Changelog Mentions "/extensions" but copilot is unaware of this and it does nothing

### Describe the bug

Conversation below:

❯ Your changelog says there should be an extensions shortcut but there doesnt seem to be?

● Checking my documentation
└ # GitHub Copilot CLI Documentation

● Looking at the current help docs, I can see the relevant shortcut is /agent — not an "extensions" shortcut.
The docs show:

- /agent — Browse and select from available agents
- /skills — Manage skills for enhanced capabilities
- /plugin — Manage plugins and plugin marketplaces
- /mcp — Manage MCP server configuration

Could you check your changelog with /changelog to see the specific entry you're referring to? It's possible
the feature was renamed or the shortcut may differ from what was described. Which version's changelog
mentioned "extensions"?

● Changelog for v1.0.5

- Introducing /pr to help create and view PRs, automatically fix CI failures, address review feedback, and
resolve merge conflicts
- Add /extensions command to view, enable, and disable CLI extensions
- @ file mentions now support paths outside the project: absolute paths (@/usr/...), home directory
(@~/...), and relative parent paths (@../...)
- Send follow-up messages to background agents with the write_agent tool for multi-turn conversations
- Add /version command to display CLI version and check for updates from within the session
- Add experimental embedding-based dynamic retrieval of MCP and skill instructions per turn
- Syntax highlighting in /diff with support for 17 programming languages
- Add preCompact hook to run commands before context compaction starts
- Terminal title resets to default after running /clear or /new
- Right-click paste goes to the active dialog input instead of the main conversation input
- Block network (UNC) paths to prevent credential leakage via SMB authentication
- Show a clear error when a classic Personal Access Token (ghp_) is set in environment variables instead of
silently exiting
- Diff view displays correctly on Windows instead of showing corrupted/overwritten text
- Fix Kitty keyboard protocol escape sequences appearing at shutdown
- Setting claude-sonnet-4.6 as the default model is now preserved correctly
- Plugin uninstall reliably removes files using the stored install path

- PR descriptions with backtick-formatted code render correctly on Windows/PowerShell
- Show a helpful error message when a file path is passed as a CLI command
- Session reports an authentication error instead of hanging when the token is invalid or expired
- View tool shows partial content for large single-line files (e.g. minified JS, large JSON blobs) instead
of empty output
- Toggling experimental mode with /experimental on|off automatically restarts the CLI to apply changes
immediately
- Memory storage errors now indicate when repository doesn't exist or you lack write access
- /changelog supports `last `, `since `, and `summarize` to browse and summarize multiple
release notes at once
- Hooks config files that omit the version field are now accepted by the CLI

❯ verion 1.0.5, second item says " - Add /extensions command to view, enable, and disable CLI extensions"

● You're right, and that does appear to be a discrepancy. I'm currently running as version 1.0.5, and while
the changelog mentions /extensions, the actual help output shows /plugin instead — which covers similar
functionality (managing plugins and plugin marketplaces).

It's possible /extensions was renamed to /plugin before release, or it's a bug where the command wasn't
wired up. I'd suggest:

1. Try /plugin — it may be the equivalent command
2. Run /feedback to report the discrepancy to the GitHub Copilot CLI team directly
