Prepare designs for development handoff. Document specifications, interactions, and assets to enable efficient development and maintain design quality.
This skill should be used when the user asks to "create a PRD for Replit", "write product requirements", "document app specifications", "prepare a product spec", or needs a comprehensive specification document that Replit Agent can use for complex, multi-feature applications. Creates structured PRDs optimized for AI-powered development.
Archives completed changes and merges specification deltas into living documentation. Use when changes are deployed, ready to archive, or specs need updating after implementation. Triggers include "openspec archive", "archive change", "merge specs", "complete proposal", "update documentation", "finalize spec", "mark as done".
Design new APIs or review existing ones using debate-driven multi-agent workshop. Agents propose designs and challenge each other on consumer UX, domain modeling, security, performance, and standards compliance.

Triggers: "design product", "new product idea", "product concept", "product development", "product spec", "iterate on product", "product design", "invention", "prototype spec", "product requirements", "product engineering", "develop product" Outputs: Product specification, BOM estimate, feature breakdown, differentiation analysis.
Audit specification quality and generate compliance report.
Transform specifications into actionable implementation plans with phases, tasks, and acceptance criteria. Use when: (1) User asks to create/write an implementation plan, (2) User asks to plan implementation from a specification, (3) Converting specifications from .workflows/specification/{topic}/specification.md into implementation plans, (4) User says 'plan this' or 'create a plan', (5) Need to structure how to build something with phases and concrete steps. Creates plans in .workflows/planning/{topic}/plan.md that can be executed via strict TDD.
Product Requirements Document creation and feature specification writing. Use when writing PRDs, technical specs, feature documentation, or requirements. Triggers on "PRD", "product requirements", "feature spec", "technical requirements", "functional spec".
Conversational SDD (Specification-Driven Development) guidance skill based on OpenSpec. It is automatically triggered when a user describes development requirements, and guides the user through the entire SDD process via conversations without any manual command input.
