/open

Opens a path in the system default editor.

/open belongs to the Utilities category and forces a given path to open in the default editor configured on your system — outside the CLI, in your familiar environment with syntax highlighting, search, and all the editor features the plain terminal view doesn't offer. While typing, the command has supported shell-like path autocompletion since version 1.0.6, just like /add-dir — so you don't need to know the full filename by heart, but can complete it step by step. /open is the right choice when you want to keep editing a file manually or read through it at leisure, instead of only seeing it as a snippet in the terminal. If you just want to give the agent a file as context in the prompt without opening it separately, the @<path> reference in the prompt is the more direct route.
