Hypervelocity Engineering (HVE) Core

HVE Core helps teams ship faster with GitHub Copilot by combining specialized agents, reusable prompts, coding instructions, and validated skills into one workflow system.

Use HVE Core when you want AI-assisted work to be repeatable, standards-aligned, and scalable across individuals and teams. HVE Core provides structured AI workflow building blocks:

• Agents for specialized tasks such as research, planning, implementation, and review
• Prompts for repeatable workflow entry points
• Instructions that apply coding standards automatically
• Skills that add reusable tool capabilities

[!CAUTION] HVE Core is a highly opinionated, rapidly evolving agentic SDLC framework. It is best treated as a source of patterns and learning rather than a stable platform, foundation, or production dependency. Workflows, interfaces, architecture, and recommended practices may change substantially, including in ways that are not backward compatible, as the technology landscape evolves. Evaluate all materials for your own requirements and risk tolerance. The HVE Builder skill (use with /hve-builder) and GitHub Copilot can help you adapt or copy relevant patterns into an agentic SDLC that you own and maintain independently. To build an independent implementation, start with Forking and Extending HVE Core and review the HVE Core documentation before adopting any component.

Where to Start

1. Install the HVE Core extension from the VS Code Marketplace.
2. Open any project and launch GitHub Copilot Chat (Ctrl+Alt+I).
3. Select RPI Agent from the agent picker or run /rpi, then describe the task you want to complete.

[!TIP] Using GitHub Copilot CLI? Choose a marketplace source:

• Ref-less current main: microsoft/hve-core
• Moving reviewed channels: microsoft/hve-core#release/prerelease and microsoft/hve-core#release/stable
• Immutable exact releases: microsoft/hve-core#prerelease-v<version> and microsoft/hve-core#v<version>

For example, register the development tip and install the HVE Core plugin:

copilot plugin marketplace add microsoft/hve-core
copilot plugin install hve-core@hve-core

Reviewed source moves from main to release/prerelease to release/stable. Behavior when switching or duplicating same-name marketplace registrations has not been observed. See CLI Plugins for details.
