Resources

Keep exploring after today's sessions. These are the tools, SDKs, and references referenced throughout the day.

Start building

  • Certification

    GitHub Certifications

    Validate your GitHub skills with official certifications, including GitHub Copilot - a great next step after today.

  • Curated list

    Awesome Copilot

    Community-curated prompts, instructions, chat modes, and skills for getting more out of GitHub Copilot.

  • SDK

    GitHub Copilot SDK

    Embed the Copilot agent runtime in your own apps and services - TypeScript, Python, Go, .NET, Rust and Java.

  • Desktop app

    GitHub Copilot App

    The desktop control centre for parallel agent sessions, built on the Copilot CLI, available on macOS, Windows and Linux.

  • Toolkit

    Spec Kit

    A spec-driven development toolkit that helps you turn ideas into specs and specs into working software with an agent.

  • Platform engineering

    Git-Ape

    An agent-first take on platform engineering for Azure - natural-language intent to IaC, with a blocking security gate, cost estimation, WAF assessment, and drift detection built in, instead of a catalogue of pinned modules.

  • Playbook

    VS Code Engineering Playbook

    Lessons extracted from microsoft/vscode - how one of the world's largest TypeScript codebases achieves fast tests, strict linting, and tight CI feedback.

  • Framework

    HVE Core

    Hypervelocity Engineering prompt library for GitHub Copilot - specialised agents, reusable prompts, coding instructions, and validated skills for a repeatable, standards-aligned workflow.

  • Multi-agent

    About the rubber duck agent

    A built-in critic that reviews Copilot's own plans, code, and tests using a different model - the Advisor pattern from today's keynote, shipped out of the box.

  • Automation

    GitHub Agentic Workflows (gh-aw)

    Define AI-powered repository automation in Markdown with YAML frontmatter, compiled into standard, sandboxed GitHub Actions workflows with scoped, validated writes.

  • CLI

    GitHub Copilot CLI docs

    Install and reference guide for the terminal-native Copilot agent - interactive and scripted usage.

  • Best practices

    Copilot CLI best practices

    Guidance on sandboxing, approvals, and getting reliable results from long-running CLI sessions.

  • Isolation

    Cloud and local sandboxes

    How Copilot CLI runs securely on your machine or in an isolated cloud environment, and how to configure or govern it.

  • Autonomy

    Delegating tasks to Copilot

    Autopilot mode versus /delegate - two ways to hand a task off to Copilot and let it run further ahead on its own.

  • Git workflow

    GitHub Desktop 3.6: worktrees and Copilot integration

    Native git worktree support in GitHub Desktop, plus Copilot-powered commit authoring and merge conflict resolution - the same isolation pattern used by the Copilot CLI and app.

  • Cost & efficiency

    Improving token efficiency in GitHub Agentic Workflows

    How GitHub instrumented, audited, and optimized token usage across its own production agentic workflows - unused tools, deterministic data-gathering, and an Effective Tokens cost metric.

  • Engineering

    Improving token efficiency in GitHub Copilot (VS Code)

    How the VS Code team cut token usage at the harness level with extended prompt caching, smarter cache breakpoints, and tool search - with real experiment numbers for OpenAI and Anthropic models.

  • Tutorial

    Optimizing your AI usage

    Eight practical habits to reduce AI credit spend - model choice, prompt scoping, context hygiene, cache preservation, session limits, and deterministic guardrails.

  • Protocol

    Model Context Protocol (MCP)

    The open protocol behind Copilot's tool integrations - connect your own data sources and tools to any compatible agent.

  • Platform

    Microsoft Foundry

    Model routing, observability, and enterprise management for hosted agent runtimes.

  • Governance

    Copilot policies by surface

    Reference for which enterprise and organisation policies apply to each Copilot surface.

  • Administration

    Enterprise-managed settings

    Configure managed-settings.json to control Copilot client behaviour across your organisation.

  • Community

    GitHub Copilot Community Discussions

    Ask questions, share feedback, and see what other developers are building with Copilot.
