Learning Objectives by Module

Welcome & Foundations (15 min)

• Understand what GitHub Copilot is and how it fits into the enterprise software development lifecycle
• Identify the different Copilot plans (Business vs Enterprise) and their capabilities
• Understand Copilot's privacy, security, and IP indemnity guarantees for enterprise use

Module 1: Copilot in VS Code - Core Experience (45 min)

• Receive and accept inline code suggestions using Tab, partial accept, and next edit suggestions
• Write effective comment-driven prompts that produce accurate code completions
• Navigate alternative suggestions and understand when to accept, modify, or reject them
• Apply Copilot code suggestions to real enterprise tasks: CRUD operations, data transformations, and boilerplate reduction

Module 2: Copilot Chat - Deep Dive (60 min)

• Use Chat participants (@workspace, @terminal, @github), slash commands, and chat variables to craft precise prompts
• Distinguish between Ask, Edit, Agent, and Plan modes and select the right one for a given task
• Generate, explain, and fix code using Copilot Chat with enterprise-grade examples
• Write unit tests for existing code using Copilot Chat in both Java and JavaScript

Module 3: Copilot on GitHub.com - GHEC (45 min)

• Use Copilot Chat on GitHub.com to query repositories, explain code, and explore codebases
• Generate pull request summaries with Copilot
• Use Copilot code review to get AI-powered review feedback on pull requests
• Leverage Copilot from the search bar and dashboard for repository-scoped questions

Module 4: Customization - Instructions & Prompt Files (60 min)

• Create repository-wide custom instructions (.github/copilot-instructions.md) to enforce coding standards
• Build path-specific instruction files (.instructions.md) with applyTo frontmatter for language/framework-specific rules
• Author reusable prompt files (.prompt.md) as slash commands for common enterprise workflows
• Understand the instruction priority hierarchy: personal > repository > organization

Module 5: Agent Mode & Custom Agents (75 min)

• Use Agent mode in VS Code for autonomous multi-step tasks with terminal command execution
• Create custom agents (.agent.md) with specialized tools, instructions, and model selection
• Implement handoffs between agents for sequential multi-step workflows (e.g., Plan → Implement → Review)
• Understand and configure subagents for parallel task delegation and context isolation
• Build an orchestration pattern using coordinator and worker agents with the agents property

Wrap-up, Q&A & Next Steps (30 min)

• Review key takeaways and identify areas for immediate adoption
• Understand enterprise governance: policy management, audit logs, content exclusions, and usage metrics
• Create an action plan for rolling out Copilot customizations to your team
