Quick suffixes

A quick suffix is a saved snippet of instructions, such as Ask clarifying questions before you start., that you can add to a message in a click. It appears as a chip under the message box instead of being pasted into your text, so the message stays easy to edit.

Add a suffix to a message

Click Suffixes ▾ in the bar, or press Ctrl/Cmd+Shift+S.
Pick one from the menu. The first nine can be picked with the keys 1 to 9.

The suffix shows as a chip under the box. You can add several. A check mark in the menu is beside each suffix already on the message, and picking a checked one takes it off again. So does the × on its chip.

When you send, the suffixes are added in the order shown, after a blank line. The sent message in the conversation shows the full text, with the suffix part in a lighter style. A message can be only suffixes.

After a slash command

Claude Code takes everything after a command’s name as its arguments, so a message that starts with / puts its suffixes in a block of their own before the command. A command that runs a prompt, such as a skill or a custom command, gets them alongside that prompt, and its arguments stay what you typed. A local command such as /compact or /model doesn’t ask the model anything, so its suffixes change nothing.

Keep a suffix on

Right-click a chip and choose Keep on this tab (Stop keeping on this tab on a chip that’s kept). A kept suffix is added to every message in the tab until you turn it off, and its chip reads, for example, Plan only (kept). Kept suffixes are saved with the tab.

Give a suffix its own shortcut

A suffix can have a shortcut of its own that adds it directly. Set it in Settings → Keyboard → Quick suffixes, below.

Manage your suffixes

Settings → Keyboard → Quick suffixes lists them. Edit suffixes… at the foot of the Suffixes ▾ menu opens it.

Add suffix adds one. Give it a label, which shows in the menu and on the chip, and the text that’s added to the message.
The arrows ↑ and ↓ move a suffix, which also sets its number in the menu. Delete removes it.
Shortcut: click the button, then press the keys. Remove clears it. Claudette refuses a shortcut another command or suffix already uses.
The section’s Reset to defaults replaces the list with the five built-in suffixes. Your own are removed.
