/ in a Claude composer to see commands available to that runtime and working directory. The list includes provider commands and commands supplied by your configuration or plugins.
The available list changes with the bundled Claude version. Use that list rather than assuming every terminal command has an in-app equivalent.
Custom command locations
Create a Markdown file such as
.claude/commands/review-changes.md:
/review-changes from the command menu when it appears.
Arguments
Use$ARGUMENTS for the supplied text or positional arguments such as $1.
Commands and skills
Commands provide reusable prompts. Skills package broader instructions and supporting resources and can be selected when their task matches your request. A custom/create-pr or /code-review command exists only when your configuration supplies it. Use Git actions to create a PR directly.
Provider-native syntax follows the Claude skills and commands documentation.
