 # Docs changelog
 
+**23 April 2026**
+
+We added documentation for the new `gh skill` command (public preview), which you can use to discover, install, update, and publish agent skills directly from GitHub CLI.
+
+See [Adding agent skills for GitHub Copilot](https://docs.github.com/en/copilot/how-tos/use-copilot-agents/cloud-agent/add-skills#managing-skills-with-github-cli).

+
+We reorganized the Copilot how-tos for GitHub.com into a new [Copilot on GitHub](https://docs.github.com/en/copilot/how-tos/copilot-on-github) category, structured around five task-based map topics that follow the way people actually use Copilot on GitHub:
+
+* [Set up Copilot](https://docs.github.com/en/copilot/how-tos/copilot-on-github/set-up-copilot): Enable Copilot, configure AI models, and set up code review.
+* [Chat with Copilot](https://docs.github.com/en/copilot/how-tos/copilot-on-github/chat-with-copilot): A streamlined [quickstart](https://docs.github.com/en/copilot/how-tos/copilot-on-github/chat-with-copilot/get-started-with-chat) with example prompts, plus focused articles for chat on GitHub and chat on GitHub Mobile.
+* [Customize Copilot](https://docs.github.com/en/copilot/how-tos/copilot-on-github/customize-copilot): Add custom instructions, customize coding agents (MCP, hooks, skills, firewall), and curate context with Spaces and content exclusions. A new [quickstart](https://docs.github.com/en/copilot/how-tos/copilot-on-github/customize-copilot/customize-copilot-overview) walks through a scenario that ties these features together.
+* [Copilot for GitHub tasks](https://docs.github.com/en/copilot/how-tos/copilot-on-github/copilot-for-github-tasks): Create issues, generate PR summaries, and use the GitHub MCP server from the web UI.
+* [Use Copilot agents](https://docs.github.com/en/copilot/how-tos/copilot-on-github/use-copilot-agents) — Six articles following the agent workflow end-to-end: kick off a task, research and iterate, monitor sessions, request code review, and review output. Includes a new [hands-on quickstart](https://docs.github.com/en/copilot/how-tos/copilot-on-github/use-copilot-agents/overview) you can complete in about ten minutes.
+
+Every article was revised for plain language, scannable structure, and value-focused intros. Web-specific content was separated from IDE and CLI content so you see only what's relevant to GitHub.com.

-## Immutable subject claims
-
-The OpenID Connect (OIDC) specification requires subject (`sub`) claims to be locally unique and never reassigned. Previously, the default `sub` format used only organization and repository names. If a namespace was recycled, a different owner could create the same subject value.
-
-To help prevent this scenario, repositories created after June 18, 2026 now use an immutable default subject format that includes both the owner ID and repository ID. This rollout does not include {% data variables.product.prodname_ghe_server %}.

-* Syntax: `repo:OWNER-ID/REPO-ID:ref:refs/heads/BRANCH`
-* Previous format example: `repo:octo-org/octo-repo:ref:refs/heads/main`
-* Immutable format example: `repo:octo-org-123456/octo-repo-456789:ref:refs/heads/main`

-The `-` separator is used between names and IDs because `-` cannot appear in {% data variables.product.github %} usernames or repository names.

-Repositories created before June 18, 2026 keep the previous format unless you opt in to immutable subject claims. You can opt in at the organization or repository level by using the OIDC settings UI or REST API.
