Claude Code | Tips (from its creator)

set-up

/allowed-tools: customize tool perms
/terminal-setup: enable shift + enter to insert new lines
/install-github-app: Tag @claude on issues and PRs
/theme: enable light/dark mode
/config: turn on notifications (turn on MacOS dictation)

tips

plan mode

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.

vimgrep

Vimcasts on vimgrep
Uses native vim regexes (which are slightly different from the regexes used by grep, ack, ag, etc) so the patterns are the same as with vim's within-file search patterns.

You can do a normal within-file search first, then re-use the same pattern to

	directive @requiredCapabilities(
	requiredCapabilities: [String!]
	) on ARGUMENT_DEFINITION \| ENUM \| ENUM_VALUE \| FIELD_DEFINITION \| INPUT_FIELD_DEFINITION \| INPUT_OBJECT \| INTERFACE \| OBJECT \| SCALAR \| UNION

	"""
	Marks an element of a GraphQL schema as only available via a preview header
	"""
	directive @preview(
	"""
	The identifier of the API preview that toggles this field.
