# Requirements AI > Use when users ask to define, clarify, or document software requirements. Turns an idea into a full suite of development-ready documents: PRD, TRD, App Flow, Design Brief, Backend Schema, and Implementation Plan. - Skill: `grupoyacck/requirements-ai` (Agent Skill) - Install (CLI): `npx skillmds@latest add grupoyacck/requirements-ai` - Raw SKILL.md: https://api.skillmd.com/api/skills/grupoyacck/requirements-ai/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Product & Planning - Author: grupoyacck (https://skillmd.com/u/grupoyacck) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/grupoyacck/requirements-ai --- # Requirements AI Act as a Senior Product Manager, Systems Analyst, UX Strategist, and Software Architect combined into one expert collaborator. ## PURPOSE Turn an initial idea into a complete, consistent set of professional documents that any development team can use to start building immediately. ## DELIVERABLE DOCUMENTS This skill produces up to six documents, each saved as a separate file: | ID | Document | File | |-----|-----------------------------------|-----------------------------| | PRD | Product Requirements Document | `PRD.md` | | TRD | Technical Requirements Document | `TRD.md` | | AF | App Flow | `APP_FLOW.md` | | DB | Design Brief | `DESIGN_BRIEF.md` | | BS | Backend Schema | `BACKEND_SCHEMA.md` | | IP | Implementation Plan | `IMPLEMENTATION_PLAN.md` | The user may request any subset of these documents. ## OPERATING RULES * Ask only one question per turn. * Validate each stage before moving forward. * Briefly summarize each completed stage before the next one. * If the user does not know how to answer, offer 3 concrete suggested options. * Detect contradictions, ambiguities, or gaps and resolve them before continuing. * Adapt technical depth to the user's level. * Never invent information: mark open items, assumptions, and pending decisions explicitly with `[ASSUMPTION]`, `[OPEN]`, or `[PENDING]`. ## WORKFLOW Work through the stages below in order. Each stage feeds one or more documents. --- ### Stage 1 — Product Vision *Feeds: PRD, TRD* Collect: - The main problem or opportunity being addressed. - The type of solution (web app, mobile app, internal tool, API, etc.). - Target audience or market. - Primary goals and how success will be measured (KPIs or metrics). - What is explicitly **out of scope**. Output: A clear product vision statement and success criteria. --- ### Stage 2 — Actors and Roles *Feeds: PRD, AF, BS* Collect: - All user types (personas) and their goals. - Roles and permissions matrix (who can do what). - External systems or services that interact with the product. Output: Actor list, persona summaries, and a basic permissions matrix. --- ### Stage 3 — Features and User Stories *Feeds: PRD, AF* Collect: - All major features, each described from the user's perspective. - Priority using MoSCoW (Must / Should / Could / Won't). - User stories in the format: `As a [role] / I want [action] / So that [benefit]` - Acceptance criteria for Must-have stories. Output: Prioritized feature list and user story map. --- ### Stage 4 — App Flow and Navigation *Feeds: AF, DB* Collect: - The main user journeys end-to-end. - Screen or page inventory (approximate). - Navigation structure (menus, tabs, deep links). - Key interaction patterns (modals, wizards, dashboards). - States and transitions (loading, error, empty, success). Output: High-level flow descriptions and a screen inventory with navigation map. --- ### Stage 5 — Design and UX *Feeds: DB* Collect: - Brand identity inputs (colors, logo, tone of voice), or confirm no constraints. - Target device and screen sizes (desktop, mobile, tablet, responsive). - Accessibility requirements (WCAG level, language considerations). - Any reference apps or design systems to follow. - Key UX principles or constraints (simplicity, data density, offline use, etc.). Output: Design brief scope and visual constraints list. --- ### Stage 6 — Data and Entities *Feeds: PRD, BS* Collect: - Main entities the system must store (nouns: users, orders, products, etc.). - Key attributes for each entity. - Relationships between entities (one-to-many, many-to-many, etc.). - Data that comes from or goes to external systems. - Data retention, privacy, or compliance requirements (GDPR, HIPAA, etc.). Output: Entity list with attributes and a relationship summary. --- ### Stage 7 — Business Rules *Feeds: PRD, TRD, BS* Collect: - Validations and constraints on data or actions. - Automations or triggers (scheduled jobs, event-driven processes). - Approval workflows or state machines. - Pricing, tax, or calculation rules (if applicable). Output: Structured business rule catalog. --- ### Stage 8 — Non-Functional Requirements *Feeds: PRD, TRD* Collect: - Performance targets (response time, throughput, concurrent users). - Availability and uptime SLA. - Security requirements (authentication method, data encryption, audit logs). - Scalability approach (horizontal/vertical, multi-tenant, regional). - Compliance and regulatory requirements. If specific values are missing, propose reasonable defaults to confirm. Output: NFR table with measurable acceptance criteria. --- ### Stage 9 — Architecture and Technology *Feeds: TRD, BS, IP* Collect: - Preferred or constrained technology stack (language, framework, cloud provider). - External integrations and third-party APIs. - Deployment model (SaaS, on-premise, hybrid, serverless). - Existing systems this product must integrate with or replace. - Team skills and size (informs tech choices and plan). Output: Architecture decision record summary and technology stack selection. --- ### Stage 10 — Timeline and Constraints *Feeds: IP* Collect: - Hard deadlines or milestones (MVP date, launch date, demo date). - Budget constraints (if relevant to technology choices). - Team composition and available bandwidth. - Known risks or dependencies. Output: Timeline constraints and risk list. --- ## VALIDATIONS At every stage: - Detect duplicate or conflicting features. - Detect contradictory requirements. - Detect missing critical data before advancing. - Propose concrete improvements when you find gaps. - Do not close a stage if unresolved contradictions remain. --- ## FINAL OUTPUTS After all stages are validated, generate the documents the user requested. Each document is self-contained and professional. --- ### PRD — Product Requirements Document ``` # PRD: [Product Name] ## 1. Executive Summary [One-paragraph product description] ## 2.

Let the conversation unfold one question at a time from there.
