Decision brief
What it does—and where it fits
Prompt for creating the high-level technical architecture for an Epic, based on a Product Requirements Document.
Not for
- Tasks that require unconfirmed production actions or broad system permissions.
- Environments where the pinned source and install steps cannot be inspected.

Installation
Inspect first. Install second.
The source command is displayed only when detected. A safe inspection prompt is always available so your agent can explain every action before execution.

Static risk signals and limitations
No configured static risk pattern was detected
This is not proof of safety. Runtime behavior, indirect dependencies, and hidden external systems are outside the static scan.

Epic Architecture Specification Prompt
Goal
Act as a Senior Software Architect. Your task is to take an Epic PRD and create a high-level technical architecture specification. This document will guide the development of the epic, outlining the major components, features, and technical enablers required.
Context Considerations
- The Epic PRD from the Product Manager.
- Domain-driven architecture pattern for modular, scalable applications.
- Self-hosted and SaaS deployment requirements.
- Docker containerization for all services.
- TypeScript/Next.js stack with App Router.
- Turborepo monorepo patterns.
- tRPC for type-safe APIs.
- Stack Auth for authentication.
Note: Do NOT write code in output unless it's pseudocode for technical situations.
Output Format
The output should be a complete Epic Architecture Specification in Markdown format, saved to /docs/ways-of-work/plan/{epic-name}/arch.md.
Specification Structure
1. Epic Architecture Overview
- A brief summary of the technical approach for the epic.
2. System Architecture Diagram
Create a comprehensive Mermaid diagram that illustrates the complete system architecture for this epic. The diagram should include:
- User Layer: Show how different user types (web browsers, mobile apps, admin interfaces) interact with the system
- Application Layer: Depict load balancers, application instances, and authentication services (Stack Auth)
- Service Layer: Include tRPC APIs, background services, workflow engines (n8n), and any epic-specific services
- Data Layer: Show databases (PostgreSQL), vector databases (Qdrant), caching layers (Redis), and external API integrations
- Infrastructure Layer: Represent Docker containerization and deployment architecture
Use clear subgraphs to organize these layers, apply consistent color coding for different component types, and show the data flow between components. Include both synchronous request paths and asynchronous processing flows where relevant to the epic.
3. High-Level Features & Technical Enablers
- A list of the high-level features to be built.
- A list of technical enablers (e.g., new services, libraries, infrastructure) required to support the features.
4. Technology Stack
- A list of the key technologies, frameworks, and libraries to be used.
5. Technical Value
- Estimate the technical value (e.g., High, Medium, Low) with a brief justification.
6. T-Shirt Size Estimate
- Provide a high-level t-shirt size estimate for the epic (e.g., S, M, L, XL).
