The correct option is /summarize which creates a brief overview of the open file. In Copilot Chat inside Visual Studio Code this chat command condenses the active file into a concise summary so you can review it quickly.

When you invoke the command, Copilot Chat uses the context of the file that is currently open and produces a high level description of its purpose, structure, and important elements. This is useful during code reviews and navigation because it lets you understand intent without reading every line.

/lint which runs your repository linter is incorrect because linting is handled by your configured linters or tasks in the editor and it is not a Copilot Chat slash command.

/autopilot which automatically completes entire functions is incorrect because there is no such chat command and Copilot provides inline suggestions for completions rather than a command that auto writes entire functions.

/clearcache which resets the Copilot chat backend is incorrect because there is no chat command to reset a backend cache and conversation management is handled by the chat UI controls instead.
