Contributing to Awesome GitHub Copilot

Thank you for your interest in contributing to the Awesome GitHub Copilot repository! We welcome contributions from the community to help expand our collection of custom instructions and skills.

How to Contribute

Adding Instructions

Instructions help customize GitHub Copilot's behavior for specific technologies, coding practices, or domains.

1. Create your instruction file: Add a new .md file in the instructions/ directory
2. Follow the naming convention: Use descriptive, lowercase filenames with hyphens (e.g., python-django.instructions.md)
3. Structure your content: Start with a clear heading and organize your instructions logically
4. Test your instructions: Make sure your instructions work well with GitHub Copilot

Example instruction format

---
description: 'Instructions for customizing GitHub Copilot behavior for specific technologies and practices'
---

# Your Technology/Framework Name

## Instructions

- Provide clear, specific guidance for GitHub Copilot
- Include best practices and conventions
- Use bullet points for easy reading

## Additional Guidelines

- Any additional context or examples

Adding an Agent

Agents are specialized configurations that transform GitHub Copilot Chat into domain-specific assistants or personas for particular development scenarios.

1. Create your agent file: Add a new .agent.md file in the agents/ directory
2. Follow the naming convention: Use descriptive, lowercase filenames with hyphens and the .agent.md extension (e.g., react-performance-expert.agent.md)
3. Include frontmatter: Add metadata at the top of your file with required fields
4. Define the persona: Create a clear identity and expertise area for the agent
5. Test your agent: Ensure the agent provides helpful, accurate responses in its domain

Example agent format

---
description: 'Brief description of the agent and its purpose'
model: 'gpt-5'
tools: ['codebase', 'terminalCommand']
name: 'My Agent Name'
---

You are an expert [domain/role] with deep knowledge in [specific areas].

## Your Expertise

- [Specific skill 1]
- [Specific skill 2]
- [Specific skill 3]

## Your Approach

- [How you help users]
- [Your communication style]
- [What you prioritize]

## Guidelines

- [Specific instructions for responses]
- [Constraints or limitations]
- [Best practices to follow]

Adding Skills

Skills are self-contained folders in the skills/ directory that include a SKILL.md file (with front matter) and optional bundled assets.

1. Create a new skill folder: Run npm run skill:create -- --name <skill-name> --description "<skill description>"
2. Edit SKILL.md: Ensure the name matches the folder name (lowercase with hyphens) and the description is clear and non-empty
3. Add optional assets: Keep bundled assets reasonably sized (under 5MB each) and reference them from SKILL.md
4. Validate and update docs: Run npm run skill:validate and then npm run build to update the generated README tables

Adding Plugins

Plugins group related agents, commands, and skills around specific themes or workflows, making it easy for users to install comprehensive toolkits via GitHub Copilot CLI.

1. Create your plugin: Run npm run plugin:create to scaffold a new plugin
2. Follow the naming convention: Use descriptive, lowercase folder names with hyphens (e.g., python-web-development)
3. Define your content: List agents, commands, and skills in plugin.json using the Claude Code spec fields
4. Test your plugin: Run npm run plugin:validate to verify your plugin structure

Creating a plugin

npm run plugin:create -- --name my-plugin-id

Plugin structure

plugins/my-plugin-id/
├── .github/plugin/plugin.json  # Plugin metadata (Claude Code spec format)
└── README.md                   # Plugin documentation

Note: Plugin content is defined declaratively in plugin.json using Claude Code spec fields (agents, commands, skills). Source files live in top-level directories and are materialized into plugins by CI.

plugin.json example

{
  "name": "my-plugin-id",
  "description": "Plugin description",
  "version": "1.0.0",
  "keywords": [],
  "author": { "name": "Awesome Copilot Community" },
  "repository": "https://github.com/github/awesome-copilot",
  "license": "MIT",
  "agents": ["./agents/my-agent.md"],
  "commands": ["./commands/my-command.md"],
  "skills": ["./skills/my-skill/"]
}

Plugin Guidelines

• Declarative content: Plugin content is specified via agents, commands, and skills arrays in plugin.json — source files live in top-level directories and are materialized into plugins by CI
• Valid references: All paths referenced in plugin.json must point to existing source files in the repository
• Instructions excluded: Instructions are standalone resources and are not part of plugins
• Clear purpose: The plugin should solve a specific problem or workflow
• Validate before submitting: Run npm run plugin:validate to ensure your plugin is valid

Submitting Your Contribution

1. Fork this repository
2. Create a new branch for your contribution
3. Add your instruction, skill, agent, or plugin following the guidelines above
4. Run the update script: npm start to update the README with your new file (make sure you run npm install first if you haven't already)
   • A GitHub Actions workflow will verify that this step was performed correctly
   • If the README.md would be modified by running the script, the PR check will fail with a comment showing the required changes
5. Submit a pull request targeting the staged branch with:
   • A clear title describing your contribution
   • A brief description of what your instruction/skill/agent does
   • Any relevant context or usage notes

Important

All pull requests should target the staged branch, not main.
