Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by github on GitHub. Read the source before you install it.

Installation

Install the Breakdown Epic Arch AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/github/awesome-copilot.git /tmp/awesome-copilot
mkdir -p .claude/skills
cp -r /tmp/awesome-copilot/skills/breakdown-epic-arch .claude/skills/breakdown-epic-arch

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Breakdown Epic Arch in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Breakdown Epic Arch on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Breakdown Epic Arch is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

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).

Frequently asked questions

What does the Breakdown Epic Arch AI skill do?

Prompt for creating the high-level technical architecture for an Epic, based on a Product Requirements Document.

Why use Breakdown Epic Arch on TypingMind?

Because you install it once and use it with any model. Breakdown Epic Arch is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Breakdown Epic Arch in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/github/awesome-copilot/tree/main/skills/breakdown-epic-arch. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Breakdown Epic Arch?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Breakdown Epic Arch?

As many as you like. As long as a model supports skills, you can use Breakdown Epic Arch with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Breakdown Epic Arch AI skill free?

Yes. It is published on GitHub by github under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
