decisions and context for future reference - Don't use for: speculative ideas (PRD is for committed work), tiny changes (use a ticket), or trying to think through a problem (use a brief or spec doc first) ## Instructions ### 1. Start with the Why **Problem Statement**: What problem are we solving? (Reference the problem-statement skill) **Evidence**: Link to customer interviews, analytics, experiments **Strategic Context**: How does this align with OKRs or product strategy? ### 2. Define Scope **In scope**: What's included? Be specific. **Out of scope**: What's explicitly NOT included? (Prevents scope creep) **User stories**: Brief list of what users can do after this ships ### 3. Detail the Requirements For each feature or change: - **Description**: What it does and why it exists - **User experience**: How users interact with it - **Acceptance criteria**: Given/When/Then format (see acceptance-criteria skill) - **Edge cases**: Empty states, error states, permission states - **Analytics**: What events to track ### 4. Define Success **North star**: What outcome does this serve? **Success metrics**: How will we know it's working? (see metrics-framework) **Counter-metrics**: What should NOT degrade? **Launch criteria**: What must be true before we ship? **Time to evaluation**: When after launch will we measure success? ### 5. Add Logistics **Dependencies**: What other work or teams does this depend on? **Timeline**: When does each phase ship? **Risks**: What could go wrong and what's the mitigation? **Open questions**: What decisions are still pending? ## PRD Template ```markdown # PRD: [Feature Name] ## Status: [Draft / Reviewing / Final / Shipped] ## Problem Statement [Link to problem statement + evidence] ## Strategic Context - OKR: [link] - Strategy: [how this fits] - Target users: [who] ## Scope **In scope**: [bullet list] **Out of scope**: [bullet list] ## Requirements ### [Feature 1] Description: ... Acceptance criteria: - Given..., When..., Then... Edge cases: ... Analytics: ... ### [Feature 2] ... ## Success Metrics - Primary: [metric + target] - Counter-metric: [what not to break] - Launch criteria: [what must be true to ship] ## Logistics - Dependencies: [teams, features, timelines] - Risks: [what could go wrong] - Timeline: [phases and dates] - Open questions: [decisions needed] ``` ## Sample Output (Excerpt) **Problem**: Users take 4+ hours/week in status meetings **Solution**: Async team updates with AI summaries **Success metric**: Reduce meeting hours by 50% within 30 days of launch **Launch criteria**: 95% uptime, < 2s response time, all-edge cases handled **Out of scope**: Mobile app, SSO integration, custom templates ## Common Pitfalls 1. **PRD as a wishlist** — Every feature doesn't belong in every release. Be ruthless 2. **Skipping the "why"** — Without context, engineers will make bad decisions about *how* 3. **Premature detail** — Don't specify implementation details you haven't thought through 4. **No success criteria** — If you don't define "good," you'll never know if you shipped "good" 5. **Living doc that never ships** — PRDs should drive execution, not become archive documents ## Verification Checklist - [ ] Problem statement included with evidence - [ ] Requirements have clear acceptance criteria - [ ] Edge cases documented (empty, error, permission states) - [ ] Success metrics defined with targets - [ ] Launch criteria documented - [ ] Open questions tracked with owners ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [uthumany](https://github.com/uthumany) - **Source:** [uthumany/uthy-legacy-os](https://github.com/uthumany/uthy-legacy-os) - **License:** MIT - **Homepage:** https://uthumany.github.io/uthy-legacy-os/ Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-uthumany-uthy-legacy-os-prd-writer - Seller: https://agentstack.voostack.com/s/uthumany - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
