Build Copilot Extensions faster with skillsets

Skillset header image

Today we’re introducing skillsets, a new lightweight way to build GitHub App-based Copilot Extensions alongside our existing agents approach. While agents offer full control over the user interaction, skillsets make it easy to integrate external tools and services into Copilot Chat by defining simple API endpoints – no AI expertise needed!

What’s new ✨

  • Let Copilot handle all AI interactions and response formatting
  • Define up to 5 skill endpoints that Copilot can call
  • Simple JSON schema configuration
  • Quick setup with minimal code

Benefits for builders ⚡️

  • Faster Development: Focus on your core functionality instead of AI interactions
  • Simple Implementation: Just define API endpoints, without managing LLM logic
  • Minimal Setup: No complex server infrastructure required, with the option to use existing APIs
  • Consistent Experience: Copilot maintains natural chat interactions automatically

Choosing your integration path 🛠

  1. Skillsets: Perfect for straightforward integrations like data retrieval and basic actions. You provide the API endpoints, and Copilot handles workloads like prompt crafting and response generation.
  2. Agents: Ideal for complex workflows needing custom logic, flexible prompt crafting, or specific LLM models. You control the entire interaction.

How it works 🏗️

End users interact with skillset-based extensions just like any other Copilot Extension. Just type @ followed by the extension name and ask in natural language. Behind the scenes, Copilot:

  • Analyzes the query to determine which skill to call
  • Structures the API request based on your JSON schema
  • Calls your endpoint to get the data
  • Formats and generates the response in chat

Architecture

Requirements for extension builders

  • Access to GitHub Copilot
  • For organizational builds: Free, Team, or supported Enterprise Cloud organization types
  • Skillsets only apply to extensions built as GitHub Apps, and not VS Code chat participants

Getting started 🚀

Check out our documentation to learn how to build your first skillset.

Already built a Copilot Extension as an agent? Existing agent extensions can be converted into skillsets, but one extension cannot be both a skillset and an agent.

Copilot content exclusion is now generally available in IDEs

We’re excited to announce that content exclusion for Copilot is now generally available for all Copilot Business and Copilot Enterprise users! This feature, previously available only in beta, allows you to control which code Copilot can access to generate suggestions. When you exclude content from Copilot:

  • Code completion will not be available in the affected files.
  • The content in affected files will not inform code completion suggestions in other files.
  • The content in affected files will not inform GitHub Copilot Chat’s responses.

How to exclude content using content exclusions for Copilot?

Enterprise, organization, and repository admins can set up exclusions through their settings, as outlined in our documentation: Excluding content from GitHub Copilot

For availability across surfaces, please check the information here: Availability of content exclusion

Enterprise admin Copilot Content Exclusions

For users previously in beta:

Previously Used Enterprise-Level Rules:

  • If you already had enterprise-level exclusion rules set up (as described in previous changelog), you won’t experience any changes. These rules will continue to function as intended.

Previously Used Organization-Level Rules:

  • If your exclusions were previously set at the organization level but not the enterprise level: Org-level rules will no longer apply enterprise-wide. They will be limited to users who are assigned Copilot seats from your org, regardless of whether enterprise-level rules are applied.

Copilot subscription-based network routing is now enforced

Network requests for Copilot are routed based on a user’s Copilot subscription. Requests for Copilot Individual, Copilot Business, and Copilot Enterprise users now route through different endpoints.

This change enables Copilot Business and Copilot Enterprise customers to make sure all Copilot users on their networks are accessing Copilot through their Copilot Business or Copilot Enterprise subscription, and that all Copilot user data is handled according to the terms of their Copilot Business or Copilot Enterprise agreement. In essence, customers will be able to use their network firewall to explicitly allow access to Copilot Business or Copilot Enterprise, and/or block access to Copilot Individual.

Today we enabled enforcement of the user’s subscription on the new endpoints, ensuring only Copilot Business users can connect to Copilot Business endpoints and only Copilot Enterprise users can connect to Copilot Enterprise endpoints.

Copilot Autofix for Dependabot now available for TypeScript repositories (private preview)

Copilot Autofix for Dependabot is now available in private preview for TypeScript repositories.

This new feature combines the power of GitHub Copilot with Dependabot, making it easier than ever to automatically fix breaking changes introduced by dependency updates. With Copilot Autofix, you can save time and minimize disruptions by receiving AI-generated fixes to resolve breaking changes caused by dependency upgrades in Dependabot-authored pull requests.

Why Copilot Autofix for Dependabot?

Dependency updates can introduce breaking changes that lead to failing CI tests and deployment delays.

Security campaigns with Copilot Autofix are now in public preview

Security campaigns with Copilot Autofix are now in public preview. Available as part of GitHub Advanced Security, security campaigns rapidly reduce your backlog of application security debt. By using Copilot Autofix to generate contextual explanations and code suggestions for up to 1,000 historical code scanning alerts at a time, security campaigns help developers and security teams collaborate to fix vulnerabilities with speed and confidence.

Code scanning detection engines such as GitHub’s CodeQL are incredibly effective at automatically notifying developers about potential security vulnerabilities in their code in the form of code scanning alerts. Most developers fix these vulnerabilities with the help of Copilot Autofix when they’re flagged pull requests. However, in situations where these alerts aren’t remediated in a timely manner, security debt can build up and pose a serious risk to deployed applications. Using security campaigns, security teams and developers can easily collaborate to remediate and eradicate security debt at scale, with the help of Copilot Autofix.

A security campaign on GitHub can contain a large number of code scanning alerts, prioritized by your security team to be fixed within a chosen timeframe. When a campaign is created, Copilot Autofix automatically suggests fixes for all supported alerts, and developers who are most familiar with the code are notified. From there, they can review the fixes, open pull requests, and remediate the security debt.

Security teams can monitor the progress of the campaign and track the number of alerts that have been fixed. Using security campaigns, security and developer teams work together with Copilot Autofix to remove security debt in targeted efforts aimed at maximizing impact by focusing on the alerts that matter.

Security campaigns are available for users of GitHub Advanced Security on GitHub Enterprise Cloud. For more information about security campaigns, see About security campaigns in the GitHub documentation.
