GitHub Copilot Demo

This repository is a guided workshop for demonstrating GitHub Copilot across repository context, skills, MCP, custom agents, Copilot CLI, governance, workflow automation, and operations.

The detailed lecture has moved from one giant README into chapter files under docs/workshop. This root README is now the landing page and navigation hub.

Whole story at a glance

The workshop follows one connected engineering story:

• Shape Copilot behavior with repository context — how Copilot is guided by repository instructions, product intent, specifications, and shared planning context.
• Skills and MCP — how Copilot gains capabilities through packaged local skills and connected tools.
• Plan and specialize work in VS Code — prompt files, custom agents, handoffs, and subagents working together.
• Continue execution in Copilot CLI — plan mode, execution, review, research, session history, and execution surfaces.
• Save tokens with context hygiene — scoped context, progressive reveal, compression, and OpenTelemetry-backed measurement.
• Govern delivery with review, security, and hooks — code generation is not the end; add cross-model review with the Critic agent.
• Add workflow agents in GitHub Actions — repository automation after merge.
• Operate with SRE agents — closing the loop with operational thinking and OpenTelemetry observability.

Workshop chapters

Token-efficiency benchmark highlight

The course now includes a measured token-efficiency lab. The headline lecture table is in Chapter 05, with detailed results in tools/copilot-token-lab/suite-example-analysis.md and rerun instructions in tools/copilot-token-lab/README.md. Use the companion article Token saving in GitHub Copilot for the longer narrative and keep the repo chapter focused on measured workshop evidence.

Supporting material

• AGENTS.md defines repository-wide Copilot instructions.
• PRD.md and specs/ provide product and architecture context.
• docs/enterprise_demo_flow.md is the concise presenter flow.
• .github/prompts and .github/skills contain reusable Copilot starts and local capabilities.
• tools/copilot-token-lab contains the token measurement side project.
• Agent skills and central management complements the local skills chapter with central operating-model guidance.

This repository is for demonstrations and learning, not for production use.
