New Agent Prompt

When I use the agent-shell command with a prefix argument, I am given a minibuffer completion box. I expect typing "Cla" would immediately complete to Claude Code, but that's not what happens.

Instead, I have to to see all the options and then "Cla" works as expected.

I believe the leading icons are to blame for this annoyance

agent-shell/agent-shell.el

Line 1086 in 82a7fff

(cons (concat icon (when icon " ") display-name)

The easiest fix would be to delete them. I don't like the icons anyway as they provide no helpful information. I don't want corporate branding in my Emacs packages.

If you won't remove them, at least make them trailing instead please

Thanks for filing. Lemme see what I can provide...

In the meantime... I'm guessing you're not using a completion framework (ie. ivy, vertico, helm), correct?

If so, adding substring to your completion-styles may unblock ya.

For example:

(setq completion-styles '(substring basic partial-completion emacs22))

I realized the markdown swallowed something in my original report.

I meant: "I expect typing Cla<tab> would immediately complete to Claude Code, but that's not what happens. Instead, I have to type <tab> to see all the options and then Cla<tab> works as expected.

You are right I have no completion frameworks installed and adding substring to completion styles does remove the need for the extra tab press. It's a very minor issue but it's annoying to have to configure around it. I love the UX otherwise.
