HVE Core - Coding Standards

Language-specific coding instructions and pre-PR code review agents for bash, Bicep, C#, PowerShell, Python, Rust, and Terraform projects

Enforce language-specific coding conventions and best practices across your projects, with pre-PR code review agents for catching functional defects early. This collection provides instructions for bash, Bicep, C#, PowerShell, Python, Rust, and Terraform that are automatically applied based on file patterns, plus agents that review branch diffs before opening pull requests.

This collection includes:

Code Review Functional — Pre-PR branch diff reviewer for functional correctness, error handling, edge cases, and testing gaps
Code Review Standards — Skills-based code reviewer that enforces project-defined coding standards via dynamic skill loading
Code Review Full — Orchestrates both functional and standards reviews in a single pass

Instructions for:

Bash — Shell scripting conventions and best practices
Bicep — Infrastructure as code implementation standards
C# — Code and test conventions including nullable reference types, async patterns, and xUnit testing
PowerShell — Script and module conventions including comment-based help, CmdletBinding, PSScriptAnalyzer compliance, and copyright headers
Python — Scripting implementation with type hints, docstrings, uv project management, and pytest testing
Rust — Rust development conventions targeting the 2021 edition
Terraform — Infrastructure as code with provider configuration and module structure

Getting Started

After installing this extension, the chat agents are available in GitHub Copilot Chat:

Use custom agents by selecting the custom agent from the agent picker drop-down list in Copilot Chat
Apply prompts through the Copilot Chat interface
Reference instructions: they are automatically applied based on file patterns

Post-Installation Setup

Some chat agents create workflow artifacts in your project directory. See the installation guide for recommended .gitignore configuration and other setup details.

Pre-release Channel

HVE Core offers two installation channels:

Channel	Description	Maturity Levels
Stable	Production-ready artifacts only	`stable`
Pre-release	Early access to new features and experimental artifacts	`stable`, `preview`, `experimental`

To install the pre-release version, select Install Pre-Release Version from the extension page in VS Code.
