Problem Statement

In 2.1.119, the slash command picker changed from truncating long descriptions to wrapping them onto a second line. I'd prefer to have truncation back, or at minimum a way to control it.

Skill descriptions serve double duty: they're shown in the autocomplete UI, but they're also read by the model to decide when to auto-invoke a skill. This means keeping descriptions short for display purposes directly reduces triggering accuracy — they need to be verbose to work well.

Truncation was fine because the autocomplete is just a visual hint; I know what my own skills do. Wrapping to two lines makes the picker feel cluttered when I have many skills.

Proposed Solution

Add a config option (e.g. slashCommandDescriptionWrap: false) to restore truncation behavior, or support a separate short display label in SKILL.md frontmatter (e.g. display_description) distinct from the full description used for model triggering.
